Summary of the Invention

Problems to be Solved by the Invention

[0004] Drugs taken to treat a disease may cause adverse reactions. In order to concentrate medical resources on the main interventional medical procedures without causing adverse reactions, it is important to know the signs of adverse reactions at an early stage. However, the diagnostic support device of Patent Document 1 exclusively uses examination data as a criterion for determining the presence or absence of a disease, and lacks the idea of estimating unknown adverse reactions based on the answers to the interview about the current interventional medical procedures being received. Therefore, an object of the present invention is to know unknown adverse reactions based on the answers to an interview.

Means for Solving the Problems

[0005] The interview assistance device of the present invention is provided with a risk determination unit that determines the degree of a harmful reaction risk, which is the risk of a harmful reaction occurring during the interventional medical act, for each of the harmful reactions based on the response from the patient obtained in the interview regarding the interventional medical act for the disease the patient is suffering from. e , The risk determination unit refers to response information in which combinations of the interview, the responses to the interview, and the adverse reaction risk estimation values are hierarchically stored according to the order of the interview, and determines the degree of the adverse reaction risk based on some or all of the adverse reaction risk estimation values included in the combination through which the patient has passed. and is characterized by the above. Other means will be described in the mode for carrying out the invention.

Effect of the Invention

[0006] According to the present invention, an unknown harmful reaction can be known based on the response to the interview.

Mode for Carrying Out the Invention

[0008] Hereinafter, a mode for carrying out the present invention (referred to as "this embodiment") will be described in detail with reference to the drawings and the like. In this embodiment, the patient answers an interview regarding an interventional medical act for curing the currently suffering disease. Then, the interview assistance device determines an adverse reaction together with the degree of the adverse reaction risk.

[0009] (Terms, etc.) An interventional medical act is, in addition to pharmaceuticals, a treatment such as radiation therapy, surgery, etc. or a combined therapy thereof. An adverse reaction is any undesirable or unintended sign (e.g., abnormal clinical test values), symptom, or disease that occurs in a patient who has received an interventional medical act, is temporally related, and the causal relationship with the interventional medical act cannot be denied.

[0010] An adverse reaction risk is the possibility of an adverse reaction occurring or the risk that an adverse reaction poses to a patient. The adverse reaction risk is also shown by the degree of the adverse reaction risk by being relatively quantified. The existence of an adverse reaction risk may be evaluated by an absolute numerical value or may be evaluated by a binary value such as "present" or "absent" (details will be described later). An adverse reaction risk estimated value is a value that serves as a basis for determining an adverse reaction risk and is associated with an interview and its answer (details will be described later).

[0011] One or more interviews correspond to a combination of an interventional medical act and an adverse reaction. For example, for a patient who is known to be suffering from the disease "stomach cancer" and is undergoing "drug therapy" as an interventional medical act, one or more interviews correspond to detecting the adverse reaction "hand-foot syndrome". An answer is a reply to an interview. The answer may be "yes" or "no", or may be other words or numerical values. That is, a plurality of answer options correspond to one interview. For a combination of a certain inquiry and its answer, there is one corresponding next inquiry. That is, the inquiry and the answer constitute a hierarchical tree structure by repeating the root inquiry, the branching answer, and further the leaf inquiry at the end of the branch, the necessary number of times.

[0012] (Configuration, etc. of the Inquiry Assistance Device) Figure 1 is a diagram for explaining the configuration, etc. of the inquiry assistance device 1. The inquiry assistance device 1 is a general computer and includes a central control device 11, an input device 12 such as a mouse and a keyboard, an output device 13 such as a display, a main memory device 14, an auxiliary memory device 15, and a communication device 16. These are interconnected by a bus. The auxiliary memory device 15 stores patient information 31, adverse reaction information 32, inquiry information 33, answer information 34, related adverse reaction information 35, and examination information 36 (details will be described later).

[0013] The input / output processing unit 21 and the risk determination unit 22 in the main memory device 14 are programs. The central control device 11 realizes the functions of the respective programs (details will be described later) by reading these programs from the auxiliary memory device 15 into the main memory device 14.

[0014] The inquiry assistance device 1 is connected to the patient terminal device 2, the medical staff terminal device 3, and the external storage device 4 via a wired or wireless network 5. The patient operates the patient terminal device 2. The medical staff operates the medical staff terminal device 3. The external storage device 4 is an arbitrary device for data storage. Part or all of each of the information 31 to 36 stored in the auxiliary memory device 15 in FIG. 1, and part or all of each of the programs 21 and 22 read into the main memory device 14 may be stored dispersedly in the patient terminal device 2, the medical staff terminal device 3, or the external storage device 4. The inquiry assistance device 1 and the patient terminal device 2 constitute an inquiry assistance system.

[0015] (Patient Information) Figure 2 shows an example of patient information 31. In the patient information 31, associated with the patient ID stored in the patient ID column 101, the start date is stored in the start date column 102, the end date is stored in the end date column 103, the name of the interventional medical procedure is stored in the interventional medical procedure name column 104, and the name of the medical department is stored in the medical department name column 105. The patient ID in the patient ID column 101 is an identifier that uniquely identifies the patient. The start date in the start date column 102 is the year, month, and day when the interventional medical procedure for the patient was started, or the year, month, and day when the patient became a user of the service by the inquiry assistance device 1. The end date in the end date column 103 is the year, month, and day when the interventional medical procedure for the patient is scheduled to end, or the year, month, and day when the patient is scheduled to be removed as a user of the service by the inquiry assistance device 1. The name of the interventional medical procedure in the interventional medical procedure name column 104 is the name of the interventional medical procedure described above. The name of the medical department in the medical department name column 105 is the name of the medical department to which the disease belongs (such as the Department of Cardiology, Department of Gastroenterology, Department of Urology, etc.).

[0016] (Adverse reaction information) Figure 3 shows an example of adverse reaction information 32. In the adverse reaction information 32, associated with the name of the interventional medical procedure stored in the interventional medical procedure name column 111, the adverse reaction ID is stored in the adverse reaction ID column 112, the inquiry ID is stored in the inquiry ID column 113, and the name of the adverse reaction is stored in the adverse reaction name column 114. The name of the interventional medical procedure in the interventional medical procedure name column 111 is the same as the name of the interventional medical procedure in Figure 2. The adverse reaction ID in the adverse reaction ID column 112 is an identifier that uniquely identifies the adverse reaction described above. The inquiry in the inquiry ID column 113 is an identifier that uniquely identifies the inquiry described above. The name of the adverse reaction in the adverse reaction name column 114 is the name of the adverse reaction described above.

[0017] As is clear from FIG. 3, in the example of FIG. 3, a plurality of adverse reactions correspond to one interventional medical act. A plurality of inquiries correspond to one adverse reaction. For the plurality of inquiries corresponding to one adverse reaction, the order in which they are displayed to the patient is predefined. The inquiries are displayed in ascending order of the last three digits of the inquiry ID.

[0018] (Inquiry information) FIG. 4 is an example of inquiry information 33. In the inquiry information 33, in association with the inquiry ID stored in the inquiry ID column 121, the inquiry is stored in the inquiry column 122. The inquiry ID in the inquiry ID column 121 is the same as the inquiry ID in FIG. 3. The inquiry in the inquiry column 122 is a character string in natural language indicating the above-mentioned inquiry. A separate file representing the inquiry as an audio waveform may be stored in association with the inquiry ID.

[0019] As is clear from FIGS. 3 and 4, for example, three inquiries correspond to the adverse reaction name "obliterative neuropathy". Four inquiries correspond to the adverse reaction name "hand-foot syndrome". Four inquiries correspond to the adverse reaction name "constipation".

[0020] (Answer information) FIG. 5 is an example of answer information 34. In the answer information 34, in association with the inquiry ID stored in the inquiry ID column 131, the answer ID is stored in the answer ID column 132, the adverse reaction risk estimated value is stored in the adverse reaction risk estimated value column 133, and the answer is stored in the answer column 134. The inquiry ID in the inquiry ID column 131 is the same as the inquiry ID in FIG. 3. The answer ID in the answer ID column 132 is an identifier that uniquely identifies the option among the plurality of answer options for the same inquiry.

[0021] The adverse reaction risk estimated value in the adverse reaction risk estimated value column 133 is the above-mentioned adverse reaction risk estimated value, and the adverse reaction risk estimated value is also the degree (relative value) of the adverse reaction risk. As described above, while the adverse reaction risk is defined for the adverse reaction, the adverse reaction risk estimated value is associated with the combination of the inquiry and its answer. The response in response column 134 is the above-mentioned response. A separate file representing the response as an image may be stored in association with the response ID.

[0022] Subsequently, an example of the process in which the medical interview assistance device 1 determines the degree of the adverse reaction risk according to the response to the medical interview is described below. 〈1〉 As a process for determining the adverse reaction risk of adverse reaction F001 “ablation neuropathy”, assume that the input / output processing unit 21 displays the medical interview Q001 “Have you had any problems with your hands, feet, throat, ···?” to the patient, and accepts the patient's input of response A01 “No”. In this case, the risk determination unit 22 determines that the adverse reaction risk is “0” (the same as the adverse reaction risk estimated value in record 135a of FIG. 5).

[0023] 〈2〉 As a process for determining the adverse reaction risk of adverse reaction F001 “ablation neuropathy”, assume that the input / output processing unit 21 displays the medical interview Q001 “Have you had any problems with your hands, feet, throat, ···?” to the patient, and accepts the patient's input of response A02 “Yes”. In response to this response, assume that the input / output processing unit 21 displays the medical interview Q002 “Have you had any discomfort or numbness ···?” to the patient, and accepts the patient's input of response A01 “No”. In this case, the risk determination unit 22 determines that the adverse reaction risk is “1” (the same as the adverse reaction risk estimated value in record 135b of FIG. 5).

[0024] 〈3〉 As a process for determining the adverse reaction risk of adverse reaction F001 “ablation neuropathy”, assume that the input / output processing unit 21 displays the medical interview Q001 “Have you had any problems with your hands, feet, throat, ···?” to the patient, and accepts the patient's input of response A02 “Yes”. In response to this response, assume that the input / output processing unit 21 displays the medical interview Q002 “Have you had any discomfort or numbness ···?” to the patient, and accepts the patient's input of response A02 “Yes”. In response to this answer, it is assumed that the input / output processing unit 21 displays the inquiry Q003 "Did you have... with chopsticks?" to the patient and accepts the patient's input of the answer A01 "No". In this case, the risk determination unit 22 determines that the adverse reaction risk is "2" (the same as the adverse reaction risk estimated value in record 135c of FIG. 5).

[0025] 〈11〉As a process for determining the adverse reaction risk of the adverse reaction F002 "hand-foot syndrome", it is assumed that the input / output processing unit 21 displays the inquiry Q011 "Regarding the symptoms of the hands,... Which one is it?" to the patient and accepts the patient's input of the answer A01 "Naked skin or...". In response to this answer, it is assumed that the input / output processing unit 21 displays the inquiry Q012 "When taking a bath, did you have... with hot water?" to the patient and accepts the patient's input of the answer A02 "It has been painful".

[0026] In response to this answer, it is assumed that the input / output processing unit 21 displays the inquiry Q013 "When opening a book,... did you have...?" to the patient and accepts the patient's input of the answer A03 "Opening the book due to pain...". In response to this answer, it is assumed that the input / output processing unit 21 displays the inquiry Q014 "Compared to before,... did you have...?" to the patient and accepts the patient's input of the answer A02 "There is a sense of discomfort". In this case, the risk determination unit 22 determines that the adverse reaction risk is "3". This "3" is the maximum among the adverse reaction risk estimated values of records 136a to 136d passed through in FIG. 5.

[0027] 〈31〉As a process for determining the adverse reaction risk of the adverse reaction F003 "constipation", it is assumed that the input / output processing unit 21 displays the inquiry Q021 "Do you have a bowel movement every day?" to the patient and accepts the patient's input of the answer A01 "Yes". In this case, the risk determination unit 22 determines that the adverse reaction risk is "0" (the same as the adverse reaction risk estimated value in record 137a of FIG. 5).

[0028] 〈32〉As a process for determining the risk of the adverse reaction F003 "constipation", assume that the input / output processing unit 21 displays the inquiry Q021 "Do you have a bowel movement every day?" to the patient and accepts the patient's input of the answer A02 "There are days when I don't...". In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q022 "How many consecutive days have you not had a bowel movement?" to the patient and accepts the patient's input of the answer A02 "3 to 5 days".

[0029] In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q023 "Have you taken laxatives for constipation?" to the patient and accepts the patient's input of the answer A02 "I have taken them 1 to 3 times". In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q024 "Did you have a bowel movement after taking the medicine?" to the patient and accepts the patient's input of the answer A01 "Yes". In this case, the risk determination unit 22 determines that the adverse reaction risk is "2". This "2" is the maximum of the adverse reaction risk estimated values of the records 137b to 137e passed through in FIG. 5.

[0030] 〈33〉As a process for determining the risk of the adverse reaction F003 "constipation", assume that the input / output processing unit 21 displays the inquiry Q021 "Do you have a bowel movement every day?" to the patient and accepts the patient's input of the answer A02 "There are days when I don't...". In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q022 "How many consecutive days have you not had a bowel movement?" to the patient and accepts the patient's input of the answer A03 "6 days or more".

[0031] In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q023 "Have you taken laxatives for constipation?" to the patient and accepts the patient's input of the answer A02 "I have taken them 1 to 3 times". In response to this answer, assume that the input / output processing unit 21 displays the inquiry Q024 "Did you have a bowel movement after taking the medicine?" to the patient and accepts the patient's input of the answer A02 "No". In this case, the risk determination unit 22 determines that the adverse reaction risk is "3" (the same as the adverse reaction risk estimated value in record 137f of FIG. 5). Record 137f is a special provision dummy record, which indicates that when the patient inputs answer A03 "more than 6 days" to inquiry Q022 and inputs answer A02 "no" to inquiry Q024, the adverse reaction risk becomes "3".

[0032] As is clear from the above, although not shown in the figure, the auxiliary storage device 15 stores risk rules that define the following. · For which inquiry and which answer, which next inquiry to proceed to · For which inquiry and which answer, the inquiry ends · Based on the adverse reaction risk estimated value corresponding to which combination among the combinations of inquiries and answers passed through, how to determine the final adverse reaction risk Ultimately, the risk determination unit 22 of the inquiry assistance device 1 refers to the response information 34 in which the combinations of inquiries, answers, and adverse reaction risk estimated values are hierarchically stored according to the order of the inquiries, and determines the degree of the adverse reaction risk based on some or all of the adverse reaction risk estimated values included in the combination passed through by the patient.

[0033] (Related Adverse Reaction Information) FIG. 6 is an example of the related adverse reaction information 35. In the related adverse reaction information 35, in association with the name of the interventional medical act stored in the interventional medical act name column 141, the adverse reaction ID is stored in the adverse reaction ID column 142, the risk expression is stored in the risk expression column 143, the condition is stored in the condition column 144, and the adverse reaction name is stored in the adverse reaction name column 145.

[0034] The name of the interventional medical act in the interventional medical act name column 141 is the same as the name of the interventional medical act in FIG. 2. The adverse reaction ID in the adverse reaction ID column 142 is the same as the adverse reaction ID in FIG. 3. The risk expressions in the risk expression column 143 are the ways to represent the degree of the adverse reaction risk. Among them, "relative value" indicates that the adverse reaction risk is expressed by a relative value (for example, "1" to "3"). "Absolute value" indicates that the adverse reaction risk is expressed by an absolute value (for example, the reading of a sphygmomanometer itself). "Binary (yes, no)" indicates that the adverse reaction risk is expressed as "yes" or "no".

[0035] The conditions in the condition column 144 are conditional expressions of logical sum or logical product for estimating the said adverse reaction risk based on one or more other adverse reaction risks. There may be cases where there are no conditions corresponding to the adverse reaction (details will be described later). The adverse reaction names in the adverse reaction name column 145 are the same as the adverse reaction names in Figure 3.

[0036] For example, record 146 in Figure 6 shows the following. · It is known that the patient has received the interventional medical procedure a. · As a result of the interview and answers, it was found that the patient has adverse reaction risks of adverse reaction F001 "obliterative neuropathy", adverse reaction F002 "hand-foot syndrome", and adverse reaction F004 "anorexia". · However, it is difficult to directly predict from the results of the interview and answers that the adverse reaction F007 "hypothyroidism" will occur. · At this time, when the adverse reaction risk of adverse reaction F001 "obliterative neuropathy" is 2 or more and the adverse reaction risk of adverse reaction F002 "hand-foot syndrome" is 1 or more, the adverse reaction risk of adverse reaction F007 "hypothyroidism" is presumed to be "yes".

[0037] Similarly, record 147 shows the following. · It is known that the patient has received the interventional medical procedure a. · As a result of the interview and answers, it was found that the patient has adverse reaction risks of adverse reaction F008 "fatigue" and adverse reaction F004 "anorexia". ·As a result of the examination (details will be described later), it was found that the patient has a risk of adverse reaction F009 "high TSH value". ·However, it is difficult to directly predict from the results of the examination, interview, and response that adverse reaction F007 "hypothyroidism" will occur. ·At this time, when the risk of adverse reaction F008 "fatigue" is 2 or more, and the risk of adverse reaction F004 "loss of appetite" is "present", and the risk of adverse reaction F009 "high TSH value" is 2 or more, the risk of adverse reaction F007 "hypothyroidism" is presumed to be "present".

[0038] As is clear from the above, the interview support device 1 can estimate the risk of adverse reactions that cannot be directly derived from the results of the examination, interview, and response based on other known risks of adverse reactions. In FIG. 6, the condition column 144 of the record of F001 "abraded nerve disorder" is blank. This indicates that it is difficult to estimate "abraded nerve disorder" based on other adverse reactions unless it can be directly derived from the results of the examination, interview, and response.

[0039] (Examination information) FIG. 7 shows an example of examination information 36. In the examination information 36, associated with the examination target stored in the examination target column 151, the gender is stored in the gender column 152, the risk of adverse reaction is stored in the adverse reaction risk column 153, the unit is stored in the unit column 154, the minimum value is stored in the minimum value column 155, and the maximum value is stored in the maximum value column 156. The examination target in the examination target column 151 is the type of biological information of the patient known through the examination. Before and after the interview, medical staff perform an examination on the patient. Different from the interview, in the examination, the biological information of the patient is acquired through a contact-type or non-contact-type instrument. Or, the specimen obtained from the patient is analyzed. For example, the examination target corresponds to the adverse reaction name, such as "neutrophil concentration" corresponding to "neutropenia".

[0040] The gender in the gender column 152 is the gender of the patient. The adverse reaction risk in the adverse reaction risk column 153 is the adverse reaction risk corresponding to the test subject. The unit in the unit column 154 is the unit of the biological information that is the test subject. The minimum value in the minimum value column 155 is the lower limit of the range of values of the biological information corresponding to that adverse reaction risk. "#" indicates different numerical values in an abbreviated manner (the same applies hereinafter). The maximum value in the maximum value column 156 is the upper limit of the range of values of the biological information corresponding to that adverse reaction risk. For example, when the neutrophil concentration as the test result is "700", the adverse reaction risk of adverse reaction F006 "neutropenia" (Figure 6) is "3".

[0041] (Test result) The auxiliary storage device 15 stores the test results (not shown). The test results are a set of combinations of patient ID, test execution date, test subject, and the measured / analyzed value of the test subject.

[0042] (Processing procedure) Hereinafter, the processing procedure of this embodiment will be described. As a prerequisite for starting the processing procedure, patient information 31 (Figure 2), adverse reaction information 32 (Figure 3), interview information 33 (Figure 4), response information 34 (Figure 5), related adverse reaction information 35 (Figure 6), and test information (Figure 7) are stored in the auxiliary storage device 15 in a completed state.

[0043] Figure 8 is a flowchart of the processing procedure. Appropriate drawings will be referred to during the description of the flowchart. In step S201, the input / output processing unit 21 of the interview assistance device 1 receives the patient ID. Specifically, first, the input / output processing unit 21 ensures communication with the patient terminal device 2. Second, the input / output processing unit 21 receives the patient's input of the patient ID to the patient terminal device 2.

[0044] In step S202, the risk determination unit 22 of the interview assistance device 1 acquires the name of the interventional medical procedure. Specifically, the risk determination unit 22 searches for the patient information 31 (Fig. 2) using the patient ID received in "Second" of step S201 as a search key, and acquires the name of the interventional medical procedure in the corresponding record. For the sake of convenience of explanation, it is assumed here that "interventional medical procedure a" has been acquired.

[0045] In step S203, the risk determination unit 22 acquires candidates for adverse reactions. Specifically, the risk determination unit 22 searches for the adverse reaction information 32 (Fig. 3) using "interventional medical procedure a" as a search key, and acquires the adverse reaction IDs in the corresponding records. Here, "F001", "F002", "F003" and "F004" will be acquired.

[0046] In step S204, the risk determination unit 22 acquires the interview to be displayed. Specifically, first, the risk determination unit 22 acquires any unprocessed adverse reaction ID among the adverse reaction IDs acquired in step S203. For the sake of convenience of explanation, it is assumed here that "F001" has been acquired. Second, the risk determination unit 22 searches for the adverse reaction information 32 using "F001" as a search key, and acquires all the interview IDs in the corresponding records. Here, "Q001", "Q002" and "Q003" are acquired.

[0047] In step S205, the input / output processing unit 21 of the interview assistance device 1 displays the interview. Specifically, first, the input / output processing unit 21 searches for the interview information 33 (Fig. 4) using the earliest-ordered "Q001" as a search key, and acquires the interview in the corresponding record. Here, the interview "Have you had hands, feet, throat...?" is acquired. Second, the input / output processing unit 21 displays the interview / answer screen 41 (Fig. 9, detailed later) on the patient terminal device 2, displays the interview "Have you had hands, feet, throat...?" in the interview column 42, and also outputs the voice of that interview.

[0048] In step S206, the input / output processing unit 21 displays answer options. Specifically, first, the input / output processing unit 21 searches for answer information 34 (Fig. 5) using "Q001" as a search key, and acquires all the answers in the corresponding records. Here, the answers "none" and "present" are acquired. Second, the input / output processing unit 21 displays the answers "none" and "present" as options in answer fields 43a and 43b of the interview / answer screen 41 in Fig. 9. Although it is in the middle of the flowchart, the explanation will move to Fig. 9 once.

[0049] Fig. 9 is an example of the interview / answer screen 41. The input / output processing unit 21 displays an interview in the interview field 42 and displays answer options in answer fields 43a and 43b. The input / output processing unit 21 may display an image (such as an image of the part of the body where a harmful reaction has occurred) in answer fields 43a and 43b. When the patient presses the "Back" button 45 on the interview / answer screen 41, the input / output processing unit 21 returns the screen to the previous interview. When the patient selects one of the answer buttons 44a or 44b and then presses the "Next" button 46, the input / output processing unit 21 advances the screen to the next interview. The input / output processing unit 21 displays, in the band graph 47, the estimated time from when the first answer is displayed until the answer to the last interview ends, and the elapsed time until now. The band graph 47 may be the ratio of the number of completed interviews to the total number of all interviews. The explanation returns to Fig. 8.

[0050] In step S207, the input / output processing unit 21 accepts an answer. Specifically, the input / output processing unit 21 accepts that the patient selects one of the answer buttons 44a or 44b and then presses the "Next" button 46.

[0051] The processes in steps S205 to S207 are repeated for each interview whose display order was pre-planned (inner loop). The processes in steps S204 to S207 are repeated for all of the harmful reaction IDs "F001", "F002", "F003", and "F004" (outer loop).

[0052] In step S208, the risk determination unit 22 of the interview assistance device 1 acquires the examination information 36 (Fig. 7) and the examination results. Specifically, the risk determination unit 22 acquires the examination information 36 and the examination results from the auxiliary storage device 15.

[0053] In step S209, the risk determination unit 22 determines the risk of adverse reactions. Specifically, the risk determination unit 22 determines the degree of the risk of all adverse reactions F001, F002, F003, and F004 (for example, relative numerical values from "1" to "3") by the method described above in the description of Fig. 5.

[0054] In step S210, the risk determination unit 22 determines the risk of adverse reactions of related adverse reactions. Specifically, the risk determination unit 22 determines the degree of the risk of adverse reactions of other adverse reactions other than the adverse reactions F001, F002, F003, and F004 (for example, two values of "yes" and "no") by the method described above in the description of Fig. 6. Here, for the sake of convenience of explanation, it is assumed that the risk determination unit 22 estimates that the risk of the adverse reaction F007 "hypothyroidism" is "yes" based on the risk of the adverse reactions F001, F002, F003, and F004.

[0055] In step S211, the risk determination unit 22 rearranges the adverse reactions in the order of the risk of adverse reactions. Specifically, the risk determination unit 22 rearranges the risks of the adverse reactions and related adverse reactions determined in steps S209 and S210 according to the following rearrangement rules. · The one with a larger relative numerical value of the risk of adverse reaction is ranked higher. · When the relative numerical values of the risks of adverse reactions are the same, the one with a larger rising width in time series is ranked higher. · Those with a binary value of "yes" for the risk of adverse reaction are ranked lower. · Those with a relative numerical value of "0" for the risk of adverse reaction are excluded from the objects of rearrangement.

[0056] For example, it is assumed that the risks of the following four adverse reactions or related adverse reactions are known. · Adverse reaction F001 "Erased neuropathy": Previous adverse reaction risk "2" → Current adverse reaction risk "3" · Adverse reaction F002 "Hand-foot syndrome": Previous adverse reaction risk "1" → Current adverse reaction risk "3" · Adverse reaction F003 "Constipation": Current adverse reaction risk "2" · Adverse reaction F004 "Loss of appetite": Current adverse reaction risk "0" · Related adverse reaction F007 "Abdominal pain": Current adverse reaction risk "Yes" In this case, the risk determination unit 22 will arrange the adverse reaction risks in the order of "hand-foot syndrome, erased neuropathy, constipation, abdominal pain".

[0057] In step S212, the input / output processing unit 21 of the interview assistance device 1 displays the adverse reaction and the adverse reaction risk. Specifically, the input / output processing unit 21 displays the warning screen 51 (Figure 10) on the output device 13 or the medical staff terminal device 3. Although it is in the middle of the flowchart, the explanation will move to Figure 10 once.

[0058] Figure 10 is an example of the warning screen 51. The input / output processing unit 21 displays the patient name in the patient name column 52 and the known interventional medical act name in the interventional medical act name column 53. The input / output processing unit 21 displays the adverse reaction in the adverse reaction column 54 and the adverse reaction risk in the adverse reaction risk column 55. At this time, the input / output processing unit 21 displays the adverse reactions in the order sorted in step S211. If there is no adverse reaction risk for the patient (for example, the adverse reaction risks of all candidates are "0"), the input / output processing unit 21 may display the text "There is no adverse reaction risk for this patient" in the adverse reaction column 54. The explanation returns to Figure 8.

[0059] In step S213, the input / output processing unit 21 displays the examination results and the interview results. Specifically, first, the input / output processing unit 21 accepts the medical staff's selection of a specific patient name (column 52 in Figure 10). For the convenience of explanation, it is assumed here that "Taro Hitachi" is selected. Second, the input / output processing unit 21 displays the examination result / questionnaire result screen 61 (Fig. 11) on the output device 13 or the medical staff terminal device 3. Although it is in the middle of the flowchart, the explanation will move to Fig. 11 once.

[0060] Fig. 11 is an example of the examination result / questionnaire result screen 61. The input / output processing unit 21 displays the examination results and questionnaire results regarding "Taro Hitachi" in the column 62. The warning screen 51 (Fig. 10) displays harmful reactions that particularly require the attention of medical staff. In contrast, the examination result / questionnaire result screen 61 displays all the candidate harmful reactions, including "diarrhea" for which it has been found that there is no harmful reaction risk as a result. The ★ indicates that the harmful reaction risk is greater than a predetermined standard. When the input / output processing unit 21 accepts the selection (click) of an arbitrary harmful reaction (in Fig. 11, "vomiting") by the medical staff, it displays the questionnaire and its answers regarding that harmful reaction in the column 63. The explanation returns to Fig. 8.

[0061] In step S214, the input / output processing unit 21 displays the coping method. Specifically, first, the input / output processing unit 21 accepts the selection (double-click) of an arbitrary harmful reaction by the medical staff in the column 62 of Fig. 11. For the sake of explanation, it is assumed that "neutrophil concentration" and "platelet concentration" are selected. Second, the input / output processing unit 21 displays the coping screen 71 (Fig. 12) on the output device 13 or the medical staff terminal device 3. Although it is in the middle of the flowchart, the explanation will move to Figs. 12 and 13 once.

[0062] Figs. 12 and 13 are an example of the coping screen 71. The input / output processing unit 21 displays the coping plan, patient guidance, and guidance for medical staff regarding "neutrophil concentration" in the column 72 (Fig. 12). These pieces of information are stored in the auxiliary storage device 15 in association with the harmful reaction "neutropenia". Similarly, the input / output processing unit 21 displays the coping plan, patient guidance, and guidance for medical staff regarding "platelet concentration" in the column 73 (Fig. 12). These pieces of information are also stored in the auxiliary storage device 15 in association with the harmful reaction "thrombocytopenia".

[0063] Now, assume that a medical professional selects "neutrophil concentration" in FIG. 12. Then, the input / output processing unit 21 transitions the response screen 71 in FIG. 12 to the response screen 71 in FIG. 13. And further assume that the medical professional selects the response plan "reduce the dosage of drug b" (FIG. 13). Then, the input / output processing unit 21 displays the dosage at the time of reducing the dosage of drug b in column 74 (FIG. 13). The explanation returns to FIG. 8. After that, the processing procedure ends.

[0064] (Effects of the present embodiment) The effects of the inquiry assistance device of the present embodiment are as follows. (1) The inquiry assistance device can determine the degree of adverse reaction risk based on the inquiry and the answer. Therefore, for example, the time before a face-to-face examination can be effectively utilized. (2) The inquiry assistance device can determine the degree of adverse reaction risk based on the estimated value of adverse reaction risk associated with the answer to the inquiry sequentially displayed to the patient.
