[0004] According to the description of Patent Document 1, the diagnostic support device (tablet terminal) has an arithmetic unit, an information recording unit, an information transmission / reception unit, an input unit, and a display unit. In the information recording unit, life support record information, which is information on the content of life support provided by a caregiver or a nursing assistant to a subject, is recorded. The life support record information is, for example, information on the food intake, water intake, urine output, bowel movement output, urine state, stool state, and bathing state of the subject confirmed by a caregiver or a nursing assistant during life support.

[0005] Here, the amount of food and water consumed by the subjects is a type of assessment information regarding nutrition and dietary habits. Such assessment information is important because it is used in home medical care and home nursing to determine the risk of malnutrition and undernutrition. However, assessment information regarding nutrition and dietary habits belongs to the professional domain of registered dietitians and is highly specialized. Therefore, it is often difficult for caregivers, nursing assistants, or family members of patients providing care to input this assessment information. As a result, omissions (oversights) in inputting assessment information regarding nutrition and dietary habits are common.

[0006] This disclosure provides an information input support method, a data structure, and an information input support system that enable the prevention of omissions in the input of nutritional and dietary assessment information and the reduction of the effort required to input such information.

[0035] The evaluation information relates to the nutritional and dietary habits of the subject. In this embodiment, the evaluation information includes subject information (user information) and values ​​for multiple items (evaluation items). With respect to multiple items, the evaluation information does not necessarily need to include names that indicate multiple items. In other words, with respect to multiple items, the evaluation information may only include the values ​​for multiple items. However, if necessary, the evaluation information may include, for each of the multiple items, an association between the name that indicates the item and the value of the item.

[0036] The subject information concerns basic information for evaluating the subject's nutrition and dietary habits. This information includes the subject's identification number, name, date of birth, age, gender, evaluation date, and basic information. The basic information concerns the subject's physical condition. Examples of basic information include the level of care required, disease (primary disease, etc.), level of independence in daily living (bedridden), and level of independence in daily living (dementia).

For meal preparation and meal cleanup, the item values ​​may be given as options such as "3 or more times a week," "1-2 times a week," "rarely," "never," and "don't know." For shopping, the item values ​​may be given as options such as "1 or more times a week," "less than once a week," "rarely," "never," and "don't know." For appetite, the item values ​​may be given as options such as "very much," "yes," "average," "not very much," "almost never," and "don't know." For the amount of food needed to feel full, the item values ​​may be given as options such as "rarely feel full," "almost full after eating most of it," "full after about half," "full after about a third," "full after a few bites," and "don't know." Regarding the taste of the food, the item value can be given as a value indicating options such as "very delicious," "delicious," "average," "bad," "very bad," or "don't know." Regarding digestive symptoms, the item value can be given as a value indicating options such as "none," "nausea / vomiting," "abdominal bloating," "constipation," or "diarrhea." Regarding dentures, the item value can be given as a value indicating options such as "none," "complete dentures," "partial dentures," or "don't know."

Regarding assistance with eating, the item value can be given as a value indicating options such as "independent," "partially independent," "fully assisted," or "don't know." Regarding the time required for eating / meal, the item value can be given as a value indicating options such as "less than 30 minutes," "30 minutes or more," or "don't know." Regarding choking on liquids, the value for this item can be given as a choice of options such as "none," "yes," or "don't know."

[0040] Among multiple items, those classified as oral intake include, for example, the route of nutritional intake, the need for dysphagia-friendly food, the number of meals per day, the number of main meals, the number of side dishes, the number of snacks / meals between meals, and the intake of nutritional supplements (ONS). Regarding the route of nutritional intake, the item value may be given as a choice of options such as "oral intake," "tube feeding," and "intravenous intake." Regarding the need for dysphagia-friendly food, the item value may be given as a choice of options such as "none," "yes," and "don't know." Regarding the number of meals per day, the item value may be given as a choice of options such as "3 meals / day," "2 meals / day," "1 meal / day," "less than 1 meal / day," "4 or more meals / day," and "don't know." Regarding the number of main meals and the number of side dishes per meal, the item value may be given as a choice of options such as "can eat," "sometimes eat," "cannot eat," and "don't know." Regarding the intake of snacks / meals between meals and nutritional supplements (oral nutrition supplements (ONS)), the item value may be given as a choice of options such as "none," "yes," and "don't know."

[0041] Among the various items, those classified as required energy and water intake include, for example, basal metabolic rate, required energy, required water intake, assessment of nutrient intake, and assessment of water intake. Basal metabolic rate can be given, for example, by the Harris-Benedict equation. In the Harris-Benedict equation, the basal metabolic rate (kcal / day) for men is given by 66.473 + (13.7516 × weight (kg)) + (5.0033 × height (cm)) - (6.755 × age (years)). The basal metabolic rate (kcal / day) for women is given by 655.0955 + (9.5643 × weight (kg)) + (1.8496 × height (cm)) - (4.6756 × age (years)). The required energy is the amount of energy needed per day (kcal / day). The required energy can be calculated, for example, by the dietary intake standards determined by age and sex, a simplified formula given by current weight (kg) × 25-30 (kcal / day / kg), or total energy expenditure using the Harris-Benedict equation. The required water intake is the amount of water needed per day (L / day). The required water intake can be given, for example, by current weight (kg) × 30-35 (mL / day / kg). Regarding the evaluation of nutrient intake and water intake, the values ​​for each item can be given as options such as "sufficient," "insufficient," or "don't know."

[0042] Among multiple items, one item classified as medication status is, for example, medication status. Regarding medication status, the item's value can be given as a choice of options such as "none," "yes (5 types or less)," or "yes (6 types or more)."

[0043] In this embodiment, the multiple items included in the evaluation information include one or more independent items and one or more referenced items. An independent item is an item whose value cannot be determined from the values ​​of other items. A referenced item is an item whose value can be determined from the values ​​of other items. Regarding items classified as physical information, height, weight, most recent measured weight, perceived weight change, upper arm circumference, lower leg circumference, edema, and pressure ulcers are independent items. BMI can be calculated from height and weight. Specifically, BMI is calculated as weight [kg] ÷ (height [m]). 2It can be calculated as follows. The weight change rate can be calculated from the weight history. The weight change rate (compared to the previous measurement) [%] is calculated as (current weight - previous weight) / (previous weight) × 100. The value of the previous weight can be the most recent measurement. Regarding items classified as physical information, BMI and weight change rate are reference items.

[0044] [Content Database] The content database DB2 stores content. Multiple content items can be stored in the content database DB2. The content relates to nutrition and diet. Content stored in the content database DB2 is provided to the information terminal 2 as needed. Multiple content items include, for example, problem-solving content. Each problem-solving content item includes a problem related to nutrition and diet, and a solution to that problem. Examples of problems related to nutrition and diet include: "weight loss," "loss of appetite," "decreased eating and swallowing function," "difficulty with oral care," "nutritional support for people with dementia," "need for assistance with meal preparation and cooking," "takes a long time to eat," "unbalanced diet," "weight gain," "difficulty with fluid intake," "anxiety and concerns about enteral nutrition management," "anxiety and concerns about parenteral nutrition management," and "effects of medication on food and nutrition." The solutions provide a response plan for the corresponding problem. The response plan includes, for example, responses to the individual and caregiver, responses by professionals (doctors, pharmacists, registered dietitians, etc.), and items to monitor. The content of the solutions may be determined, for example, under the supervision of an expert regarding the corresponding problem. Multiple problem-solving content may share a common problem; that is, there may be multiple solutions to the same problem. Examples of problem-solving content include content addressing malnutrition and content addressing overnutrition. Multiple content may include content that displays external links to websites providing information on nutrition and diet.

[0045] [program] Program D1 includes an information input support program to assist in the input of evaluation information. In this embodiment, the information input support program works in cooperation with the web browser WB1 of the information terminal 2 to cause the arithmetic circuit 25 of the information terminal 2 to execute processing including evaluation information input processing and evaluation information output processing.

[0046] [Evaluation Information Input Processing] Figure 4 is a flowchart of an example of the evaluation information input process performed by the arithmetic circuit 25 of the information terminal 2.

[0047] The evaluation information input process is a process that executes an information input support method for inputting evaluation information about a subject's nutrition and dietary habits. The evaluation information input process includes a first step, a second step, a third step, and a fourth step. The first step is to display an input screen for inputting evaluation information about a subject's nutrition and dietary habits using the display device 221 of the information terminal 2. The evaluation information includes values ​​for multiple items. The input screen includes a first area that displays names indicating the multiple items and a second area that displays the values ​​of the multiple items. The multiple items include one or more independent items and one or more cited items. The second step is to accept input of at least one value of one or more independent items of the evaluation information using the input device 21 of the information terminal 2 while the input screen in the first step is being displayed. The third step is to calculate at least one value of one or more cited items based on the value of at least one independent item entered in the second step. The fourth step is to display at least one value of one or more cited items calculated in the third step in the second area of ​​the input screen.

[0048] The evaluation information input process will be explained in more detail below, with reference to Figure 4.

[0049] The calculation circuit 25 displays an input screen for inputting evaluation information regarding the subject's nutrition and diet on the display device 221 of the output device 22 (S11). Step S11 corresponds to the first step of the evaluation information input process.

[0050] Figures 5 to 12 are explanatory diagrams of an example of an input screen. The input screens in Figures 5 to 12 show input window W1 for inputting values ​​of items classified as physical information, among the values ​​of multiple items of evaluation information. Figures 5 and 6 show the same input screen, but in order to distinguish between the content displayed on the input screen and the reference codes etc. attached for the explanation of the input screen, reference codes etc. are not included in Figure 5, while they are included only in Figure 6. In other words, items that are listed only in Figure 6 and not in Figure 5 are not included in the content displayed on the input screen.

[0051] As shown in Figure 6, the input window W1 of the input screen includes the label L1, the first area R1, the second area R2, and the third area R3.

[0052] Label L1 displays the category of the item to be entered in input window W1. Input window W1 in Figure 6 is used to input values ​​for items classified as physical information. Label L1 in Figure 6 displays the text "Physical Information," which is the category of the item to be entered in input window W1.

[0053] The first area R1 displays names indicating multiple items of evaluation information. The names do not necessarily have to match the formal names of the items; they may be common names, abbreviations, coined words, etc., as long as the input person 20 can understand the meaning and content of the items. The first area R1 in Figure 6 includes name display areas N1 to N11 that display names indicating items of evaluation information, buttons B1 to B9 for displaying explanations about the items, and an explanation area T1.

[0054] Name display areas N1 to N11 display names indicating items classified as physical information. In Figure 6, name display areas N1 to N11 are arranged vertically.

[0055] In Figure 6, the name display area N1 corresponds to the "Height" item and displays the text "Height".

[0062] When button B4, which corresponds to the "Most Recent Measured Weight" item, is pressed, label L2 displays the text "Most Recent Measured Weight," and area 4 R4 displays the explanation for the "Most Recent Measured Weight" item. The explanation for the "Most Recent Measured Weight" item may include a message such as, "Let's compare your current weight with your previous weight to see how much your weight has changed. Rapid weight loss or gain may indicate poor control of your medical condition or nutritional deficiencies."

[0063] When button B5, which corresponds to the item "Awareness of weight change," is pressed, label L2 displays the text "Awareness of weight change (gained weight, lost weight, etc.)," ​​and domain 4 R4 presents an explanation for the item "Awareness of weight change." The explanation for the item "Awareness of weight change" may include a message such as, "Weight changes are an important indicator for checking nutritional deficiencies and the progression of illness. Let's share points that the person can notice in their daily life, such as whether their clothing size or belt length has changed, or whether their legs are swollen."

[0064] When button B6, which corresponds to the "Upper Arm Circumference" item, is pressed, label L2 displays the text "Upper Arm Circumference," and area 4 R4 displays the explanation for the "Upper Arm Circumference" item. The explanation for the "Upper Arm Circumference" item may include a message such as, "This is one alternative indicator when weight cannot be measured. Try measuring the circumference of the midpoint of the humerus on your non-dominant (non-paralyzed) hand. If it is less than 21 cm, there is a risk of malnutrition."

[0065] When button B7, which corresponds to the "calf circumference" item, is pressed, label L2 displays the text "calf circumference," and the fourth area R4 displays the explanation for the "calf circumference" item. The explanation for the "calf circumference" item may include a message such as, "This is one of the alternative indicators when weight cannot be measured. Try measuring the widest part of the calf that is free from paralysis or contracture. A measurement of less than 31 cm may indicate malnutrition."

[0066] When button B8, which corresponds to the "edema" item, is pressed, label L2 displays the word "edema," and area 4 R4 displays the explanation for the "edema" item. The explanation for the "edema" item may include messages such as, "Edema can occur not only due to the disease state and the effects of medication, but also due to a decrease in colloid osmotic pressure caused by malnutrition. Check your nutritional status. Rapid weight gain may also be influenced by edema."

[0067] When button B9, which corresponds to the "pressure ulcer" item, is pressed, label L2 displays the word "pressure ulcer," and domain 4 R4 presents the explanation for the "pressure ulcer" item. The explanation for the "pressure ulcer" item may include a message such as, "Reports indicate that malnutrition is the most strongly associated factor in the development of pressure ulcers in patients receiving home care (citation). Let's check for malnutrition risks along with daily care."

[0068] The explanation window W2 may be closed by moving outside the display area of ​​the explanation window W2, or by selecting a button displayed in the explanation window W2.

[0069] Explanation area T1 displays messages prompting the user to enter their height and weight. In Figure 6, explanation area T1 displays the message, "If you don't know your exact height and weight, try entering approximate values."

[0070] The second area R2 displays values ​​for multiple items. In Figure 6, the second area R2 includes value display areas F1~F6, F7a, F7b, F8, F9, F10a, F10b, F11a, F11b that display the values ​​for the evaluation information items, as well as a selection button PD1 and an explanation area T2.

[0071] The second area R2 is adjacent to the first area R1. More specifically, the second area R2 is adjacent to the first area R1 so that it is easy for a person to understand which of the name display areas N1 to N11 corresponds to each value display area F1 to F6, F7a, F7b, F8, F9, F10a, F10b, F11a, F11b. The value display areas F1 to F6, F7a, F7b, F8, F9, F10a, F10b, F11a, F11b display the values ​​of items classified as physical information. In Figure 6, the value display areas F1 to F6, F7a, F7b, F8, F9, F10a, F10b, F11a, F11b are located to the right of the corresponding name display areas N1 to N11 on the input screen (to the right from the perspective of the person viewing the input screen).

[0072] In Figure 6, value display area F1 corresponds to the "Height" item and displays the "Height" value as a numerical value. In Figure 6, value display area F2 corresponds to the "Weight" item and displays the "Weight" value as a numerical value. In Figure 6, value display area F3 corresponds to the "BMI" item and displays the "BMI" value as a numerical value. In Figure 6, value display area F4 corresponds to the "Most Recent Measured Weight" item and displays the "Most Recent Measured Weight" value as a numerical value. In Figure 6, value display area F5 corresponds to the "Weight Change Rate (Previous)" item and displays the "Weight Change Rate (Previous)" value as a numerical value. In Figure 6, value display area F6 corresponds to the "Weight Change Rate (1 Month)", "Weight Change Rate (3 Months)", and "Weight Change Rate (6 Months)" items and displays one of the values ​​for "Weight Change Rate (1 Month)", "Weight Change Rate (3 Months)", and "Weight Change Rate (6 Months)" as a numerical value. In Figure 6, value display area F8 corresponds to the "Upper Arm Circumference" item and displays the "Upper Arm Circumference" value as a numerical value. The value display area F9 in Figure 6 corresponds to the "Calf Circumference" item, and displays the value of "Calf Circumference" as a numerical value.

[0073] In Figure 6, the value display areas F7a and F7b correspond to the "Awareness of Weight Change" item and display the value of the "Awareness of Weight Change" item as text. Value display area F7a in Figure 6 corresponds to a value indicating "No awareness of weight change" (e.g., "0") and displays the text "None". Value display area F7b in Figure 6 corresponds to a value indicating "Awareness of weight change" (e.g., "1") and displays the text "Yes". Value display areas F7a and F7b in Figure 6 are in button format, and only one of the value display areas F7a or F7b can be selected.

[0074] In Figure 6, the value display areas F10a and F10b correspond to the "Edema" item and display the value of the "Edema" item as text. Value display area F10a in Figure 6 corresponds to a value indicating "No edema" (e.g., "0") and displays the text "None". Value display area F10b in Figure 6 corresponds to a value indicating "Edema is present" (e.g., "1") and displays the text "Present". Value display areas F10a and F10b in Figure 6 are in button format, and only one of the value display areas F10a or F10b can be selected.

[0075] In Figure 6, the value display areas F11a and F11b correspond to the "Pressure Ulcer" item and display the value of the "Pressure Ulcer" item as text. Value display area F11a in Figure 6 corresponds to a value indicating "No pressure ulcer" (e.g., "0") and displays the text "None". Value display area F11b in Figure 6 corresponds to a value indicating "Pressure ulcer present" (e.g., "1") and displays the text "Present". Value display areas F11a and F11b in Figure 6 are in button format, and only one of them can be selected.

[0076] The selection button PD1 is used to select the value of the item displayed in the value display area F6 from the values ​​of the items "Weight Change Rate (1 Month)", "Weight Change Rate (3 Months)", and "Weight Change Rate (6 Months)". The selection button PD1 is, for example, in the form of a pull-down menu (drop-down list) and can display "1 Month" for selecting "Weight Change Rate (1 Month)", "3 Months" for selecting "Weight Change Rate (3 Months)", and "6 Months" for selecting "Weight Change Rate (6 Months)".

[0077] The explanation area T2 is used to display the measurement date for the "most recent measured weight" item in the value display area F4, which corresponds to the "most recent measured weight" item.

[0078] The third area R3 indicates whether the input of values ​​for multiple items has been completed. The third area R3 in Figure 6 includes input status display areas C1 to C11, which show whether the input of values ​​for evaluation information items has been completed. Input status display areas C1 to C11 show whether the input of values ​​for items classified as physical information has been completed. Each input status display area C1 to C11 displays either an unentered image indicating that the input of the value for the corresponding item has not been completed, or an entered image indicating that the input of the value for the corresponding item has been completed. For example, each input status display area C1 to C11 is a checkbox, the unentered image is an image with a blank square, and the entered image is an image with a check mark inside a square. In Figure 6, since no values ​​have been entered for any of the items, each input status display area C1 to C11 displays the unentered image.

[0079] The third area R3 is adjacent to the first area R1. More specifically, the third area R3 is adjacent to the first area R1 so that it is easy for a person to understand which of the name display areas N1 to N11 corresponds to each input status display area C1 to C11. In Figure 6, the input status display areas C1 to C11 are located to the left of the corresponding name display areas N1 to N11 on the input screen (left side from the perspective of the person viewing the input screen). In Figure 6, the input status display areas C1 to C11 correspond to the "Height" item. In Figure 6, the input status display area C2 corresponds to the "Weight" item. In Figure 6, the input status display area C3 corresponds to the "BMI" item. In Figure 6, the input status display area C4 corresponds to the "Most Recent Measured Weight" item. In Figure 6, the input status display area C5 corresponds to the "Weight Change Rate (Previous Comparison)" item. In Figure 6, the input status display area C6 corresponds to the "Weight Change Rate (1 Month)", "Weight Change Rate (3 Months)", and "Weight Change Rate (6 Months)" items. In Figure 6, input status display area C7 corresponds to the item "Awareness of weight change". In Figure 6, input status display area C8 corresponds to the item "Upper arm circumference". In Figure 6, input status display area C9 corresponds to the item "Lower leg circumference". In Figure 6, input status display area C10 corresponds to the item "Edema". In Figure 6, input status display area C11 corresponds to the item "Pressure ulcer".

[0080] When displaying the input screen, the calculation circuit 25 may retrieve at least one value from the evaluation information database DB1 of multiple items included in the subject's past evaluation information and display it in the second area R2 of the input screen. In the second area R2 of the input screen in Figure 6, the value of the "height" item is likely to have not changed, so it is highly likely that the value of the "height" item from the subject's past evaluation information can be used. Therefore, the value of the "height" item included in the subject's past evaluation information can be displayed in the value display area F1 corresponding to the "height" item. In the second area R2 of the input screen in Figure 6, the value of the "most recent measured weight" item matches the value of the "weight" item from the subject's past evaluation information, so the value of the "weight" item from the subject's past evaluation information can be used. Therefore, the value of the "weight" item included in the subject's past evaluation information can be displayed in the value display area F4 corresponding to the "most recent measured weight" item. The most recent measured weight is the weight measured most recently among the previously measured weights. If there is no value for the "weight" item in the previous evaluation information, the value of the "weight" item in evaluation information from an even earlier period is referenced. For example, if the evaluation information from two evaluations ago contains a value for the "weight" item, that value may be used. However, if there is no value for the "weight" item in any of the past evaluation information, the value for the "most recent measured weight" item may be left blank. Thus, the first step may include retrieving at least one of the values ​​of multiple items included in the subject's past evaluation information from the evaluation information database DB1 and displaying it in the second area R2 of the input screen. This reduces the effort required for the input person 20 to input the evaluation information.

[0081] While the input screen described above is being displayed, the calculation circuit 25 receives input of at least one value for one or more independent items of evaluation information via the input device 21 (S12). The input screen in Figure 6 accepts input values ​​for height, weight, perceived weight change, upper arm circumference, lower leg circumference, edema, and pressure ulcers. Step S12 corresponds to the second step of the evaluation information input process.

[0082] When the arithmetic circuit 25 receives input of an independent item value of evaluation information via the input device 21 (S12: YES), it displays the input value of the independent item (S13). More specifically, the arithmetic circuit 25 displays the input value in the value display area corresponding to the independent item for which the value was input.

[0083] When the arithmetic circuit 25 receives input of a value for an independent item of evaluation information via the input device 21 (S12: YES), it changes the independent item for which a value has been entered to "input" (S14). More specifically, the arithmetic circuit 25 displays an "input" image in the input status display area corresponding to the independent item for which a value has been entered.

[0084] Figure 8 shows the state in the input screen where the value for the height item has been entered by the input device 21. The value display area F1 in Figure 8 shows the entered value for the height item (in Figure 8, "156"). In Figure 8, since only the value for the height item has been entered, only the input status display area C1 displays the entered image.

[0085] When the arithmetic circuit 25 receives input of the value of an independent item of the evaluation information via the input device 21 (S12:YES), it determines whether the value of the referenced item is operable (S15). If the value of the referenced item is operable (S15:YES), the arithmetic circuit 25 performs calculation on the value of the referenced item (S16). If the value of the referenced item is not operable (S15:NO), the arithmetic circuit 25 receives input of at least one value of one or more independent items of the evaluation information via the input device 21 (S12).

[0086] In Figure 8, the value for the height item is entered by the input device 21. Regarding the items classified as physical information, the reference items are BMI and weight change rate, and the values ​​of BMI and weight change rate cannot be calculated from the height value alone.

[0087] Figure 9 shows the input screen in Figure 8, with the weight value entered by the input device 21. The value display area F2 in Figure 9 shows the entered weight value (in Figure 9, "40.0"). In Figure 9, since the weight value has been entered, the input status display area C2 displays the input image.

[0088] Since the values ​​for height and weight have been entered by the input device 21, the BMI can be calculated. The calculation circuit 25 determines that the values ​​for the referenced items can be calculated (S15: YES) and calculates the values ​​for the referenced items and the BMI item (S16). Step S16 corresponds to the third step of the evaluation information input process.

[0089] The calculation circuit 25 calculates the value of the cited item (S16) and then displays the calculated value of the cited item (S17). More specifically, the calculation circuit 25 displays the input value in the value display area corresponding to the cited item for which the value has been calculated. In Figure 9, the value of the BMI item has been calculated, and the value display area F3 corresponding to the BMI item displays the calculated value of the BMI item (in Figure 9, "16.4"). Step S17 corresponds to the fourth step of the evaluation information input process.

[0090] When the calculation circuit 25 calculates the value of a reference item (S16), it changes the value of the reference item to "input" (S14). More specifically, the calculation circuit 25 displays the "input" image in the input status display area corresponding to the reference item for which the value has been calculated. In Figure 9, since the value of the BMI item has been calculated, the input status display area C3 displays the "input" image.

[0091] As shown in Figure 9, the input device 21 receives input values ​​for height and weight, which are then used to calculate the BMI value. As a result, value display area F1 shows the input value for height, value display area F2 shows the input value for weight, and value display area F3 shows the calculated BMI value. Input status display areas C1, C2, and C3 display the input images.

[0092] The second region R2 in Figure 9 includes the supplementary information display region P1. The supplementary information display region P1 displays supplementary information related to the corresponding item. The supplementary information displayed in the supplementary information display region P1 in Figure 9 shows the result of the obesity determination based on the value of the BMI item. The calculation circuit 25 generates supplementary information based on the value of the BMI item and displays the information indicating the supplementary information in the supplementary information display region P1. As an example, according to the Japan Society for the Study of Obesity's criteria, a BMI of less than 18.5 is classified as underweight (thin), a BMI of 18.5 or more and less than 25 is classified as normal weight, a BMI of 25 or more and less than 30 is classified as obese (grade 1), a BMI of 30 or more and less than 35 is classified as obese (grade 2), a BMI of 35 or more and less than 40 is classified as obese (grade 3), and a BMI of 40 or more is classified as obese (grade 4). In the case of Figure 9, the BMI is 16.4, which is underweight (thin). The supplementary information display region P1 in Figure 9 displays the message "Underweight (thin)".

[0093] Figure 10 shows the input screen in Figure 9 with the value for the most recent measured weight entered. The value for the most recent measured weight may be entered by the input device 21 or extracted from the evaluation information database DB1. In other words, if the subject's previous evaluation information is stored in the evaluation information database DB1, the value for the weight item can be referenced from the previous evaluation information. The value display area F4 in Figure 10 shows the entered value for the most recent measured weight item (in Figure 10, "42.0"). In Figure 10, since the value for the most recent measured weight item has been entered, the input status display area C4 displays the entered image. The explanation area T2 in Figure 10 displays the measurement date for the "most recent measured weight" (in Figure 10, January 2122) with respect to the value display area F4 corresponding to the "most recent measured weight" item.

[0094] In Figure 10, the weight change rate (compared to the previous measurement) can be calculated from the most recent measured weight and the current weight. The calculation circuit 25 determines that the values ​​of the referenced items and the weight change rate (compared to the previous measurement) can be calculated and calculates the weight change rate (compared to the previous measurement). As a result, the value display area F5 corresponding to the weight change rate (compared to the previous measurement) item displays the calculated value of the weight change rate (compared to the previous measurement) item (in Figure 10, "-4.8"). In Figure 10, since the value of the weight change rate (compared to the previous measurement) item has been entered, the input status display area C5 displays the input image.

[0095] If the measurement date for "Most recent measured weight" (January 2122 in Figure 10) corresponds to the weight one month ago, the weight change rate (1 month) can be calculated. In this case, the calculation circuit 25 calculates the value of the referenced item and the value of the weight change rate (1 month). As a result, the value display area F6 corresponding to the weight change rate (1 month) item displays the calculated value of the weight change rate (1 month) item ("-4.8" in Figure 10). In Figure 10, since the value of the weight change rate (1 month) item has been entered, the input status display area C6 displays the input image.

[0096] Figure 11 shows the input screen in Figure 10 with a value entered for the "perceived weight change" item. In Figure 11, the value for the "perceived weight change" item is entered by the input device 21, which selects the value display area F7a. Figure 11 shows that the value display area F7a is selected and the value display area F7b is not selected. In Figure 11, since a value for the "perceived weight change" item has been entered, the input status display area C7 displays the inputted image.

[0097] Figure 12 shows the input screen in Figure 11 with values ​​entered for upper arm circumference, lower leg circumference, edema, and pressure ulcer. Value display area F8 in Figure 12 shows the entered value for upper arm circumference (23.0 in Figure 12). Value display area F9 in Figure 12 shows the entered value for lower leg circumference (23.0 in Figure 12). In Figure 12, the value for edema is entered by selecting value display area F10b via input device 21. Figure 12 shows that value display area F10b is selected and value display area F10a is not selected. In Figure 12, the value for pressure ulcer is entered by selecting value display area F11a via input device 21. Figure 12 shows that value display area F11a is selected and value display area F11b is not selected.

[0098] The second region R2 in Figure 12 includes the supplementary information display region P2. The supplementary information display region P2 displays supplementary information related to the corresponding item. The supplementary information displayed in the supplementary information display region P2 in Figure 12 shows the result of the obesity determination based on the value of the calf circumference item. The calculation circuit 25 generates supplementary information based on the value of the calf circumference item and displays the information indicating the supplementary information in the supplementary information display region P2. For example, if the calf circumference is less than 31 cm, there is a risk of malnutrition. In Figure 12, the calf circumference is 23.0 cm, and there is a risk of malnutrition. The supplementary information display region P2 in Figure 11 displays the message "Risk present".

[0099] In Figure 12, since values ​​have been entered for all items, all input status display areas C1 to C11 display the completed image. After the input person 20 enters the values ​​for each item of the evaluation information using the information terminal 2, they can easily check in the third area R3 whether there are any missing entries.

[0100] In this embodiment, the evaluation information input process can be terminated at any time. For example, the input screen displays a termination button for ending the evaluation information input process. The arithmetic circuit 25 may terminate the evaluation information input process when the termination button is operated by the input device 21. In this embodiment, the evaluation information input process can be terminated even if there are items in the evaluation information for which no values ​​have been entered. This is because it may be difficult to determine the values ​​for some items, or it may not be possible to input values ​​due to the subject's condition or time constraints. In this embodiment, if at least one value does not exist for multiple items in the evaluation information, the arithmetic circuit 25 sets at least one of the multiple items to blank data. This allows the input of evaluation information to be terminated even if there are items for which no values ​​have been entered, thereby reducing the burden of inputting evaluation information.

[0101] [Evaluation information output processing] The evaluation information output process displays an output screen on the display device 221 that outputs the evaluation information input through the evaluation information input process. The arithmetic circuit 25 may execute the evaluation information output process in response to the input device 21 receiving confirmation of the end of the evaluation information input process, or it may execute the evaluation information output process immediately after the input of values ​​for the evaluation information items through the evaluation information input process is completed.

[0102] Figure 13 is an explanatory diagram of an example of an output screen. The output screen in Figure 13 shows a display window W11 for displaying the values ​​of items classified as physical information, among the values ​​of multiple items of evaluation information.

[0103] As shown in Figure 13, the display window W11 of the output screen includes labels L11, L12, and L13, as well as the first region R11, the second region R12, and the third region R13.

[0104] Labels L11 and L12 display the date of the evaluation information shown in the display window W11. Label L11 corresponds to the current evaluation information, i.e., the latest evaluation information. Label L12 corresponds to past evaluation information, or the previous evaluation information in Figure 13.

[0105] Label L13 displays the category of the item to be displayed in display window W11. Display window W11 in Figure 13 is used to display the values ​​of items classified as physical information. Label L13 in Figure 13 displays the text "Physical Information," which is the category of the item to be displayed in display window W11.

[0106] The first area R11 displays names indicating multiple items of evaluation information. In Figure 13, the first area R11 includes name display areas N21 to N33, which display names indicating items of evaluation information. Name display areas N21 to N33 display names indicating items classified as physical information. In Figure 13, name display areas N21 to N33 are arranged vertically. In Figure 13, the name display areas N21 to N33 correspond to the items "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively, and display the words "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change (e.g., lost weight, gained weight)," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively.

[0107] The second area R12 corresponds to the current evaluation information, that is, the latest evaluation information. The second area R12 displays the values ​​of multiple items in the current evaluation information. In Figure 13, the second area R12 includes value display areas F21 to F33 that display the values ​​of the evaluation information items. The second area R12 is adjacent to the first area R11. More specifically, the second area R12 is adjacent to the first area R11 so that it is easy for a person to understand which of the name display areas N21 to N33 each value display area F21 to F33 corresponds to. The value display areas F21 to F33 display the values ​​of items classified as physical information. In Figure 13, the value display areas F21 to F33 are located to the right of the corresponding name display areas N21 to N33 on the output screen (to the right from the perspective of the person viewing the input screen).

[0108] The value display areas F21 to F33 in Figure 13 correspond to the items "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively, and display the values ​​for "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change (e.g., lost weight, gained weight)," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively.

[0109] The third area R13 corresponds to the previous evaluation information, i.e., past evaluation information. The third area R13 displays the values ​​of multiple items from the previous evaluation information. In Figure 13, the third area R13 includes value display areas F41 to F53 that display the values ​​of the evaluation information items. The third area R13 is aligned horizontally with the second area R12. More specifically, the third area R13 is aligned horizontally with the second area R12 so that it is easy for a person to understand which of the name display areas N21 to N33 each value display area F41 to F53 corresponds to. The value display areas F41 to F53 display the values ​​of items classified as physical information. In Figure 13, the value display areas F41 to F53 are located to the right of the corresponding name display areas N21 to N33 on the output screen (to the right from the perspective of the person viewing the input screen).

[0110] The value display areas F41 to F53 in Figure 13 correspond to the items "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively, and display the values ​​for "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change (e.g., lost weight, gained weight)," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively.

[0111] As described above, the arithmetic circuit 25 can display an output screen on the display device 221 that outputs the evaluation information input through the evaluation information input process. Therefore, the input person 20 can input the evaluation information using the information terminal 2 and then confirm the input evaluation information on the output screen.

[0112] In this embodiment, the evaluation information output process can be terminated at any time. For example, the output screen displays a termination button for ending the evaluation information output process. The arithmetic circuit 25 may terminate the evaluation information output process when the termination button is operated by the input device 21. The output screen displays an edit button for re-executing the evaluation information input process in order to modify the evaluation information. The arithmetic circuit 25 may terminate the evaluation information output process and execute the evaluation information input process when the edit button is operated by the input device 21. This allows the input person 20 to check the evaluation information on the output screen and modify the entered evaluation information as needed. The output screen displays an output button for outputting the evaluation information. When the output button is operated by the input device 21, the arithmetic circuit 25 outputs the evaluation information data entered by the evaluation information input process in a predetermined file format (such as PDF format). The input person 20 can then output the entered evaluation information.

[0113] As shown in Figure 1, the information terminal 2 can communicate with the data management system 3 through the first communication network 81. This allows the arithmetic circuit 25 of the information terminal 2 to access the evaluation information database DB1 of the data management system 3. In this embodiment, the arithmetic circuit 25 stores the evaluation information input by the evaluation information input process in the evaluation information database DB1. More specifically, the arithmetic circuit 25 transmits the evaluation information input by the evaluation information input process to the data management system 3. The data management system 3 stores the evaluation information received from the arithmetic circuit 25 in the evaluation information database DB1. This allows the evaluation information database DB1 to store evaluation information for multiple subjects. The evaluation information database DB1 can store multiple evaluation records for the same subject with different dates and times (evaluation dates and times).

[0114] If the evaluation information database DB1 stores multiple evaluation records for the same subject with different dates (evaluation dates and times), the calculation circuit 25 can display a time-series record display screen on the display device 221, based on the multiple evaluation records for the same subject with different dates (evaluation dates and times). In other words, the calculation circuit 25 has the function of displaying at least one value of multiple items for the same subject in chronological order on the display device 221.

[0115] Figure 14 is an explanatory diagram of an example of a time-series record display screen. The time-series record display screen in Figure 14 shows a display window W21 for displaying the values ​​of items classified as physical information, among the values ​​of multiple items of evaluation information.

[0116] As shown in Figure 14, the display window W21 of the time-series record display screen includes labels L31, L41, L42, L43, and L51, as well as the first area R21, the second area R22, the third area R23, and the fourth area R24.

[0117] Label L31 displays a string indicating that the display window W21 is related to the time-series record display screen. In Figure 14, label L31 displays the words "Time-series record". Labels L41, L42, and L43 display the dates of the evaluation information displayed in the display window W21. Label L51 displays the category of the item displayed in the display window W21. In Figure 14, the display window W21 is used to display the values ​​of items classified as physical information. In Figure 14, label L51 displays the words "Physical Information", which is the category of the item displayed in the display window W21.

[0118] The first domain R21 displays names that indicate multiple items of evaluation information. In the first domain R11 of Figure 14, the names that indicate the items of evaluation information correspond to the items "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively, and the words "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change (e.g., lost weight, gained weight)," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively.

[0119] Each of the second to fourth domains R22 to R24 displays values ​​for multiple items in the evaluation information. The second to fourth domains R22 to R24 correspond to labels L41 to L43, respectively. In Figure 14, the dates of labels L41, L42, and L43 are in ascending order. Domain R22 corresponds to the most recent evaluation information, domain R23 corresponds to the next most recent evaluation information after domain R22, and domain R22 corresponds to the next most recent evaluation information after domain R23. Each of the second to fourth domains R22 to R24 corresponds to the items "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer," respectively, and displays the values ​​for "height," "weight," "BMI," "most recent measured weight," "weight change rate (compared to previous)," "weight change rate (1 month)," "weight change rate (3 months)," "weight change rate (6 months)," "perceived weight change (e.g., lost weight, gained weight)," "upper arm circumference," "calf circumference," "edema," and "pressure ulcer."

[0120] In the time-series recording screen of Figure 14, in the first domain R21, the names indicating the evaluation information items are arranged vertically. In each of the second to fourth domains R22 to R24, the values ​​of the evaluation information items are arranged horizontally alongside the names indicating the corresponding items, making it easier for people to understand the correspondence between the names indicating the evaluation information items.

[0121] As described above, the calculation circuit 25 displays at least one value from multiple items for the same subject in chronological order on the display device 221. Therefore, the history of evaluation information can be checked using the information terminal 2.

[0122] If the evaluation information database DB1 stores multiple evaluation records for the same subject with different dates (e.g., evaluation dates), the calculation circuit 25 can display a time-series change display screen that shows a graph of the evaluation information's changes over time, based on the multiple evaluation records for the same subject with different dates (e.g., evaluation dates). In other words, the calculation circuit 25 has the function of displaying a graph on the display device 221 that shows at least one value of multiple items for the same subject in chronological order.

[0123] Figure 15 is an explanatory diagram of an example of a time-series change display screen. The time-series change display screen in Figure 15 shows a display window W31 for displaying the values ​​of items classified as physical information, among the values ​​of multiple items of evaluation information.

[0124] As shown in Figure 15, the display window W31 of the time-series change display screen includes labels L61, L62, and L63, the first graph G11, and the second graph G12. Label L61 displays a string indicating the content of the graph shown in display window W31. Display window W31 in Figure 15 shows the time-series changes of weight and BMI. Label L61 in Figure 15 displays the text "Weight / BMI Graph". Labels L62 and L63 indicate the vertical axis of the graph. Label L62 corresponds to weight, and label L63 corresponds to BMI. The first graph G11 shows the time-series change of weight. The second graph G12 shows the time-series change of BMI. The first graph G11 in Figure 15 is based on the weight in the time-series recording screen of Figure 14. The second graph G12 in Figure 15 is based on the BMI in the time-series recording screen of Figure 14.

[0125] In Figure 15, the horizontal axis of the graph represents time, and the text "November 2121", "December 2121", "January 2122", and "February 2122" is displayed. In Figure 15, weight and BMI values ​​exist for "December 2121", "January 2122", and "February 2122", but not for "November 2121". This indicates that weight and BMI values ​​did not exist before "November 2121", meaning that evaluation information was not entered. The display window W31 of the time-series change display screen in Figure 15 shows the point in time when the item values ​​do not exist, making it intuitive to understand when evaluation information was entered.

[0126] As described above, the calculation circuit 25 displays graphs (first graph G11, second graph G12) on the display device 221 that show at least one value of multiple items for the same subject in chronological order. Therefore, the information terminal 2 can be used to easily check the changes in the evaluation information items over time.

[0127] As described above, if at least one value of multiple items in the evaluation information is missing after the evaluation information input processing is completed, the arithmetic circuit 25 sets at least one of the multiple items as blank data. When displaying a time-series change display screen as shown in Figure 15, if there is blank data, the graph may not be displayed correctly. Therefore, when displaying the graph, if at least one of the multiple items in the evaluation information for a specific date and time is blank data among multiple evaluation information for different dates and times, the arithmetic circuit 25 estimates the value of at least one of the multiple items in the evaluation information for the specific date and time based on the multiple evaluation information for different dates and times, and displays the estimated value of at least one of the multiple items in the evaluation information for the specific date and time on the graph.

[0128] For example, in the time-series recording screen of Figure 14, the weight value and BMI value of the evaluation information for the evaluation date 2122 / 01 / 01 are 42.0 and 17.3, but these are blank data. In this case, the calculation circuit 25 estimates the weight and BMI values ​​of the evaluation information for a specific date and time based on multiple evaluation information from different dates and times, and displays the weight and BMI values ​​of the evaluation information for that specific date and time obtained through estimation on a graph. More specifically, the calculation circuit 25 estimates the weight and BMI values ​​of the evaluation information for 2122 / 01 / 01 based on the evaluation information for the dates before and after the evaluation information for 2122 / 01 / 01, that is, the evaluation information for 2122 / 02 / 01 and the evaluation information for 2121 / 12 / 01.

[0129] The arithmetic circuit 25 may estimate the value of an item in the evaluation information for a specific date and time using conventionally known methods such as interpolation. For example, the arithmetic circuit 25 assumes that the weight value in the evaluation information for 2122 / 01 / 01 is the midpoint between the weight value in the evaluation information for 2122 / 02 / 01 and the weight value in the evaluation information for 2121 / 12 / 01. In Figure 14, the weight value in the evaluation information for 2122 / 02 / 01 is 40.0 kg, and the weight value in the evaluation information for 2121 / 12 / 01 is 43.0 kg, so the arithmetic circuit 25 estimates that the weight value in the evaluation information for 2122 / 01 / 01 is 41.5 kg.

[0130] For example, the arithmetic circuit 25 assumes that the BMI value of the evaluation information for 2122 / 01 / 01 is the midpoint between the BMI value of the evaluation information for 2122 / 02 / 01 and the BMI value of the evaluation information for 2121 / 12 / 01. In Figure 14, the BMI value of the evaluation information for 2122 / 02 / 01 is 16.4, and the BMI value of the evaluation information for 2121 / 12 / 01 is 17.7, so the arithmetic circuit 25 estimates that the BMI value of the evaluation information for 2122 / 01 / 01 is 17.1.

[0131] Figure 16 is an explanatory diagram of an example of a time-series display screen when the calculation circuit 25 estimates the values ​​of evaluation information items (weight and BMI). In Figure 16, the first graph G21 shows the time-series change in weight. The second graph G22 shows the time-series change in BMI. In the first graph G21 of Figure 16, the weight value of the evaluation information on 2122 / 01 / 01 is the estimated value (41.5 kg) derived from the weight value of the evaluation information on 2122 / 02 / 01 (40.0 kg) and the weight value of the evaluation information on 2121 / 12 / 01 (43.0 kg). In the second graph G22 of Figure 16, the BMI value of the evaluation information on 2122 / 01 / 01 is the estimated value (17.1) derived from the BMI value of the evaluation information on 2122 / 02 / 01 (16.4) and the BMI value of the evaluation information on 2121 / 12 / 01 (17.7).

[0132] In Figure 16, as in Figure 15, weight and BMI values ​​exist for "December 2121," "January 2122," and "February 2122," but not for "November 2121." This indicates that weight and BMI values ​​did not exist before "November 2121," meaning that evaluation information was not entered. The display window W31 of the time-series change display screen in Figure 16, as in Figure 15, shows the point in time when no values ​​exist for the items, making it intuitive to understand when evaluation information was entered.

[0133] As described above, if at least one of the multiple items of the evaluation information for a specific date and time is blank data among multiple evaluation information for different dates and times, the arithmetic circuit 25 estimates the value of at least one of the multiple items of the evaluation information for the specific date and time based on the multiple evaluation information for different dates and times, and displays the estimated value of at least one of the multiple items of the evaluation information for the specific date and time on the graph. This ensures that the graph is displayed correctly even when there is blank data in the evaluation information items.

[0134] [Content display program] The content display program is a program for displaying content stored in the content database DB2. In this embodiment, the content display program works in cooperation with the web browser WB1 of the information terminal 2 to cause the arithmetic circuit 25 of the information terminal 2 to execute content display processing for displaying the content.

[0135] The content display process is the process of executing a content display method for displaying content stored in the content database DB2. In the content display process, the arithmetic circuit 25 acquires content from multiple contents included in the content database DB2 in accordance with the input from the input device 21 and displays it on the display device 221. In this embodiment, as described above, the multiple contents include multiple problem-solving contents. Each of the multiple problem-solving contents includes a problem related to nutrition and diet, and a solution corresponding to that problem. In the content display process, the arithmetic circuit 25 displays the multiple problems included in the problem-solving contents and displays the solution corresponding to the problem selected from the problems of the multiple problem-solving contents among the solutions of the multiple problem-solving contents.

[0136] The content display process will be explained in more detail below. When the arithmetic circuit 25 displays the problems of multiple problem-solving content, it displays the problem display screen on the display device 221. Figure 17 is an explanatory diagram of an example of the problem display screen. The problem display screen in Figure 17 shows the problem display window W41 for selecting a problem.

[0137] As shown in Figure 17, the task display window W41 includes the display area M10 and the selection buttons B21 to B33.

[0138] Display area M10 displays a message prompting the user to select a task. In Figure 17, display area M10 displays the message, "Please select one of the common tasks."

[0139] Selection buttons B21 to B33 are used to select a problem. Each of the selection buttons B21 to B33 corresponds to a problem in multiple problem-solving content. Each of the selection buttons B21 to B33 displays a string of text indicating the corresponding problem. In Figure 17, selection buttons B21 to B33 correspond to "weight loss," "loss of appetite," "decreased eating and swallowing function," "difficulties with oral care," "nutritional support for people with dementia," "needs assistance with meal preparation and cooking," "takes a long time to eat," "unbalanced diet," "weight gain," "difficulties with fluid intake," "anxiety / concerns about enteral nutrition management," "anxiety / concerns about parenteral nutrition management," and "effects of medication on food and nutrition."

[0140] On the problem display screen, a problem can be selected by selecting one of the selection buttons B21 to B33 using the input device 21. The calculation circuit 25 displays the solution corresponding to the selected problem from among the solutions of multiple problem-solving content.

[0141] When the calculation circuit 25 displays a solution corresponding to the selected problem, it displays a solution display screen on the display device 221. Figure 18 is an explanatory diagram of an example of the solution display screen. More specifically, Figure 18 is an explanatory diagram of an example of the solution display screen when the selection button B21 in Figure 17 is selected. In other words, the solution display screen in Figure 18 is displayed when "I've lost weight" is selected as the specific problem. The solution display screen in Figure 18 shows the solution display window W42 for selecting a solution.

[0142] As shown in Figure 18, the solution display window W42 includes selection buttons B41-B59 and classification buttons B61-B66.

[0143] Selection buttons B41-B59 correspond to multiple problem-solving content, respectively. These buttons are used to select a specific problem-solving content from a set of solutions corresponding to multiple solutions for a particular problem. For example, for the problem "I've lost weight," there are multiple solutions, and selection buttons B41-B59 are used to select the most appropriate solution. These buttons also display strings indicating problems related to the corresponding solutions. These problems can serve as information to narrow down the solutions for the problem. The selection buttons B41-B59 in Figure 18 display the following text: "Increased energy expenditure due to illness, treatment, or metabolic changes," "Shortness of breath or difficulty breathing," "Decreased food intake due to insomnia or drowsiness," "Increased protein requirements due to changes in metabolism or absorption, inflammation, etc.," "Decreased food intake due to visual impairment," "Possible dysphagia due to sarcopenia," "Impaired eating or function due to cognitive impairment," "Ill-fitting dentures," "Irregular eating habits," "Fatigue and lethargy, leading to decreased food intake," "Lack of shopping and cooking experience," "Difficulty eating independently," "Decreased activity due to declining physical function," "Decreased activity due to reduced social interaction," "Weight loss due to eating alone," "Inability to change eating habits due to economic problems," "Living in an area where grocery shopping is inconvenient or difficult," "Insufficient food support due to caregiver burnout," and "Loss of appetite due to depression or stress."

[0144] Classification buttons B61-B66 are used to toggle the display of selection buttons B41-B59 based on the classification of the solution. Examples of solution classifications include "Disease / Medical Care," "Oral Care / Feeding / Swallowing," "Activities," "Environment," "Understanding / Preferences," and "Enteral / Venous Care." Solutions corresponding to selection buttons B41-B59 are classified into one of the following categories: "Disease / Medical Care," "Oral Care / Feeding / Swallowing," "Activities," "Environment," "Understanding / Preferences," and "Enteral / Venous Care." Classification buttons B61-B66 correspond to "Disease / Medical Care," "Oral Care / Feeding / Swallowing," "Activities," "Environment," "Understanding / Preferences," and "Enteral / Venous Care," respectively. By selecting any of the classification buttons B61-B66, the display of the selection buttons corresponding to the solutions included in the classification corresponding to the selected classification button is toggled. In Figure 18, the solutions for selection buttons B41-B45 are classified into "Disease / Medical Care." The solutions for selection buttons B46-B48 are classified into "Oral Care / Feeding / Swallowing." The solutions for selection buttons B49-B54 are classified as "Activities". The solutions for selection buttons B55-B58 are classified as "Environment". The solution for selection button B59 is classified as "Understanding / Preferences". Selection buttons B41-B59 do not include selection buttons corresponding to solutions classified as "Enteral / Venous". In Figure 18, classification button B61 toggles the display of selection buttons B41-B45. Classification button B62 toggles the display of selection buttons B46-B48. Classification button B63 toggles the display of selection buttons B49-B54. Classification button B64 toggles the display of selection buttons B55-B58. Classification button B65 toggles the display of selection button B59. Alternatively, the relationship between the classification buttons B61-B66 and the selection buttons B41-B59 may be visually represented by displaying icons indicating the classification of the solution on the classification buttons B61-B66 and the selection buttons B41-B59.

[0145] On the solution display screen, a solution can be selected by selecting one of the selection buttons B41 to B59 using the input device 21. When one of the selection buttons B41 to B59 is selected by the input device 21, the calculation circuit 25 displays the solution corresponding to the selected selection button on the display device 221.

[0146] Figure 19 shows the state in Figure 18 where the selection button B41 is selected by the input device 21. Figure 19 includes a solution display window W42. The solution display window W42 includes a solution display area R41. The solution display area R41 displays the content of the solution. In Figure 19, the solution display window W42 is located directly below the selection button B41, and the solution display area R41 displays the content of the solution corresponding to the selection button B41. Here, the solution display area R41 may display an external link to a website that provides information on nutrition and diet. In other words, at least one of the multiple contents included in the content database DB2 may display an external link to a website that provides information on nutrition and diet. This allows for the provision of additional information regarding nutrition and diet.

[0147] As described above, the calculation circuit 25 can display solutions to problems suitable for the target person on the display device 221, based on multiple problem-solving content included in the content database DB2.

[0148] In this embodiment, the content display process can be terminated at any time. For example, the solution display screen displays an exit button to terminate the content display process. The calculation circuit 25 may terminate the content display process when the exit button is operated by the input device 21. The solution display screen may display an output button to output the content of the selected solution. When the output button is operated by the input device 21, the calculation circuit 25 outputs the data of the selected solution in a predetermined file format (such as PDF). The input operator 20 can output the selected solution.

[0149] [Analysis System] The analysis system 4 shown in Figure 1 is used for analyzing evaluation information. The analysis system 4 is a so-called BI tool (Business Intelligence Tool). In this embodiment, the analysis system 4 can be implemented by, for example, one or more servers.

[0150] The analysis system 4 in Figure 1 is connected to the data management system 3 via a second communication network 82. The analysis system 4 can be implemented by, for example, one or more servers. The analysis system 4 can access the evaluation information database DB1. In other words, the analysis system 4 is permitted by the data management system 3 to access the evaluation information database DB1. In this embodiment, the analysis system 4 outputs statistical information based on the values ​​of multiple items in the subject's evaluation information and the subject's attribute information. The statistical information may include a cross-tabulation table created by cross-tabulation using the subject's attribute information and evaluation information. The subject's attribute information can be extracted from the subject information included in the evaluation information. In this embodiment, the subject's attribute information may include, for example, the subject's age, gender, and basic information. The statistical information makes it possible to understand the relationship between the subject's attribute information and the values ​​of multiple items in the subject's data. This facilitates analysis based on evaluation information.

[0151] [First Management Terminal] The first management terminal 5 in Figure 1 is used for managing the content database DB2. The first management terminal 5 is operated by the content manager 50. The content manager 50 manages the content of the content database DB2, for example. The first management terminal 5 can be implemented as, for example, a personal computer (desktop computer, laptop computer), a mobile device (smartphone, tablet device, etc.), etc. In this embodiment, the first management terminal 5 is implemented as a desktop computer.

[0152] The first management terminal 5 in Figure 1 is connected to the analysis system 4 and the data management system 3 via the second communication network 82. The first management terminal 5 can access the content database DB2. The first management terminal 5 can receive analysis results from the analysis system 4. The analysis results include, for example, statistical information based on the values ​​of multiple items in the subject's evaluation information and the subject's attribute information. Based on the statistical information from the analysis system 4, the content manager 50 can add content to the content database DB2, update existing content in the content database DB2, and delete content from the content database DB2.

[0153] [Second Management Terminal] The second management terminal 6 in Figure 1 is used for managing the data entry personnel 20. The second management terminal 6 is operated by a manager 60 from the management department of the organization to which the data entry personnel 20 belong. The manager 60, for example, manages the data entry personnel 20. The second management terminal 6 can be implemented as, for example, a personal computer (desktop computer, laptop computer), a mobile device (smartphone, tablet device, etc.), etc. In this embodiment, the second management terminal 6 is implemented as a desktop computer.

[0154] The second management terminal 6 in Figure 1 is connected to the data management system 3 via the first communication network 81. The data management system 3 may request an ID and password when the data entry person 20 accesses program D1 via the information terminal 2. The second management terminal 6 is used to manage the ID and password of the data entry person 20. For example, the second management terminal 6 can display a screen for editing the management information of the data entry person 20. The management information may include, for example, account information including the ID and password, and information about the data entry person 20 (name, job title, etc.). The administrator 60 can change the management information of the data entry person 20 as appropriate using the second management terminal 6.

[0155] [Third Management Terminal] The third management terminal 7 in Figure 1 is used to manage users of the services provided by the data management system 3 (for example, the use of program D1 and the associated evaluation information database DB1 and content database DB2) (for example, the organization to which the input personnel 20 and management personnel 60 in Figure 1 belong). The third management terminal 7 is operated by the administrator 70 of the organization operating the data management system 3. The administrator 70 manages users of the services provided by the data management system 3, for example. The third management terminal 7 can be implemented as, for example, a personal computer (desktop computer, laptop computer), a mobile terminal (smartphone, tablet terminal, etc.), etc. In this embodiment, the third management terminal 7 is implemented as a desktop computer.

[0156] The third management terminal 7 in Figure 1 is connected to the data management system 3 via the second communication network 82. The data management system 3 accepts applications for services provided by the data management system 3. The third management terminal 7 displays a screen for responding to applications for services provided by the data management system 3. The administrator 70 can respond to applications for services provided by the data management system 3 via the third management terminal 7.

[0157] [1.2 Effects, etc.] The system (information input support system) 1 described above comprises a display device 221 and an arithmetic circuit 25 connected to an input device 21. The arithmetic circuit 25 performs evaluation information input processing. The evaluation information input processing includes a first step, a second step, a third step, and a fourth step. The first step displays an input screen on the display device 221 for inputting evaluation information regarding the subject's nutrition and dietary habits. The evaluation information includes values ​​for multiple items, and the input screen includes a first area R1 that displays names indicating the multiple items and a second area R2 that displays values ​​for the multiple items. The multiple items include one or more independent items and one or more referenced items. The second step, while the input screen is displayed in the first step, accepts input of at least one value of one or more independent items of the evaluation information via the input device 21. The third step calculates at least one value of one or more referenced items based on at least one value of one or more independent items input in the second step. The fourth step displays at least one value from the one or more citation items calculated in the third step in the second area R2 of the input screen. This configuration prevents omissions in the input of nutritional and dietary assessment information and reduces the effort required to input such information.

[0158] In System 1, the input screen includes a third area R3 that indicates whether the input of values ​​for multiple items has been completed. The third area R3 is adjacent to the first area R1. This configuration makes it possible to prevent omissions in the input of evaluation information related to nutrition and dietary habits.

[0159] In System 1, the arithmetic circuit 25 executes an evaluation information output process that displays an output screen on the display device 221, which shows the evaluation information input through the evaluation information input process. This configuration allows users to check the input content of evaluation information related to nutrition and dietary habits.

[0160] In System 1, the arithmetic circuit 25 can access the evaluation information database DB1. The arithmetic circuit 25 stores the evaluation information input through the evaluation information input process in the evaluation information database DB1. This configuration facilitates the management of evaluation information related to nutrition and dietary habits.

[0161] In System 1, the information input support system 1 comprises an information terminal 2 equipped with an arithmetic circuit 25, and a data management system 3 that can communicate with the information terminal 2 and manages the evaluation information database DB1. The arithmetic circuit 25 transmits the evaluation information input by the evaluation information input process to the data management system 3. The data management system 3 stores the evaluation information received from the arithmetic circuit 25 in the evaluation information database DB1. This configuration facilitates the management of evaluation information related to nutrition and dietary habits.

[0162] In System 1, the evaluation information database DB1 stores multiple evaluation records for the same subject, each with different dates and times. The calculation circuit 25 displays at least one value from multiple items for the same subject on the display device 221 in chronological order. This configuration facilitates the evaluation of chronological changes in evaluation information related to nutrition and dietary habits.

[0163] In System 1, the arithmetic circuit 25 sets at least one of the evaluation information items to blank data if at least one of the items does not have a value. This configuration allows the input of evaluation information to be completed even if there are items with no values ​​entered, thereby reducing the burden of inputting evaluation information.

[0164] In System 1, the arithmetic circuit 25 displays graphs G21 and G22 on the display device 221, which show at least one value of multiple items for the same subject in chronological order. When displaying graphs G21 and G22, if at least one of the multiple items in the evaluation information for a specific date and time is blank data among multiple evaluation information for different dates and times, the arithmetic circuit 25 estimates the value of at least one of the multiple items in the evaluation information for the specific date and time based on the multiple evaluation information for different dates and times, and displays the estimated value of at least one of the multiple items in the evaluation information for the specific date and time on graphs G21 and G22. This configuration makes it easy to check the changes in the evaluation information items over time. This configuration also allows the graphs to be displayed correctly even when there is blank data in the evaluation information items.

[0165] In System 1, the first step includes retrieving at least one value from multiple items included in the subject's past evaluation information from the evaluation information database DB1 and displaying it in the second area R2 of the input screen. This configuration reduces the effort required to input evaluation information.

[0166] In System 1, the arithmetic circuit 25 can access a content database DB2 containing multiple content items related to nutrition and diet. These multiple content items include multiple problem-solving content items. Each of the multiple problem-solving content items includes a problem related to nutrition and diet, and a solution corresponding to that problem. When the arithmetic circuit 25 displays the multiple problem-solving content items on the display device 221, it displays the problems from the multiple problem-solving content items and displays the solution corresponding to the problem selected from the problems of the multiple problem-solving content items. This configuration allows for the display of solutions related to nutrition and diet that are tailored to the target audience.

[0167] In System 1, at least one of the multiple content items displays an external link to a website that provides information on nutrition and diet. This configuration can provide additional information on nutrition and diet.

[0168] In System 1, the arithmetic circuit 25 can access a content database DB2 containing multiple contents related to nutrition and diet. The arithmetic circuit 25 retrieves content from the multiple contents contained in the content database DB2 in accordance with the input from the input device 21 and displays it on the display device 221. This configuration can display content related to nutrition and diet.

[0169] System 1 includes an analysis system 4 that can access the evaluation information database DB1. The analysis system 4 outputs statistical information based on the values ​​of multiple items in the subject's evaluation information and the subject's attribute information. This configuration facilitates analysis based on evaluation information.

[0170] In System 1, one or more independent items include height and weight. One or more referenced items include BMI. Step 3 includes calculating the BMI value based on the height and weight values ​​entered in Step 2. This configuration reduces the effort required to input nutritional and dietary assessment information.

[0171] In System 1, each set of items includes at least two items related to physical information, dietary habits, oral intake, energy and fluid requirements, and medication status. This configuration enables accurate assessment based on nutritional and dietary information.

[0172] The information input support method described above is executed by the information terminal 2 and includes a first step, a second step, a third step, and a fourth step. The first step displays an input screen on the display device 221 for inputting evaluation information regarding the subject's nutrition and dietary habits. The evaluation information includes values ​​for multiple items, and the input screen includes a first area R1 that displays names indicating the multiple items, and a second area R2 that displays the values ​​of the multiple items. The multiple items include one or more independent items and one or more referenced items. The second step, while the input screen is displayed in the first step, accepts input of at least one value of one or more independent items of the evaluation information via the input device 21. The third step calculates at least one value of one or more referenced items based on the value of at least one independent item entered in the second step. The fourth step displays at least one value of one or more referenced items calculated in the third step in the second area R2 of the input screen. This configuration prevents omissions in the input of evaluation information regarding nutrition and dietary habits and reduces the effort required to input evaluation information regarding nutrition and dietary habits.

[0173] The program D1 described above is a program (computer program) that causes the information terminal 2 to execute the above-mentioned information input support method. This configuration makes it possible to prevent omissions in the input of evaluation information related to nutrition and dietary habits and to reduce the effort required to input such evaluation information.

[0174] [2. Example of Variables] The embodiments of this disclosure are not limited to those described above. The embodiments can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure can be achieved. The following lists some modifications of the embodiments. The modifications described below can be combined and applied as appropriate.

[0175] [2.1 Example of a Variable 1] Figure 20 is a block diagram of an example configuration of information terminal 2A in modified example 1. Information terminal 2 in Figure 20 includes an input device 21A, an output device 22, a communication device 23, a storage device 24, and an arithmetic circuit 25A.

[0176] The input device 21A includes a camera 212 in addition to the position input device 211 for the touch panel display. The camera 212 is used to acquire images of the subject. Examples of images of the subject may include images of the subject's body, images of the food the subject eats, and images of the subject's excrement.

[0177] The arithmetic circuit 25A, like the arithmetic circuit 25, performs evaluation information input processing based on the web browser WB1 and the program D1 of the data management system 3. In the evaluation information input processing of this modified example, the arithmetic circuit 25A acquires at least one value of a plurality of independent items based on the image obtained by the camera 212. In other words, in this modified example, the second step includes acquiring at least one value of a plurality of independent items based on the image obtained by the camera 212 of the input device 21A.

[0178] For example, values ​​for items classified as the subject's physical information in the evaluation information can be obtained from images of the subject's body. By performing image processing on images of the subject's body, values ​​for items classified as the subject's physical information can be obtained. As an example, it is possible to determine whether or not the subject has pressure ulcers from images of the subject's body. Conventional methods can be used to obtain the subject's physical information from images of the subject's body.

[0179] For example, values ​​for items classified as the subject's required energy and water intake can be obtained from images of the meals consumed by the subject. By performing image processing on images of the meals consumed by the subject, values ​​for evaluating nutrient intake and water intake can be obtained. Conventional methods can be used to obtain nutrient intake and water intake from images of meals.

[0180] For example, it becomes possible to determine a subject's bowel condition from an image of their excrement. If the evaluation information includes a section for bowel condition, it becomes possible to input a value for that section. Conventional methods can be used to obtain a subject's bowel condition from an image of their excrement.

[0181] In this modified version, the camera 212 can be used to input values ​​for independent items of evaluation information. Therefore, compared to directly inputting values ​​for independent items of evaluation information from the web browser WB1 using the position input device 211, the effort required to input evaluation information can be reduced.

[0182] As described above, the input device 21A includes a camera 212. The second step includes obtaining at least one value of a plurality of independent items based on the image obtained by the camera 212 of the input device 21. This configuration can reduce the effort required to input evaluation information.

[0183] [2.2 Variable Example 2] Figure 21 is a block diagram of an example configuration of information terminal 2B in modified example 2. Information terminal 2 in Figure 21 comprises an input device 21, an output device 22, a communication device 23, a storage device 24, and an arithmetic circuit 25B.

[0184] The arithmetic circuit 25B can communicate with the information acquisition device 91 via the communication device 23. The arithmetic circuit 25B may be able to communicate with two or more information acquisition devices 91 via the communication device 23.

[0185] The information acquisition device 91 acquires information about the subject. Examples of the information acquisition device 91 include an activity tracker that acquires the subject's activity level and a scale that acquires the subject's weight. Examples of information about the subject include the subject's activity level and the subject's weight.

[0186] The arithmetic circuit 25B, like the arithmetic circuit 25, performs evaluation information input processing based on the web browser WB1 and the program D1 of the data management system 3. In the evaluation information input processing of this modified example, the arithmetic circuit 25B acquires at least one value of a plurality of independent items based on the information obtained by the information acquisition device 91. In other words, in this modified example, the second step includes acquiring at least one value of a plurality of independent items based on the information obtained by the information acquisition device 91.

[0187] For example, the weight value in the evaluation information can be obtained from the subject's weight. For example, the value of the items classified as the subject's required energy and water intake in the evaluation information can be obtained from the subject's activity level. In particular, total energy expenditure can be determined from the activity level.

[0188] In this modified version, the information acquisition device 91 is used to input values ​​for independent items of evaluation information. Therefore, compared to directly inputting values ​​for independent items of evaluation information from the web browser WB1 using the position input device 211, the effort required to input evaluation information can be reduced.

[0189] As described above, the arithmetic circuit 25B can communicate with one or more information acquisition devices 91 that acquire information about the subject. The second step includes acquiring at least one value of a plurality of independent items based on the information about the subject obtained from one or more information acquisition devices 91. This configuration can reduce the effort required to input evaluation information.

[0190] [2.3 Variable Example 3] Figure 22 is a block diagram of an example configuration of information terminal 2C in modified example 3. The information terminal 2C in Figure 22 comprises an input device 21, an output device 22, a communication device 23, a storage device 24, and an arithmetic circuit 25C.

[0191] The arithmetic circuit 25C can communicate with the calling device 92 via the communication device 23. In particular, the arithmetic circuit 25C can communicate wirelessly with the calling device 92 via the communication device 23. The arithmetic circuit 25C may be able to communicate with two or more calling devices 92 via the communication device 23.

[0192] The arithmetic circuit 25C has the function of transmitting a call signal to the call device 92 in response to input from the input device 21. For example, the arithmetic circuit 25C displays a call button on the display device 221. When the call button is operated by the input device 21, the arithmetic circuit 25C transmits a call signal to the call device 92. The call button may be placed on the screen displayed on the display device 221 by the execution of program D1.

[0193] The calling device 92 is used to call a designated person. Examples of designated people include nurses, dietitians, and family members of the person being called. The calling device 92 executes a call in response to receiving a call signal from the arithmetic circuit 25C. The calling device 92 executes the call by sound or vibration, etc. The calling device 92 can be implemented, for example, by a mobile terminal (smartphone, tablet, etc.), a dedicated device, etc.

[0194] In this modified version, the call device 92 makes it possible to call the necessary person as needed. In particular, it makes it possible to call the necessary person as needed when inputting evaluation information related to nutrition and dietary habits. For example, if the condition of a subject changes while the subject is being visited and evaluation information is being input, a nurse can be called using the call device 92 and appropriate measures can be taken. In this case, the information terminal 2 functions as a nurse call system. For example, if there are questions about inputting evaluation information while the subject is being visited and evaluation information is being input, a registered dietitian can be called using the call device 92 for consultation.

[0195] As described above, the arithmetic circuit 25C can communicate with the calling device 92. The arithmetic circuit 25C transmits a call signal to the calling device 92 in response to the input from the input device 21. The calling device 92 executes the call in response to receiving the call signal from the arithmetic circuit 25C. This configuration makes it possible to call the necessary person as needed.

[0196] [2.4 Variable Example 4] Figure 23 is a block diagram of an example configuration of System 1D in Modification 4. System 1D in Figure 23 comprises information terminals 2-1, 2-2, ..., 2-n, a data management system 3D, and browsing terminals 93-1, 93-2, ..., 93-n (hereinafter collectively referred to as reference numeral 93). System 1D in Figure 23, like System 1 in Figure 1, comprises an analysis system 4, a first management terminal 5, a second management terminal 6, and a third management terminal 7.

[0197] The viewing terminal 93 in Figure 23 is used to view evaluation information regarding the subject's nutrition and dietary habits. As shown in Figure 23, viewing terminals 93-1, 93-2, ..., 93-n are operated by viewing users 930-1, 930-2, ..., 930-n (hereinafter collectively referred to as 930). Viewing users 930 are, for example, the subject themselves, related parties (related parties to the subject), and medical professionals. Related parties to the subject are people who share the subject's evaluation information. Examples of related parties to the subject include family members, caregivers, and people who consult on matters concerning the subject.

[0198] Figure 24 is a block diagram of an example configuration of a browsing terminal 93. The browsing terminal 93 in Figure 24 comprises an input device 931, an output device 932, a communication device 933, a storage device 934, and an arithmetic circuit 935. The browsing terminal 93 can be implemented by, for example, a personal computer (desktop computer, laptop computer), a mobile terminal (smartphone, tablet terminal, etc.), etc. In this embodiment, the browsing terminal 93 is implemented by a tablet terminal.

[0199] The input device 931 is used to input information from a user 930 or other person to the browsing terminal 93. The input device 931 is equipped with one or more human-machine interfaces for information input. One or more human-machine interfaces of the input device 931 include a position input device 931a for a touch panel display.

[0200] The output device 932 is used to output information from the viewing terminal 93 to a user 930 or other person. The output device 932 is equipped with one or more human-machine interfaces for information output. In this modified example, one or more human-machine interfaces of the output device 932 include a display device 932a which is a touch panel display.

[0201] The communication device 933 is used for communication with the data management system 3D via the first communication network 81.

[0202] The storage device 934 is used to store information used by the arithmetic circuit 935 and information generated by the arithmetic circuit 935. The storage device 934 includes one or more storage devices (non-temporary storage media). The information stored in the storage device 934 includes the web browser WB2.

[0203] The arithmetic circuit 935 is a circuit that controls the operation of the browsing terminal 93. The arithmetic circuit 935 is connected to the input device 931, the output device 932, and the communication device 933, and has access to the storage device 934. The arithmetic circuit 935 can be implemented, for example, by a computer system including one or more processors (microprocessors) and one or more memories.

[0204] The viewing terminal 93 is connected to the data management system 3D via the first communication network 81. The viewing terminal 93 can access the evaluation information database DB1. In other words, the viewing terminal 93 is authorized by the data management system 3 to access the evaluation information database DB1.

[0205] In the data management system 3D, program D1 includes a viewing program that enables viewing of evaluation information regarding the nutrition and dietary habits of subjects via the viewing terminal 93. The viewing program works in cooperation with the web browser WB2 of the viewing terminal 93 to cause the calculation circuit 935 of the viewing terminal 93 to execute a judgment process and either a first viewing process or a second viewing process.

[0206] The determination process determines the eligibility to view the evaluation information. The determination process determines whether the person or a related party is eligible to view the evaluation information, or whether a medical professional is eligible. For example, in the determination process, the arithmetic circuit 935 receives the identification information of the viewing user 930 and determines the eligibility to view based on the input identification information of the viewing user 930.

[0207] The arithmetic circuit 935 executes the first viewing process if the person entitled to view the evaluation information is the person themselves or a related party. The arithmetic circuit 935 executes the second viewing process if the person entitled to view the evaluation information is a medical professional.

[0208] The first browsing process displays a portion of several items of evaluation information obtained from the evaluation information database DB1. Examples of some of the items of evaluation information that can be viewed in the first browsing process include items that are desirable to be shared among the individual and related parties, such as items classified as dietary habits and oral intake. This allows caregivers and family members to comment on the individual's preferences and dietary history, enables parents of the individual to share information about the individual's situation, facilitates the exchange of information on dietary support, and creates connections among those who care for the individual.

[0209] The second viewing process displays all of the multiple items of the evaluation information obtained from the evaluation information database DB1. If the viewing privilege is that of a healthcare professional, all of the multiple items of the evaluation information can be viewed, which enables appropriate measures and guidance to be taken for the subject.

[0210] Thus, in this modified example, the evaluation information shared differs depending on the viewing qualifications of the viewing user 930. If the viewing qualification is that of a healthcare professional, all of the multiple items of the evaluation information are viewable, while if the viewing qualification is that of the individual or a related party, only some of the multiple items of the evaluation information are viewable.

[0211] As described above, System 1D includes a viewing terminal 93 that can communicate with the evaluation information database DB1. If the viewing terminal 93 is authorized to view the evaluation information, it performs a first viewing process that displays a portion of several items of the evaluation information obtained from the evaluation information database DB1. If the viewing terminal 93 is authorized to view the evaluation information, it performs a second viewing process that displays all of several items of the evaluation information obtained from the evaluation information database DB1. This configuration makes it possible to restrict access to evaluation information related to nutrition and dietary habits.

[0212] [2.5 Variable Example 5] In the system 1 of the above embodiment, the calculation circuit 25 can access the content database DB2 which contains multiple contents related to nutrition and diet. In this modified system, after the evaluation information input processing is completed, the calculation circuit 25 prioritizes displaying a specific content from among the multiple contents on the display device 221. This makes it possible to prioritize the display of specific contents related to nutrition and diet after the evaluation information input processing is completed.

[0213] Specific content may be associated with the target audience. This configuration allows for the display of nutrition and dietary content tailored to the target audience. Specific content may be predetermined for each target audience via the input device 21.

[0214] The following example shows how specific content can be set for multiple problem-solving content. In this example, the arithmetic circuit 25 displays a screen for registering "favorites" for multiple problem-solving content using the display device 221. The input person 20 may select problem-solving content to register as "favorites" from among the multiple problem-solving content using the input device 21. As an example, the input person 20 can register problem-solving content related to the target person as "favorites" from among the multiple problem-solving content. The input person 20 can register problem-solving content that corresponds to the target person's issues as identified from the target person's evaluation information, that is, problem-solving content that is predicted to be frequently referenced in relation to the target person as "favorites". Problem-solving content registered as "favorites" is treated as specific content. In other words, specific content is selected by the person inputting the evaluation information (input person 20) from among multiple content based on whether it is frequently referenced in relation to the target person. By registering as "favorites", the effort of searching for frequently referenced content in relation to the target person from among multiple content can be reduced. Therefore, the effort of displaying nutrition and dietary content appropriate for the target person can be reduced.

[0215] Figure 25 is an explanatory diagram of an example of the solution display screen in Modification Example 5. Similar to Figure 18, Figure 25 is an explanatory diagram of an example of the solution display screen when the selection button B21 is selected in Figure 17. In other words, the solution display screen in Figure 25 is displayed when "I've lost weight" is selected as the specific problem. The solution display screen in Figure 25 shows the solution display window W42 for selecting a solution.

[0216] The solution display window W42 in Figure 25, like the solution display window W42 in Figure 18, includes selection buttons B41-B59 and classification buttons B61-B66. Each of the selection buttons B41-B59 corresponds to one of several problem-solving content items. In Figure 25, the selection buttons B41-B59 are arranged in this order from top to bottom. In Figure 25, the selection buttons B41, B42, and B43 display an icon L1 indicating that they are "favorites" (i.e., specific content items). In Figure 25, three problem-solving content items corresponding to "disease, treatment, metabolic changes, and increased energy expenditure" and "shortness of breath, difficulty breathing" are registered as "favorites". As a result, the top three selection buttons B41-B43 are associated with the three problem-solving content items corresponding to "disease, treatment, metabolic changes, and increased energy expenditure" and "shortness of breath, difficulty breathing". In this way, the three problem-solving contents corresponding to "illness, treatment, metabolic changes, and increased energy expenditure" and "shortness of breath, difficulty breathing" are displayed with priority over other problem-solving contents. Figure 18 shows the solution display screen when "favorites" are not registered. Comparing this to Figure 18, it can be seen that in Figure 25, the three problem-solving contents corresponding to "illness, treatment, metabolic changes, and increased energy expenditure" and "shortness of breath, difficulty breathing" are displayed with priority.

[0217] As described above, the arithmetic circuit 25 can access the content database DB2, which contains multiple contents related to nutrition and diet. After the evaluation information input process is completed, the arithmetic circuit 25 retrieves a specific content from the content database DB2 and displays it on the display device 221. This configuration allows for the priority display of specific content related to nutrition and diet after the evaluation information input process is completed.

[0218] Specific content is associated with the target individual corresponding to the evaluation information entered during the evaluation information input process. The specific content is selected by the person entering the evaluation information from among multiple pieces of content, based on how frequently it is referenced in relation to the target individual. This configuration reduces the effort required to display nutrition and dietary content tailored to the target individual.

[0219] [2.6 Variable Example 6] In this modified system, the evaluation information includes the nutritional status of the subject. The nutritional status of the subject may be determined based on the value of at least one of several items included in the evaluation information.

[0220] Examples of nutritional status include undernutrition and overnutrition.

[0221] Malnutrition can be classified into several risk categories depending on its severity. For example, malnutrition can be categorized as low-risk, intermediate-risk, or high-risk.

[0222] The risk classification for malnutrition uses values ​​for BMI, weight change rate, nutritional support method, and pressure ulcers. A BMI of 18.5 or higher but less than 30 indicates a low risk of malnutrition. A BMI of less than 18.5 indicates a moderate or high risk of malnutrition. A weight change rate, especially weight loss rate, of less than 3% indicates a low risk of malnutrition. A weight loss rate of 3% or more but less than 5% per month indicates a moderate risk of malnutrition. A weight loss rate of 5% or more per month indicates a high risk of malnutrition. A weight loss rate of 3% or more but less than 7.5% over three months indicates a moderate risk of malnutrition. A weight loss rate of 7.5% or more over three months indicates a high risk of malnutrition. A weight loss rate of 3% or more but less than 10% over six months indicates a moderate risk of malnutrition. A weight loss rate of 10% or more over six months indicates a high risk of malnutrition. If the nutritional support method is enteral nutrition or parenteral nutrition, the risk of malnutrition is moderate or high. If pressure ulcers are present, the risk of malnutrition is high.

[0223] When two or more of the following items are combined: BMI, weight change rate, nutritional support method, and pressure ulcers, if all items are low risk, the malnutrition risk will be considered low; if any item is high risk, the malnutrition risk will be considered high; and in all other cases, the malnutrition risk will be considered moderate.

[0224] Overnutrition can be classified into several risk categories depending on its severity. For example, overnutrition can be categorized as low-risk, medium-risk, or high-risk. Body Mass Index (BMI) is used to classify the risk of overnutrition. A BMI of less than 25 indicates a low risk of overnutrition. A BMI between 25 and 30 indicates a medium risk of overnutrition. A BMI of 30 or higher indicates a high risk of overnutrition.

[0225] In this modified example, the evaluation information input process further includes determining the nutritional status based on at least one of the values ​​of multiple items included in the evaluation information. That is, in the evaluation information input process, the arithmetic circuit 25 determines the nutritional status based on at least one of the values ​​of multiple items included in the evaluation information. The arithmetic circuit 25 determines a specific content based on the nutritional status determined based on at least one of the values ​​of multiple items included in the evaluation information.

[0226] The following examples illustrate how specific content can be set for multiple problem-solving content. In this example, the calculation circuit 25 determines specific content from multiple problem-solving content based on nutritional status. If the nutritional status is malnutrition, the calculation circuit 25 selects problem-solving content corresponding to the solution of the malnutrition problem as specific content from the multiple problem-solving content. Furthermore, the calculation circuit 25 may determine specific content from multiple problem-solving content based on the risk classification of malnutrition. If the nutritional status is overnutrition, the calculation circuit 25 selects problem-solving content corresponding to the solution of the overnutrition problem as specific content from the multiple problem-solving content. Furthermore, the calculation circuit 25 may determine specific content from multiple problem-solving content based on the risk classification of overnutrition.

[0227] Figure 26 is an explanatory diagram of an example of the solution display screen in modified example 6. Similar to Figure 18, Figure 26 is an explanatory diagram of an example of the solution display screen when the selection button B21 is selected in Figure 17. In other words, the solution display screen in Figure 26 is displayed when "I've lost weight" is selected as the specific problem. The solution display screen in Figure 26 shows the solution display window W42 for selecting a solution.

[0228] The solution display window W42 in Figure 26, like the solution display window W42 in Figure 18, includes selection buttons B41-B59 and classification buttons B61-B66. Selection buttons B41-B59 correspond to multiple problem-solving content, respectively. In Figure 26, selection buttons B41-B59 are arranged from top to bottom in this order. In Figure 26, selection buttons B41, B42, and B43 display icon L2, indicating that they are specific content determined based on nutritional status. In Figure 26, the specific content consists of two problem-solving content items corresponding to "reduced food intake due to insomnia / somnolence" and "reduced food intake due to fatigue / lethargy," respectively. As a result, the two problem-solving content items corresponding to "reduced food intake due to insomnia / somnolence" and "reduced food intake due to fatigue / lethargy," respectively, are associated with the first two selection buttons from the top, B41 and B42, among the selection buttons B41-B59. In this way, the two problem-solving content items corresponding to "reduced food intake due to insomnia / somnia" and "reduced food intake due to fatigue and lethargy" are displayed with priority over other problem-solving content items. Figure 18 is a solution display screen where no specific content is set. Comparing it with Figure 18, it can be seen that in Figure 26, the two problem-solving content items corresponding to "reduced food intake due to insomnia / somnia" and "reduced food intake due to fatigue and lethargy" are displayed with priority.

[0229] As described above, the evaluation information includes the nutritional status of the subject. The evaluation information input process further includes determining the nutritional status based on at least one of the values ​​of multiple items included in the evaluation information. The calculation circuit 25 determines specific content based on the nutritional status. This makes it possible to determine and display content related to nutrition and dietary habits that is appropriate for the subject.

[0230] In this modified example, the arithmetic circuit 25 determines a specific content from among multiple problem-solving content based on the nutritional status determined based on at least one of the values ​​of multiple items included in the evaluation information. The information of the specific content determined in this way may be included in the evaluation information. In other words, the specific content may be associated with the evaluation information.

[0231] Figure 27 is an explanatory diagram of an example of the time-series record display screen in this modified example. The time-series record display screen in Figure 27 shows a display window W22 for displaying the values ​​of items classified as physical information among the values ​​of multiple items of evaluation information.

[0232] As shown in Figure 27, the display window W22 of the time-series record display screen includes labels L31, L41, L42, L43, L51, the first area R21, the second area R22, the third area R23, the fourth area R24, and the content information display area R31.

[0233] The content information display area R31 in Figure 27 includes the label L52 and the confirmation buttons B71, B72, and B73.

[0234] Label L52 displays a string indicating that the content information display area R31 relates to specific content associated with the evaluation information. In other words, label L52 displays a string indicating that the content information display area R31 relates to specific content determined based on the nutritional status of the subject included in the evaluation information. In Figure 27, label L52 displays the text "Registered Food and Nutrition Issues".

[0235] Confirmation buttons B71-B73 are used to confirm the content of specific information determined based on the nutritional status of the subject included in the evaluation information. Confirmation buttons B71-B73 correspond to evaluation information corresponding to the second-to-fourth domains R22-R24, respectively. Confirmation buttons B71-B73 display the word "Confirm". For example, when confirmation button B71 is operated by input device 21, a window presenting the content of specific information associated with the evaluation information corresponding to domain 2 R22 is displayed in front of display window W22. This makes it possible to confirm the content of specific information associated with the evaluation information.

[0236] In the time-series recording screen shown in Figure 27, confirmation buttons B71 to B73 are arranged vertically alongside the evaluation information represented by the second to fourth domains R22 to R24, respectively, to make it easier for users to understand their correspondence.

[0237] As described above, the arithmetic circuit 25 can output the evaluation information data input by the evaluation information input process in a predetermined file format (such as PDF format). If the evaluation information includes information on specific content, the output evaluation information may also include information on that specific content. This allows the information on the specific content to be displayed together with the evaluation information when it is displayed on the display device 221 during the evaluation information output process. Information on specific content included in the evaluation information may be carried over when inputting evaluation information for the same subject next time. In other words, the next evaluation information may already include information on specific content included in the previous evaluation information.

[0238] [2.7 Variable Example 7] In the system of Modified Example 6, the nutritional status of the subject is determined in the evaluation information input process performed by the calculation circuit 25 based on at least one of the values ​​of multiple items included in the evaluation information. In other words, the determination of the subject's nutritional status is performed by calculations in the calculation circuit 25. However, the nutritional status does not necessarily have to be determined by calculations in the calculation circuit 25. In the system of this modified example, instead of the evaluation information input process determining the nutritional status based on at least one of the values ​​of multiple items included in the evaluation information by the calculation circuit 25, the nutritional status may be input by the input device 21. In other words, the input person 20 may determine the nutritional status based on at least one of the multiple items of the evaluation information and input it using the input device 21. In this case, the calculation circuit 25 determines specific content based on the nutritional status input by the input device 21.

[0239] As described above, in this modified example, the evaluation information includes the nutritional status of the subject. The evaluation information input process further includes receiving input of the nutritional status via the input device 21. The calculation circuit 25 determines specific content based on the nutritional status. This makes it possible to determine and display content related to nutrition and dietary habits appropriate for the subject.

[0240] [2.8 Variable Example 8] Figure 28 is an explanatory diagram of an example of a solution display screen shown by the system of Modification Example 8. The solution display screen in Figure 28 shows a solution display window W43 for selecting a solution.

[0241] As shown in Figure 28, the solution display window W43 includes selection buttons B41-B51, category buttons B61-B66, tabs TB1 and TB2, label L53, filter button B81, and add buttons B91-B101. Note that the solution display window W43 in Figure 28 has fewer selection buttons than the solution display window W42 in Figure 18; this is simply to make the diagram easier to read. The solution display window W43 in Figure 28 may also include selection buttons B41-B59, similar to the solution display window W42 in Figure 18.

[0242] Tabs TB1 and TB2 indicate groups of multiple content (problem-solving content in Figure 28). In other words, multiple problem-solving content may be grouped together. As mentioned above, evaluation information may include the nutritional status of the subject, and examples of the subject's nutritional status include malnutrition and overnutrition. Multiple problem-solving content may be related to either malnutrition or overnutrition, or both. Therefore, by displaying problem-solving content related to malnutrition separately from problem-solving content related to overnutrition, it becomes easier to select the appropriate problem-solving content. In Figure 28, tabs TB1 and TB2 are used to switch between malnutrition and overnutrition. Tab TB1 displays the string "malnutrition" in relation to malnutrition. Tab TB2 displays the string "overnutrition" in relation to overnutrition. When tab TB1 is selected, the solution display window W43 displays a selection button for selecting problem-solving content related to malnutrition, and when tab TB2 is selected, the solution display window displays a selection button for selecting problem-solving content related to overnutrition. Tabs TB1 and TB2 may be displayed on the problem display screen in Figure 17. In Figure 17, when the malnutrition tab is selected, selection buttons for selecting problems in the malnutrition problem-solving content may be displayed, and when the overnutrition tab is selected, selection buttons for selecting problems in the overnutrition problem-solving content may be displayed.

[0243] The filtering button B81 is used to sort the selection buttons B41-B51. The filtering button B81 is in the form of a pull-down menu (drop-down list) and displays a string corresponding to the sorting key for selection buttons B41-B51. The sorting key corresponds to the nutritional status issues of the subject. Examples of issues include: "losing weight," "lack of appetite," "decreased eating and swallowing function," "difficulty with oral care," "nutritional support for people with dementia," "need for assistance with meal preparation and cooking," "takes a long time to eat," "unbalanced diet," "weight gain," "difficulty with fluid intake," "anxiety / concerns about enteral nutrition management," "anxiety / concerns about parenteral nutrition management," and "effects of medication on food and nutrition." When an issue is selected using the filtering button B81, for example, selection buttons B41-B51 are sorted from top to bottom in order of relevance to the issue selected using the filtering button B81. Label L53 displays text to encourage selection using the filtering button B81. In Figure 28, label L53 displays the text "Points of Interest to Observe". In Figure 28, label L53 is positioned horizontally next to the filtering button B81 so that it is easy for people to understand its correspondence with the filtering button B81.

[0244] The add buttons B91 to B101 are used to associate the corresponding content (problem-solving content in Figure 28) with evaluation information. In Figure 28, the add buttons B91 to B101 are arranged horizontally next to each of the selection buttons B41 to B51 so that it is easy for a person to understand the correspondence with the problem-solving content corresponding to each selection button B41 to B51. The add buttons B91 to B101 display icons indicating that the problem-solving content is to be associated with evaluation information. For example, when the add button B91 is operated by the input device 21, a window is displayed in front of the solution display window W43 to confirm whether to associate the problem-solving content corresponding to selection button B41 with evaluation information. By performing an operation on the input device 21 to confirm that the problem-solving content corresponding to selection button B41 is to be associated with evaluation information (for example, by selecting the OK button displayed in the window), the problem-solving content corresponding to selection button B41 is associated with evaluation information. This makes it easier to associate content (especially problem-solving content) with evaluation information.

[0245] The solution display screen shown in Figure 28, as described above, includes tabs TB1 and TB2, which indicate groups of multiple problem-solving content. This makes it possible to display problem-solving content in groups, thus making it easier to select the appropriate problem-solving content.

[0246] The solution display screen shown in Figure 28, as described above, includes a filtering button B81. The filtering button B81 is used to rearrange the selection buttons B41-B51. The selection buttons B41-B51 are rearranged in order of their relevance to the issue selected by the filtering button B81. This makes it easier to select the appropriate problem-solving content.

[0247] The solution display screen shown in Figure 28, as described above, includes additional buttons B91-B101 for associating content with evaluation information. This makes it easier to associate content with evaluation information.

[0248] [2.9 Examples of other variables] In one modified example, the arithmetic circuit 25 may display a notification on the display device 221 prompting the input of the next evaluation information after a predetermined time has elapsed since the previous input of evaluation information. The predetermined time is not particularly limited, but for example, it may be the time corresponding to one month. Examples of notifications prompting the input of the next evaluation information include messages such as "How is Mr. / Ms. XX doing?" or "The evaluation has not been performed for a long time." The notification prompting the input of the next evaluation information may be displayed on the display device 221 in various forms. This configuration makes it possible to prevent the omission of input of the evaluation information itself.

[0249] In one modified example, the first step of the evaluation information input process may include determining multiple items according to the subject's attribute information. In other words, multiple items of the evaluation information may be changed according to the subject. This means switching multiple items of the evaluation information according to the subject. This makes it possible to determine and display the items to be entered according to the subject's attribute information on the input screen, thereby supporting the input person 20 in determining the values ​​of the items and enabling the input of appropriate item values. The subject's attribute information may include at least one of the subject's age and disease. For example, the items to be evaluated may differ for elderly people and children. In the first step, if the subject is determined to be elderly based on the subject's attribute information, multiple items of the evaluation information are set to items for the elderly. In the first step, if the subject is determined to be a child based on the subject's attribute information, multiple items of the evaluation information are set to items for children. For example, the items to be evaluated may differ depending on whether or not there is a mental illness. In the first step, if the subject is determined to have a mental illness based on the subject's attribute information, multiple items of the evaluation information are set to items for people with mental illness. The first step involves determining, based on the subject's attribute information, that the subject does not have a mental illness, and then setting several items of the evaluation information to items for healthy individuals. The subject's attribute information is not limited to the subject's age and illness. For example, the subject's attribute information may include the subject's age, gender, and basic information. Examples of basic information include the level of care required, illness (primary illness, etc.), level of independence in daily living (degree of being bedridden), and level of independence in daily living (state of dementia). Thus, the first step may include determining multiple items according to the subject's attribute information. The attribute information may include at least one of the subject's age and illness. This makes it possible to determine the items to be entered according to the subject's attribute information and display them on the input screen. Therefore, it becomes possible to facilitate the input of evaluation information.

[0250] In one modified example, the input screen displays an explanation of how to determine the value of at least one of one or more independent items. As an example, in the above embodiment, as shown in Figure 7, an explanation window W2 presenting an explanation of the items is displayed in front of the input window W1. The explanation window W2 in Figure 7 includes a label L2 and a fourth area R4. In the explanation window W2 for independent items, the fourth area R4 may include an explanation of how to determine the value of the independent item. This enables the input person 20 to support the determination of the value of the independent item and to input an appropriate value. The explanation of how to determine the value of the independent item may be changed according to the subject's attribute information. The subject's attribute information may include at least one of the subject's age and disease. This is because some items in the evaluation information have different methods of determining the value depending on the subject's age or disease. As an example, basal metabolic rate, required energy amount, etc., may change depending on the subject's age or disease. The subject's attribute information can be extracted from the subject information included in the evaluation information. The subject's attribute information is not limited to the subject's age and disease. The subject's attribute information may include, for example, the subject's age, gender, and basic information. Examples of basic information include the level of care required, diseases (primary diseases, etc.), level of independence in daily living (bedridden), and level of independence in daily living (dementia status). Thus, the input screen will display an explanation of how to determine the value of at least one of the one or more independent items. The content of the explanation may be changed according to the subject's attribute information. The attribute information may include at least one of the subject's age and disease. This enables the input of appropriate values ​​according to the subject. This facilitates the input of evaluation information.

[0251] In one modified example, the analysis system 4 may have a function to assist in the creation of medical claim forms (receipts). A medical claim form is a detailed statement of medical fees that a medical institution claims from the insurer (health insurance association, etc.) for insured medical treatment received by a patient. A medical claim form includes personal information such as the patient's name, gender, and date of birth, the patient's health insurance enrollment information, the name of the medical institution making the claim, the medical department, the name of the disease, and points for medications, injections, procedures, surgeries, tests, diagnostic imaging, rehabilitation, etc., performed during the month of treatment. The analysis system 4 may output information used to create medical claim forms based on evaluation information obtained from the evaluation information database DB1. This makes it easier to create medical claim forms. The analysis system 4 may also create and output the medical claim form itself from the information used to create the medical claim form. Thus, system 1 may include an analysis system 4 that can access the evaluation information database DB1. The analysis system 4 may output information used to create medical claim forms based on evaluation information obtained from the evaluation information database DB1. This makes it easier to create medical claim forms.

[0252] In one modified example, the arithmetic circuit 25 may determine the display order of at least one of the issues and solutions of multiple problem-solving content based on the correlation between the evaluation information stored in the evaluation information database DB1 and the selection results of multiple problem-solving content for the evaluation information. The arithmetic circuit 25 can determine the degree of relevance of multiple issues to the evaluation information input in the evaluation information input process based on the correlation. As shown in Figure 17, when displaying a list of multiple issues, the arithmetic circuit 25 can set the display order of the multiple issues based on the degree of relevance of the multiple issues to the evaluation information. For example, the display order of multiple issues can be set in order of increasing relevance to the evaluation information. The arithmetic circuit 25 can determine the degree of relevance of multiple solutions to the evaluation information input in the evaluation information input process based on the correlation. As shown in Figure 18, when displaying a list of multiple solutions, the arithmetic circuit 25 can set the display order of the multiple solutions based on the degree of relevance of the multiple solutions to the evaluation information. For example, the display order of multiple solutions can be set in order of increasing relevance to the evaluation information. The correlation between evaluation information and the selection results of multiple issues and multiple solutions for the problem-solving content related to the evaluation information may be obtained by analysis by the analysis system 4. Thus, the calculation circuit 25 may be able to access the content database DB2 which contains multiple contents related to nutrition and diet. The multiple contents include multiple problem-solving contents. Each of the multiple problem-solving contents includes an issue related to nutrition and diet, and a solution corresponding to that issue. The calculation circuit 25 may determine the display order of at least one of the issues and solutions of the multiple problem-solving contents according to the correlation between the evaluation information stored in the evaluation information database DB1 and the selection results of the multiple problem-solving contents related to the evaluation information. This makes it possible to display nutrition and diet content that is appropriate for the target person.

[0253] In one modified example, the arithmetic circuit 25 may perform either a first evaluation information input process or a second evaluation information input process as the evaluation information input process. More specifically, the arithmetic circuit 25 performs the first evaluation information input process if the person qualified to input the evaluation information is the person themselves or a related party, and performs the second evaluation information input process if the person qualified to input the evaluation information is a medical professional. The first evaluation information input process has fewer inputtable items in the evaluation information than the second evaluation information input process. Since some items of the evaluation information require a certain level of knowledge to input, input of such items is made impossible for the person themselves or a related party, and only medical professionals are allowed to input them. This makes it possible to input appropriate values. As mentioned above, the multiple items included in the evaluation information can be classified, for example, into physical information, diet, oral intake, required energy and fluid intake, and medication status. In the first evaluation information input process, only items classified as physical information and diet may be inputtable, while in the second evaluation information input process, all items may be inputtable. Thus, in System 1, the arithmetic circuit 25 executes a first evaluation information input process as the evaluation information input process if the person qualified to input the evaluation information is the person themselves or a related party, and executes a second evaluation information input process as the evaluation information input process if the person qualified to input the evaluation information is a medical professional. The first evaluation information input process has fewer input items than the second evaluation information input process. This makes it possible to set input restrictions on evaluation information related to nutrition and dietary habits.

[0254] The icon L1 indicating "favorites," as explained in Modification 6, and the icon L2 indicating specific content determined based on nutritional status, as explained in Modification 7, may be used simultaneously. In other words, content may have both icons L1 and L2 attached at the same time.

[0255] In one modified example, multiple items may include additional items that can only be entered if the value of a specific item is a specific value. For example, the specific item is "dentures," and the additional item is "denture status." The value of the "dentures" item can be, for example, "none," "complete dentures," "partial dentures," or "unknown." The value of the "denture status" item can be, for example, "fit," "poor fit," or "unknown." The value of the "dentures" item can be entered using buttons corresponding to "none," "complete dentures," "partial dentures," or "unknown." If the button corresponding to "none" or "unknown" is selected for the value of the "dentures" item, input of the value of the "denture status" item is not required. If the button corresponding to "complete dentures" or "partial dentures" is selected for the value of the "dentures" item, input of the value of the "denture status" item is required. In this case, the value of the "denture status" item can be entered using buttons corresponding to, for example, "fit," "poor fit," or "unknown." In other words, in the input of items, the options branch out, and selecting a specific option makes new options available.

[0256] In one modified example, the format for inputting item values ​​is not limited to a format that allows direct value input, such as value display area F1, or a button format, such as value display areas F7a and F7b. The format for inputting item values ​​may be a pull-down menu (drop-down list). For example, for the item "pressure ulcers," a pull-down menu may allow selection of "yes" or "no." Using a pull-down menu makes it possible to present many options. For example, as mentioned above, in an item classified as required energy and fluid intake, required energy can be determined by the total energy consumption using the Harris-Benedict equation. In this case, the value of the stress coefficient (SF) may be selectable via a pull-down menu. As an example, the pull-down menu may include options such as "0.6 (e.g., starvation, etc.)", "0.8 (e.g., bone marrow injury, starvation, etc.)", "1.1 (e.g., cancer, etc.)", ..., "1.6 (e.g., pressure ulcers, fever (39°C), etc.".

[0257] In one modified example, the input device 21 may have a microphone. In the evaluation information input processing, the arithmetic circuit 25 may obtain the values ​​of one or more items (in particular, independent items) of the evaluation information based on the sound input to the microphone of the input device 21.

[0258] In one modified example, program D1 may operate independently rather than in cooperation with the web browser WB1. In this case, program D1 may be stored in the storage device 24 of the information terminal 2.

[0259] In one modified example, the data management system 3 may be implemented using a computer system consisting of multiple servers or other devices. In other words, it is not essential that the multiple functions (components) of the data management system 3 are consolidated within a single enclosure; the components of the data management system 3 may be distributed across multiple enclosures. Furthermore, at least some of the functions of the data management system 3, for example, some of the functions of the arithmetic circuit 35, may be implemented by the cloud (cloud computing), etc.

[0260] In one modified example, the information terminal 2 may have the functions of the data management system 3. For example, the storage device 24 of the information terminal 2 may store the program D1, the evaluation information database DB1, and the content database DB2.

[0261] In one modified example, at least one of the analysis system 4, the first management terminal 5, the second management terminal 6, and the third management terminal 7 is optional and not mandatory. In system 1 of Figure 1, the arithmetic circuit 25 of the information terminal 2 performs the evaluation information input processing, but the arithmetic circuit 35 of the data management system 3 may perform the evaluation information input processing, or the arithmetic circuits 25 and 35 may cooperate to perform the evaluation information input processing.

[0262] In one modified example, the information terminal 2 does not need to have the function to store evaluation information in the evaluation information database DB1 of the data management system 3. If the function to accumulate the evaluation information of the subject is not implemented, the information terminal 2 does not need to be able to access the evaluation information database DB2 of the data management system 3. The information terminal 2 may simply display the evaluation information entered through the evaluation information input process using the display device 221, and the entered evaluation information may be discarded when the web browser WB1 is closed.

[0263] In one modified example, the content display process is an optional element. If the content display process function is not implemented, the information terminal 2 does not need to be able to access the content database DB2 of the data management system 3.

[0264] [3. Appearance] As is clear from the above embodiments and modifications, this disclosure includes the following aspects. In the following, reference numerals are enclosed in parentheses solely to indicate their correspondence with the embodiments. Note that, for the sake of readability, the notation of reference numerals enclosed in parentheses may be omitted after the first occurrence.

[0265] The first aspect is an information input support system (1), which includes an arithmetic circuit (25) connected to a display device (221) and an input device (21). The arithmetic circuit (25) executes evaluation information input processing. The evaluation information input processing includes a first step, a second step, a third step, and a fourth step. The first step is to display an input screen for inputting evaluation information regarding the nutrition and diet of a subject on the display device (221). The evaluation information includes values of a plurality of items, and the input screen includes a first area (R1) for displaying names indicating the plurality of items and a second area (R2) for displaying values of the plurality of items. The plurality of items includes one or more independent items and one or more reference items. The second step is to accept input of values of at least one of the one or more independent items of the evaluation information by the input device (21) during the display of the input screen in the first step. The third step is to calculate values of at least one of the one or more reference items based on values of at least one of the one or more independent items input in the second step. The fourth step is to display values of at least one of the one or more reference items calculated in the third step in the second area (R2) of the input screen. This aspect enables prevention of omission in input of evaluation information regarding nutrition and diet and reduction of the labor involved in input of evaluation information regarding nutrition and diet.

[0266] The second aspect is an information input support system (1) based on the first aspect. In this aspect, the input screen includes a third area (R3) indicating whether input of values of the plurality of items has been completed. The third area (R3) is adjacent to the first area (R1). This aspect enables prevention of omission in input of evaluation information regarding nutrition and diet.

[0267] The third aspect is an information input support system (1) based on the first or second aspect. In this aspect, the arithmetic circuit (25) executes evaluation information output processing to display an output screen for outputting the evaluation information input by the evaluation information input processing on the display device (221). This aspect enables confirmation of the input content of evaluation information regarding nutrition and diet.

[0268] The fourth embodiment is an information input support system (1) based on any one of the first to third embodiments. In this embodiment, the arithmetic circuit (25) can access the evaluation information database (DB1). The arithmetic circuit (25) stores the evaluation information input by the evaluation information input process in the evaluation information database (DB1). This embodiment facilitates the management of evaluation information related to nutrition and dietary habits.

[0269] The fifth embodiment is an information input support system (1) based on the fourth embodiment. In this embodiment, the information input support system (1) comprises an information terminal (2) equipped with the arithmetic circuit (25), and a data management system (3) that can communicate with the information terminal (2) and manages the evaluation information database (DB1). The arithmetic circuit (25) transmits the evaluation information input by the evaluation information input process to the data management system (3). The data management system (3) stores the evaluation information received from the arithmetic circuit (25) in the evaluation information database (DB1). This embodiment facilitates the management of evaluation information related to nutrition and dietary habits.

[0270] The sixth embodiment is an information input support system (1) based on the fourth or fifth embodiment. In this embodiment, the evaluation information database (DB1) stores multiple evaluation information items for the same subject at different dates and times. The calculation circuit (25) displays at least one value of the multiple items for the same subject in chronological order on the display device (221). This embodiment facilitates the evaluation of chronological changes in evaluation information related to nutrition and dietary habits.

[0271] The seventh embodiment is an information input support system (1) based on the sixth embodiment. In this embodiment, the arithmetic circuit (25) sets at least one of the multiple items as blank data if at least one of the multiple items in the evaluation information does not have a value. This embodiment allows the input of evaluation information to be completed even if there are items for which no value has been entered, and reduces the burden of inputting evaluation information.

[0272] The eighth aspect is an information input support system (1) based on the seventh aspect. In this aspect, the calculation circuit (25) displays on the display device (221) a graph (G21, G22) that displays at least one value of the plurality of items for the same subject in chronological order. When displaying the graph (G21, G22), if at least one of the plurality of items of the evaluation information for a specific date and time among the plurality of evaluation information for different dates and times is blank data, the calculation circuit (25) estimates the value of at least one of the plurality of items of the evaluation information for the specific date and time based on the plurality of evaluation information for different dates and times, and displays the estimated value of at least one of the plurality of items of the evaluation information for the specific date and time on the graph (G21, G22). This aspect makes it easy to check the changes in the evaluation information items over time.
