Description

Technical Field

[0001] The present application relates to the field of medical care technology, and in particular to a method, device, storage medium and equipment for evaluating nutritional intake of hemodialysis patients. Background Art

[0002] In the dialysis treatment scenario of uremia and other hemodialysis patients, dry weight refers to the lowest weight that the hemodialysis patient can tolerate after hemodialysis, which is generally estimated by the doctor based on the patient's condition. Before hemodialysis treatment, the doctor will weigh the patient to obtain the patient's pre-dialysis weight. The pre-dialysis weight minus the dry weight will give the patient's weight change between dialysis sessions, which can be used to preliminarily assess the amount of water retained in the patient's body, and then combined with the patient's blood pressure and edema to determine the patient's dialysis ultrafiltration volume for the day. In practice, generally speaking, the allowable range of weight gain between dialysis sessions is within 5% of dry weight. Controlling interdialysis weight gain is of great significance. Failure to control diet will lead to excessive weight gain between dialysis sessions, which will overburden the kidneys, causing edema of organs throughout the body, heart failure and other problems.

[0003] In the related art, the dietary nutrition for hemodialysis patients is required to meet the needs of the body and avoid malnutrition, while also preventing excessive production of metabolic waste. In current practice, nutritional assessment and dietary recommendations generally estimate daily energy requirements based on the subject's height, weight, and age, and then, based on this, use the food exchange method to prepare daily menus based on the ratio of the three major nutrients.

[0004] In the process of realizing the present invention, the inventors found that this method did not fully take into account the characteristics of hemodialysis treatment, which often led to poor dietary control of dialysis patients in practice, prone to malnutrition, high incidence of complications and other problems.

[0005] Therefore, how to achieve more targeted nutritional intake assessment for hemodialysis patients to facilitate better interdialysis dietary control has become a technical problem that needs to be solved urgently.

[0006] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0007] In order to overcome the problems existing in the related art at least to a certain extent, the embodiments of the present application provide a method, device, storage medium and equipment for evaluating the nutritional intake of hemodialysis patients.

[0021] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] Figure 1 It is a schematic diagram of an application scenario of a method for assessing nutritional intake of hemodialysis patients according to some embodiments of the present application.

[0023] like Figure 1As shown, the terminal device 101 or 102 sends the obtained individual basic information of the dialysis patient and the laboratory test result information to the server 104 through the network 103 . The server 104 receives the individual basic information and laboratory examination result information, calculates and generates intermediate data that characterizes the patient's daily nutrition component demand information based on the individual basic information, and calculates and determines the deviation information of each inspection index value and the indicator control value based on the laboratory examination result information, adjusts the intermediate data based on the deviation information of the first type of indicator in the deviation information to obtain the processed target data; and then recommends food output based on the daily nutrition component demand information represented by the target data. For example, the server 104 can recommend the food information to the terminal device 101 or 102, and the terminal device will receive this information for external display.

[0024] It should be understood that Figure 1 The number of terminal devices and servers in the embodiment is only for illustration. Any number of terminal devices and servers may be provided according to implementation requirements.

[0025] Continue to refer Figure 2 , Figure 2 The process 200 of some embodiments of the method for evaluating nutritional intake of hemodialysis patients according to the present application is shown. The method for evaluating nutritional intake of hemodialysis patients comprises the following steps:

[0026] Step S201, obtaining individual basic information and laboratory test result information of the dialysis patient. In this embodiment, the individual basic information here includes age information, gender information, height information, dry weight information and labor intensity information.

[0027] In the actual implementation process, the individual basic information of the dialysis patient can be obtained in the following ways, such as outputting an interactive interface for collecting individual basic information through a terminal device to guide the user to enter the corresponding individual basic information in the interactive interface, and then receiving the input information of the user in the interactive interface, and obtaining the individual basic information based on the input information; Regarding the labor intensity information in the individual basic information, it should be noted that in this application, the relevant level division description is clearly displayed on the interactive interface, and the user selects the corresponding level label to realize the input, and the level division rule is based on the degree of physical exertion of the worker at work. For example, the grading rules used in this embodiment are as follows: Very light physical labor, jobs that mainly require sitting, such as office work, have relatively low labor intensity and low energy consumption; light physical labor, jobs that mainly require standing or a small amount of walking, such as teachers, salespersons, etc., have moderate labor intensity and slightly higher energy consumption than very light physical labor; medium physical labor, such as students' daily activities, certain factory operations, etc., have high labor intensity and require more energy; heavy physical labor, such as sports, mechanized agricultural labor, etc., have very high labor intensity and require a lot of energy; extremely heavy physical labor: such as certain heavy industrial labor, etc., have the most intense labor intensity and extremely high energy consumption.

[0028] Further, regarding the laboratory test result information, in the technical scenario of the present application, it can be obtained based on the following methods: by arranging a relevant human biometric sensing device on the terminal device side to sense the user's human biometric information, and then in the device background, in response to the received human biometric information, based on the biometric recognition technology, query and match in the user account database according to the human biometric information; if the match is successful, pull the identity information from the user account data corresponding to the identity authentication information; obtain the laboratory test result information from the hospital information system according to the identity information; For example, in order to ensure user experience and technical maturity, as a specific implementation method, face recognition technology can be used, and an image acquisition device can be arranged on the terminal device side. The image acquisition device is arranged in a position so that it can capture the user's face, such as near the display screen of the terminal device, and its shooting field of view direction is the same as the display direction of the display screen; in terms of control implementation, it is configured to trigger the start of image acquisition when the interactive interface for collecting basic information of the individual appears, and trigger the stop of image acquisition when the user completes the input and submits the information.

[0029] In this embodiment, if Figure 2 As shown, on the basis of step S201, step S202 is performed to calculate and generate intermediate data representing the daily nutritional component requirement information of the patient based on the individual basic information and the preset medical recommendation standard rules; As known to those skilled in the art, in existing clinical nutrition research, there are medical recommendations for nutritional requirements, such as the relevant nutritional component calculation and evaluation content involved in the "American Kidney Disease Outcome Quality Guidelines". This application constructs and sets calculation rules based on such recommendations, and then calculates and obtains intermediate data representing the daily nutritional component requirement information of the patient based on these rules and the basic personal information of the individual patient; Specifically, as a specific implementation method, Figure 3As shown, the process 300 of calculating and generating intermediate data representing the daily nutritional component requirement information of the patient specifically includes: Step S301, calculate and determine the body mass index information based on the height information and dry weight information, and calculate and determine the standard weight information based on the age information, gender information, and height information. The calculation logic here is similar to the prior art, such as body mass index = (dry weight / height squared) (kg / m 2 ), standard weight (kg) = height value (cm) - fixed value, where the fixed value is determined based on the age and gender of the subject, such as an adult male with a fixed value of 105, an adult female with a fixed value of 100, etc.; Then, step S302 is performed, according to the weight status level represented by the body mass index information and the nutrient consumption level represented by the labor intensity information, a matching parameter value is searched from the daily unit body weight required nutrient component requirement parameter table preset in the rule. For example, body mass index BMI=17.3kg / m 2 , whose characterization level is thinness, and the labor intensity information is light physical labor, the corresponding daily energy intake per kilogram of body weight is 35kcal, and the daily protein intake per kilogram of body weight is 1.2g, etc.; On the basis of obtaining the relevant parameter values, step S303 is performed to calculate and determine the intermediate data according to the parameter values ​​and the standard weight information. It is easy to understand that here the parameter value of the specific nutritional component is multiplied by the standard weight to obtain the intermediate data representing the patient's daily nutritional component requirement information. For example, for a patient A, the intermediate data obtained includes a daily energy requirement of 2275 kcal and a protein requirement of 78 g.

[0030] Based on step S202, Figure 2 As shown, step S203 is then performed to calculate and determine the deviation information between each inspection index value and the index control value based on the laboratory inspection result information, and the intermediate data is adjusted and processed based on the deviation information of the first category of indicators in the deviation information to obtain the processed target data. In this embodiment, the types of the first category of indicators in the laboratory inspection result information here include ferritin, hemoglobin and albumin.

[0031] It should be noted that, in the process of implementing the technical solution of the present application, the inventors found that some medical biochemical indicators are related to nutritional intake. For individual patients, the nutritional intake can be corrected based on the situation of such indicators so that the nutritional intake of patients is more in line with individual needs; and in the hemodialysis treatment scenario, during the dialysis treatment of patients, it is necessary to regularly check and test relevant biochemical indicators to monitor their health status, such as monitoring some biochemical indicators in the management of dialysis complications; Based on this, the applicant compared and analyzed the quality control items related to the management of dialysis complications and these indicators, and selected the first type of indicators as above from the common indicators of the two. For example, the types of the first type of indicators here include ferritin, hemoglobin and albumin; in this way, when implementing the technical solution of the present application, there is no need to carry out additional related monitoring and testing, which is more convenient for the development and promotion of the technical solution, and is also conducive to the quality control management of related complications, thereby ensuring the stability and continuity of the overall dialysis treatment effect; It should be noted that the index control values ​​of the corresponding indicators here are selected and confirmed based on relevant quality control requirements. For example, the hemoglobin index control value is 110~120g / L, the albumin index control value is 35~40g / L, etc.

[0032] Specifically, as a specific implementation method, the intermediate data is adjusted based on the deviation information of the first type of indicators in the deviation information, including: adjusting the protein requirement in the intermediate data based on the following expression: (1) In expression (1), represents the adjusted protein requirement, represents the protein requirement before adjustment, represents the deviation of index i, represents the adjustment weight of indicator i, F represents the adjustment coefficient, and f represents the conversion factor.

[0033] It is easy to understand that in the above expression (1) , based on the values ​​of i, they correspond to the deviations of the ferritin, hemoglobin, and albumin indicators respectively; and it should be noted that when calculating the deviation, for the case where the indicator control value is a range value, the midpoint value of the range value is used as the standard value for the deviation calculation. For example, for hemoglobin, its standard value is 115 g / L. If the inspection indicator value is 110g / L, the deviation is -5.

[0034] The adjustment coefficient in the expression is a constant used to control the magnitude of the adjustment. For example, in some scenarios, the adjustment coefficient is 0.5. The conversion factor refers to the protein unit corresponding to the adjusted unit. The product of the deviation and the weight is 1, which represents 1 adjusted unit. The value of the conversion factor can be determined based on relevant retrospective studies, such as 1 adjusted unit corresponds to 1g of protein. The adjustment weight in the above expression reflects the importance of each indicator in protein intake management. The value of the adjustment weight here can be determined based on expert opinion.

[0035] Furthermore, in order to ensure the consistency of expert opinions, the adjustment weights of the indicators in the above expression are pre-determined using the hierarchical analysis method. To facilitate understanding of the technical solution of the present application, the hierarchical analysis method is briefly introduced here in combination with the actual process: First, a hierarchical structure is constructed: the target layer is used to determine the goal of decision-making, such as "adjusting the protein intake of dialysis patients", the criterion layer: to determine the various biochemical indicators that affect the goal, such as ferritin, hemoglobin, albumin, etc., the solution layer: specific adjustment plans or measures, here is the weight distribution; After that, a judgment matrix was established. Relevant experts were used to compare each pair of criteria, using a 1-9 scale to indicate the degree of importance. For example, if ferritin is considered more important than hemoglobin, the comparison value of ferritin to hemoglobin in the judgment matrix can be 3, otherwise it can be 1 / 3; Then calculate the weight vector and perform consistency check on the judgment matrix to ensure the consistency of judgment, such as using the geometric mean method to calculate the weight vector; perform consistency check, that is, calculate the consistency ratio (CR) to ensure the consistency of the judgment matrix. The CR should be less than 0.10, otherwise the judgment matrix needs to be re-evaluated; When the consistency check passes, the final weight distribution is determined according to the corresponding weight vector.

[0036] For example, in one embodiment, the analytic hierarchy process is used and the final result determined based on the opinions of multiple experts is that the adjustment weight corresponding to ferritin is 0.116, the adjustment weight corresponding to hemoglobin is 0.342, and the adjustment weight corresponding to albumin is 0.542.

[0037] After step S203, proceed to step S204 to output recommended food based on the daily nutritional component requirement information represented by the target data; In this step, based on the information on daily nutritional component requirements, food recommendations can be made based on the food exchange method. For example, for a patient B, the corresponding daily nutritional component requirement information is 2275kcal energy and 78g protein. According to the predetermined energy supply ratio, carbohydrate energy supply accounts for 50%, which is 1138kcal, and fat energy supply accounts for 35%, which is 796kcal. Taking 90kcal as 1 portion, the daily food distribution is approximately: 13 portions of staple food, 1 portion of vegetables, 1 portion of fruit, 2 portions of milk, 1 egg, 3 portions of meat, 1 portion of soy products, and 3 portions of vegetable oil. The specific relevant principle details of the food exchange method can be found in existing public technical information, and this application will not elaborate on this here.

[0038] In the treatment of hemodialysis patients, some trace element indicators are also factors that need to be monitored, and some foods need to be restricted, such as high-phosphorus and high-potassium foods. However, the results obtained by directly applying the food exchange method cannot reflect this point. In view of this, based on the above embodiment, in a specific implementation method, food recommendation information is output based on the daily nutrient component requirement information represented by the target data, specifically including: Based on the daily nutrient component requirement information represented by the target data, a number of candidate food combinations are generated, and the candidate food combinations are screened based on the deviation information of the second type of indicators in the deviation information, and food recommendation information is generated and outputted according to the screened food combinations, wherein the types of the second type of indicators in the laboratory test result information include blood potassium, blood phosphorus and parathyroid hormone; In the above process, the food exchange method can also be used to distribute food, and then based on the distribution situation, the food type list corresponding to the built-in food category is called to generate several candidate food combinations that meet the distribution situation, and then the food combination is screened according to the deviation of blood potassium, blood phosphorus and parathyroid hormone (which is related to phosphorus intake). For example, for hemodialysis patients, the control index of blood potassium is 4.0~5.0mmol / L, the control index of blood phosphorus is 1.13~1.78mmol / L, and the control index of parathyroid hormone is 10 to 65pg / mL. The middle value of the range is also used as the standard value for deviation calculation, and then the corresponding food is screened based on the positive and negative situation of the deviation. For example, when the blood potassium deviation is positive, the food combination containing high potassium food is excluded, and if the deviation is negative, no screening process is performed; and for the deviation of parathyroid hormone and blood phosphorus, both correspond to phosphorus-containing foods. As long as one of the deviations is positive, the high phosphorus food is excluded, and if the deviation is negative, no screening process is performed; It should be noted that the process of determining high-potassium or high-phosphorus foods here is to analyze the food combination to be selected, calculate the trace elements of the food in the combination according to the preset unit content value table of trace elements in food, and use the food with the highest calculated result among the same type of food as the high-potassium or high-phosphorus food in this screening process. In this way, while ensuring the output of recommended results, the recommended results can better meet the needs of individual patients.
