  However, the technique described in Patent Document 1 has a technical problem that it can be applied only to diseases in which the degree of progression or the effect of treatment can be confirmed using medical images such as cancer.

  The present invention has been made in view of the above problems, for example, and an information display apparatus and method, and a computer program capable of presenting a therapeutic effect and the like predicted based on past case information regardless of disease. It is an issue to provide.

  In order to solve the above-described problem, the information display device of the present invention includes an input unit that can accept user input, and a plurality of patients when a treatment plan related to one patient is input via the input unit. With reference to a patient database that includes patient information indicating the type, condition and treatment status of each disease, the type and condition of the disease related to the one patient are specified, and the type and condition of the specified disease Cases stratified for each disease group defined by a combination of a specifying means for specifying a disease group related to the one patient according to the inputted treatment plan and a disease type, disease state, and treatment method Output means for extracting case information corresponding to the specified disease group from a case database including information and outputting a predicted value of an index corresponding to the input treatment plan. .

  According to the information display apparatus of the present invention, the input means such as a keyboard, a mouse, a touch panel, etc. is configured to accept user input.

  For example, the specifying means including a memory, a processor, and the like refers to a patient database when a treatment plan related to one patient is input through the input means, and refers to a patient type and a disease state related to the one patient. Is identified. The specifying unit further specifies a disease group related to the one patient according to the type and condition of the specified disease and the input treatment plan.

  The patient database is a database including patient information indicating the type, condition, and treatment status of a disease related to each of a plurality of patients.

  Here, the “type of disease” is defined by a disease name, a classification based on the cause (onset mechanism) of the disease, and a classification based on a disease state (stage). This “type of disease” is subdivided to the same extent as the classification in the known disease management such as the international disease classification.

  “Disease state” is not limited to symptoms that are various phenomena that occur depending on the type of disease (for example, high fever, rash, headache, etc.). For example, the condition is such that the disease is severe, mild, or critical. It is a concept that also includes The “treatment status” is not limited to the medical treatment process and treatment method, and includes, for example, a treatment period, a test value, a treatment history, and the like.

  For example, an output unit including a memory, a processor, etc. extracts case information corresponding to the specified disease group from the case database, and outputs a predicted value of an index corresponding to the input treatment plan.

  The case database is a database including case information stratified for each disease group defined by a combination of disease type, disease state, and treatment method. Here, in particular, since the disease group is defined by a combination of the disease type, disease state, and treatment method, the disease group can be defined for any disease, which is very advantageous in practice.

  In the present invention, as described above, the identifying means identifies the disease group associated with the one patient according to the type and condition of the disease associated with the one patient and the input treatment plan, and the output means identifies the disease group. Case information corresponding to the identified disease group is extracted from the case database. Therefore, according to the information display device of the present invention, it is possible to present the predicted value of the index corresponding to the treatment plan (that is, the treatment effect) to the user based on the past case information regardless of the disease.

  In one aspect of the information display apparatus of the present invention, the output means refers to the patient database, the index value corresponding to the treatment plan included in the treatment status related to the one patient, and the extracted case The predicted value is output by combining the fluctuation amount of the index corresponding to the input treatment plan included in the information.

  According to this aspect, when a treatment plan for one patient is implemented, it is possible to present to the user how the current index value related to the one patient changes, which is very practical. It is advantageous.

  In another aspect of the information display device of the present invention, the treatment plan includes a treatment method and a degree of implementation.

  According to this aspect, on the condition that each case information includes the degree of execution of treatment according to one treatment method, a change in the index corresponding to the treatment plan according to the degree of execution of treatment is performed by the user.

  An embodiment according to an information display device of the present invention will be described with reference to the drawings. In the following embodiments, a medical information system is given as an example of the information display device of the present invention.

(Configuration of medical information system)
The configuration of the medical information system 1 according to the embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating a configuration of a medical information system according to the embodiment.

  In FIG. 1, a medical information system 1 is a system in which a management server 10 and a terminal device 20 are both accommodated in a network 30. The network 30 may be a wide area network such as the Internet, or may be a narrow area network such as a LAN (Local Area Network).

  The management server 10 stores, for example, a patient profile 11 that stores basic information about a patient such as name, sex, date of birth, medical history, and allergies, and information on examination and treatment such as blood test results and medication history. The patient medical data 12 to be stored is accessible.

  The patient profile 11 and patient medical data 12 are typically the same as those in the electronic medical record system, but may be constructed as unique to the medical information system 1. The patient profile 11 and patient medical data 12 may be configured as a part of the management server 10 or may be stored in a device separate from the management server 10.

  The management server 10 is further configured to be accessible to the stratified case database 13. The stratified case database 13 is constructed by classifying (stratifying) a large number of case data into combinations of disease states and treatments for each disease classified by the cause and pathology. Details thereof will be described later.

  For example, the terminal device 20, which is a personal computer, a tablet terminal, or the like, requests information related to one patient from the management server 10 to obtain information (for example, a profile, medical information, etc.) related to the one patient. , Configured to display on the screen.

  As an example of an image displayed on the screen of the terminal device 20, for example, basic information such as a patient name, patient ID, age, sex, disease name, a graph showing a time course such as blood pressure, and the like should be noted Examples include images including index values, diagnosis results, treatment methods, medications, complications, and the like (see FIG. 2). The image shown in FIG. 2 is configured so that the user can list the status and treatment status of one patient, but the configuration of the image displayed on the screen of the terminal device 20 is not limited to this. Various aspects can be taken.

  In particular, the medical information system 1 is configured so that, for example, when a future treatment method and an implementation level of the treatment method are input, for example, prediction of a treatment effect can be presented to the user.

  Specifically, for example, when the image shown in FIG. 2 is displayed on the screen of the terminal device 20 and the button a “treatment / risk prediction” at the upper right of the image is selected by the user, The “risk prediction” screen b (see FIG. 3) is displayed on the screen.

  For example, in the case of diabetes, for example, an image as shown in FIG. 4 is displayed on the screen of the terminal device 20 as the “treatment / risk prediction” screen b. FIG. 4 is merely an example of a “treatment / risk prediction” screen, and is not related to the patient shown in FIG.

The user selects one of the current situations (for example, “None”, “Almost no implementation”, “Some implementation” and “Almost implementation” for the diet), for example, The corresponding radio button is selected) and a future plan (for example, “None”, “Almost no implementation”, “Some implementation” and “Almost implementation” is selected for diet) is selected Later, when the “prediction execution” button is pressed (selected),
Corresponding case data is extracted from the stratified case database 13 by the management server 10, and for example, treatment prediction and complication risk based on the extracted case data are displayed on the screen of the terminal device 20.

  In FIG. 4, as a treatment prediction, a prediction result when dietary therapy is performed is displayed (“None” is selected for exercise therapy, oral drug therapy, and injection drug therapy). Here, it is predicted that the “HbA1c” value will be improved from 7.5 to 7.1, the “fasting blood glucose level” from 140 to 130, and the “post-meal 2 h blood glucose level” will be improved from 280 to 220 by diet. ing.

  The percentage beside each numerical value indicates the proportion of cases in which the value of “HbA1c” is reduced by 0.4, for example, among cases related to a patient who has undergone diet therapy for a disease affecting one patient. Yes.

  In FIG. 4, the prediction result about the complication risk is displayed in addition to the treatment prediction. Further, when the “graph display” button is pressed (selected), a graph for each index value such as HbA1c is displayed on the screen (not shown).

  As described above, according to the medical information system 1, the therapeutic effect is predicted, so that it is possible to support, for example, the formulation of a treatment plan by a doctor.

(Stratified case database)
Next, explanation will be given on the stratified case database 13.

  In the stratified case database 13, a plurality of cases are classified by combinations of medical conditions and treatments, for example, for each disease classified by cause, disease state, and the like. For example, in FIG. 5, cases corresponding to disease A-classification a1-classification b1 are pathological conditions (pathology a, pathological condition b, pathological condition c,...) And treatment (treatment 1-treatment item 1, treatment 1-treatment item 2, ...)) and combination.

  “Ga11”, “Gb11”, and the like in FIG. 5 are group names of classification. For example, Ga11 corresponds to case data relating to a patient who has been treated 1 for the medical condition a among the patients suffering from the disease A-classification a1-classification b1.

  For example, in the case of diabetes, as shown in FIG. 6, for example, “type 1 diabetes”, “type 2 diabetes” and the like fall under the classification, and for example, “low insulin secretion ability”, “high insulin secretion ability”, “post-meal” “Hyperglycemia” and the like fall under the category of disease state. For example, “HbA1c: 7.2”, “complication: retinopathy” and the like correspond to medical conditions, and “diet therapy”, “exercise therapy”, “oral drug therapy” and the like correspond to treatments, for example.

  For example, with regard to diet therapy, the degree of protection of an appropriate amount of energy instructed by a doctor was evaluated in three stages: “almost implemented”, “performed to some extent”, and “almost not implemented”. In this case, “almost implemented”, “implemented to some extent”, and “almost not implemented” correspond to the implementation items in FIG. That is, “diet therapy” — “almost implemented” is an example of “treatment 1” — “execution item 1” in FIG. “Unknown” in FIG. 5 represents a case where it is unclear how much the patient has performed the contents instructed by the doctor (for example, there is no record and the patient's memory is ambiguous).

  Next, how the case data is collected and classified will be described with reference to FIGS.

  In FIG. 7, treatment methods “t11-p”, “t21-p”, and “t31-p” are planned at a certain time point (yyyy / mm / dd) for patients suffering from disease A-classification a1-classification b1. (Here, “-p” indicates a plan).

  At the time of the next examination (YYYY / MM / DD), the change amount (here, mmm-nnn) for the disease state x1 is the treatment result (here, “t11-a”, “t21-a” and “t21-a”). t31-a ") and collected as case data (here," -a "indicates that it is a record).

  Specifically, “mmm-nnn” is added as case data to the group of disease A-classification a1-classification b1-pathology x1-treatment method t11 and treatment result t11-a. Similarly, “mmm-nnn” is added as case data to the group of disease A-classification a1-classification b1-pathology x1-treatment method t21 and treatment result t21-a. Similarly, “mmm-nnn” is added as case data to the group of disease A-classification a1-classification b1-pathology x1-treatment method t31 and treatment result t31-a.

  Suppose that new treatments “t12-p”, “t22-p”, and “t32-p” are planned on the same day (YYYY / MM / DD). Then, at the next examination (Yyyy / Mm / Dd), the amount of change (here, ppp-mmm) for the disease state x1 is the result of treatment (here, “t11-a” → “t12-a”). , “T21-a” → “t22-a” and “t31-a” → “t32-a”), and collected as case data.

  The stratified case database 13 is updated as needed by repeatedly performing the above-described processing. Note that the amount of change is not limited to the difference, and may be represented by a variation rate (for example, “(mmm−nnn) / nnn”).

  More specifically, as shown in FIG. 8, for patients with type 2 diabetes and postprandial hyperglycemia (patients different from those shown in FIG. 2), on January 1, 2000, diet therapy and exercise therapy And oral drug therapy (drug name: glucobai) is planned. At the time of the examination on March 1, 2000, the value of HbA1c decreased by 0.4 (7.5 → 7.1), diet was “performed to some extent”, and exercise therapy was “almost never performed”. Suppose that oral drug therapy has a track record of “almost taking”.

  In this case, “difference-0.4” is “None (planned results)” of Gx1t11 (type 2 diabetes / postprandial hyperglycemia—HbA1c—diet corresponding to diet) — → “to some extent” (in FIG. 5) Collected as case data related to "execution item". The ratio means the ratio of the case data “difference−0.4” out of all the case data related to “none” → “implemented to some extent” of Gx1t11.

  Similarly, “difference−0.4” relates to “None (results at the planning stage)” → “Mostly not implemented” of Gx1t21 (type 2 diabetes / postprandial hyperglycemia—HbA1c—classification corresponding to exercise therapy) Collected as case data. Similarly, "difference -0.4" is a case of Gx1t31 (type 2 diabetes / postprandial hyperglycemia-HbA1c-classification corresponding to oral drug therapy) "none (result at the planning stage)" → "mostly taken" Collected as data.

(Prediction process)
Next, description is added about a prediction process.

  For example, for patients with type 2 diabetes and postprandial hyperglycemia (patients different from those shown in FIG. 2), the “treatment / risk prediction” screen shown in FIG. ”And“ Diet therapy: Mostly implemented (future) ”and then the“ Predict execution ”button is pressed.

  In this case, the management server 10 determines, from the stratified disease database 13, for example, the difference with the highest ratio among case data corresponding to “type 2 diabetes / postprandial hyperglycemia—HbA1c—diet therapy—some implementation → almost implementation”. The value obtained by adding the difference (here, -0.4) extracted to the current HbA1c value ("7.5" in FIG. 4) is displayed on the "treatment / risk prediction" screen. To do. The “ratio” in this case means the “ratio” shown in the lower part of FIG.

  Similarly, from the stratified disease database 13, the management server 10, for example, has the highest percentage of case data corresponding to “type 2 diabetes / postprandial hyperglycemia−fasting blood glucose level−dietary therapy−some implementation → almost implementation”. The high difference is extracted, and the value obtained by adding the extracted difference (here, “−10”) to the current fasting blood glucose level (“140” in FIG. 4) is displayed on the “treatment / risk prediction” screen. To display.

  Similarly, from the stratified disease database 13, the management server 10, for example, has the largest proportion of case data corresponding to “type 2 diabetes / postprandial hyperglycemia−postprandial 2 h blood glucose level−diet therapy—some implementation → almost implemented”. A high difference is extracted, and the value obtained by adding the extracted difference (here, “−60”) to the current post-meal 2 h blood glucose level (“280” in FIG. 4) is displayed on the “treatment / risk prediction” screen. To display.

  Regarding the complication risk, the management server 10 determines the treatment period and onset from case data corresponding to, for example, “type 2 diabetes / postprandial hyperglycemia—complication / retinopathy—diet therapy—some implementation → almost implementation”. What is necessary is just to extract the information regarding the presence or absence of and to display on the "treatment / risk prediction" screen. If medical costs are included as an element of case data, prediction of medical costs can be realized relatively easily.

  The “management server 10” and the “terminal device 20” according to the embodiment are examples of the “other identification unit” and the “input unit” according to the present invention, respectively. The “management server 10” and “terminal device 20” according to the embodiment are examples of the “output unit” according to the present invention. The “patient profile 11” and the “patient medical care database 12” according to the embodiment are examples of the “patient database” according to the present invention.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification, and an information display device with such a change And methods and computer programs are also included in the technical scope of the present invention.
