Description

  The present invention relates to a medical information search system, a medical information search gateway device, a medical information search method, and a program. For example, the present invention relates to a technology for providing a user with information necessary for medical work without being conscious of restrictions on storage of medical data. .

  In recent years, in order to exchange and share medical data between various medical institutions, a system that standardizes and stores medical data has been proposed. Examples of such so-called standardized storage include SS-MIX2 standardized storage and SS-MIX2 extended storage (Non-Patent Document 1). Here, the standardized storage stores medical data according to the standardized folder structure and data file structure. The extended storage stores a predetermined type of file.

  In addition, as an example of a system using such a standardized storage, in Patent Document 1, patient data compliant with a standard such as HL7 is stored in a repository, and a patient is received from the repository in response to a request from an external system. A computer system having a function of searching for data and outputting a search result to an external system is described.

  However, conventionally, in order to obtain desired medical data from the standardized storage, after understanding the standardized data structure, the record or file containing the data item to be obtained is specified, and the record or file is It was necessary to write a program that obtains the value of a desired data item.

  For example, in a certain standardized storage, as shown in FIG. 1, it is assumed that a data file in which patient medical data is recorded is stored according to a folder structure as shown in FIG. Here, it is assumed that the user wants to acquire medical data on a specific date for a specific patient. In this case, the user first searches for a folder corresponding to the patient ID of the specific patient, and then searches the folder corresponding to the specific medical date to obtain desired medical data from the data file. Need to create a program. As described above, in the conventional standardized storage, there is a problem that complicated prerequisite knowledge and complicated labor are required to acquire medical data required by the user.

  In the medical field, for example, the user can obtain various data related to a certain prescription (such as prescription date, drug name, dosage amount, and administration route) and various data related to a plurality of examination orders performed on the same medical treatment day. , I want to handle it as a piece of information. This is because these data have the property of forming meaning by being combined. However, in the conventional standardized storage, since these data are managed as separate data items, the user has to specify and acquire these data individually. That is, there is a problem that a method for easily acquiring a plurality of data is not provided corresponding to a use case from the user's viewpoint.

  Furthermore, in clinical research, even if the measurement method, reagent, and test result format (quantitative value or qualitative value) used in the test are different, the same test is used as long as the purpose of the test is the same. May be treated as However, in the conventional standardized storage, if the measurement method, the reagent, the format of the test result, and the like are different, the test item code used is also different, so that it is treated as a completely different test. Therefore, the user may need to specify a plurality of different inspection codes in order to acquire data of a plurality of inspections that are regarded as the same type from the user's viewpoint. In this case, there is also a problem that the inspection data cannot be acquired without omission if there is an omission in the specification of the inspection code.

  Also, depending on the medical institution, a local code unique to a facility may be assigned to a certain data item in addition to a standard code. In such a case, there is a problem that it is necessary to specify which code is used as a search condition when searching for data. Further, when medical data is stored not only in the standardized storage but also in the extended storage, there is a problem that the user needs to further know the constraint conditions of the extended storage.

  The present invention has been made to solve such problems, and medical information capable of providing a user with information necessary for medical work without being aware of the constraints related to storage of medical data. It is an object to provide a search system, a medical information search gateway device, a medical information search method, and a program.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. First, the configuration of the medical information search system 100 according to the embodiment of the present invention will be described with reference to FIG.

  The medical information search system 100 is an information processing system including a medical information search gateway device 110 and a medical information search terminal device 130. The medical information search gateway device 110 and the medical information search terminal device 130 are connected to be communicable with each other.

  The medical information search gateway device 110 is an information processing device including a storage 111, an input unit 112, a search unit 113, and an output unit 114. Among these, the storage 111 is a storage for storing medical data according to a predetermined restriction condition. Typically, the storage 111 is SS-MIX2 standardized storage and extended storage. SS-MIX2 standardized storage has been standardized according to the Health and Welfare Information System Industry Association (JAHIS) standard according to Health Level Seven Version 2.5 (ISO: 27931) established by Health Level Seven (registered trademark) INTERNATIONAL Medical data (JAHIS standard) is stored. In the standardized storage, medical data is stored according to a predetermined folder structure and data file structure. The extended storage stores examinations and interpretation rates for radiation, endoscopes, etc., and the image information that accompanies them, as well as data files that have been created in a uniform format within a medical facility, although the standard has not yet been established. Is done. In the extended storage, the types of files that can be stored are defined in advance. For example, in addition to folders, the extended storage can store structured text having a predetermined extension, office documents, plain text, vector graphics, raster images, audio, moving images, medical waveforms, archives, and the like.

  FIG. 1 shows an example of a folder configuration in the SS-MIX standardized storage and extended storage. Here, a folder is created for each patient, treatment date, and data type, and a data file in which data items and values are recorded is stored in the data type folder. FIG. 2A shows an example of a data file in the SS-MIX standardized storage. In this data file, the inspection result for one inspection order is recorded as text data described according to the JAHIS standard.

  The medical information search terminal device 130 is an information processing device that transmits a search request for medical data to the medical information search gateway device 110. The medical information search terminal device 130 creates a search request according to the search condition input by the user. Here, the user does not need to know the data structure of the medical data stored in the storage 111 of the medical information search gateway device 110 in advance, and can input the search conditions according to what the user wants to implement at the medical site. . In addition, the medical information search terminal device 130 converts the search condition into a format according to a predetermined data exchange format and creates a search request. For example, JSON (Java Script Object Notation, Java Script is a registered trademark) is easy for users to understand the description, and is easy to generate for machines, so it is suitable as a data exchange format.

  The input unit 112 of the medical information search gateway device 110 receives a search request from the medical information search terminal device 130. The search unit 113 extracts a search condition from the search request, and acquires medical data corresponding to the search condition from the storage 111. Here, the search unit 113 generates and issues a search command according to the data structure of the storage 111 based on the extracted search condition. The storage 111 returns medical data corresponding to the search command to the search unit 113. In other words, the medical information search gateway device 110 bridges between the medical information search terminal device used by the user who wants to create search conditions according to the use case in the medical field and the storage 111 storing the medical data according to predetermined constraints. Act as a gateway to do.

  The output unit 114 converts the medical data acquired from the storage 111 by the search unit 113 into a format according to a predetermined data exchange format, and transmits the result to the medical information search terminal device 130 as a search result. For example, the output unit 114 converts medical data described in the JAHIS standard returned by the medical information search gateway device 110 into a JSON format that is highly readable by the user, and outputs the search result to the medical information search terminal device 130. Can be sent. In other words, the medical information search gateway device 110 also functions as a gateway that converts medical data stored in the storage 111 according to predetermined constraints into search results in a format that is easy for the user to handle. 2B and 2C show an example of the inspection result output in the JSON format. In this file, the inspection result described in the JAHIS standard in FIG. 2A is converted into the JSON format and recorded as text data.

  Next, modes of operation of the medical information search system 100 according to the present embodiment will be disclosed as Examples 1 to 7.

<Example 1>
In clinical practice and clinical research, it is extremely important to identify when and under what circumstances a test result is a test performed. Therefore, in the first embodiment, a search method for designating how long or the number of times of data should be acquired with a certain medical treatment date as a baseline will be described. As a search condition, the user designates a reference date (for example, an operation date, a hospitalization date, or the like) serving as a search baseline, and the number of retroactive days or the number of retroactive times from the reference date (past / future) reference date. Thereby, the user can acquire a time-series inspection result as a search result.

  Example 1 will be described using specific use cases. Now, it is assumed that the storage 111 of the medical information search gateway device 110 holds past test results and prescription contents concerning a patient who has undergone liver cancer resection surgery. Then, it is assumed that the doctor desires to obtain three types of test values AST, ALT, and ChE indicating the liver function state before the operation of a patient who has undergone a liver cancer resection operation for clinical research.

  Here, since these test values may fluctuate greatly every day, it is desired to acquire the latest test values that are acquired as close as possible to the surgery date. In addition, since the above-described three types of inspection values are related and fluctuate, it is desired to obtain three types of inspection values on the same day as much as possible. However, if it is not possible to find three types of test values on the same day unless it goes back more than two weeks from the date of surgery, it is unavoidable, and we would like to acquire two types of test values performed on the same day immediately after the date of surgery. In addition, since many of the test values are affected by the prescription drugs being taken, we would like to obtain all the prescription contents for the patient within one month from the date of the test.

  For example, as shown in Example 1 of FIG. 3, the operation date is March 30, and AST and ALT test values exist on March 28, but ChE has not been tested. March 26 If there are three types of test values, the three test values on March 26 will be acquired instead of the test value on March 28 that is the most recent operation day. However, as shown in Example 2, if it is not possible to find three types of test values on the same day even if it goes back more than two weeks from the date of surgery, only the two types of test values of AST and ALT exist on March 28 I want to get the data.

  In order to deal with such a case, the medical information search system 100 acquires the results of tests performed within the past two weeks using the operation date, that is, March 30 as the reference date, and the acquired test. What is necessary is just to arrange a value in time series and present it to a doctor. That is, when the user designates a time range as a search condition, the medical information search system 100 may comprehensively acquire examination data included in the time range and present it to the user. Then, the doctor can easily select an appropriate set of test results. In addition, the medical information search system 100 may present the contents of the prescription performed within the past six weeks with the operation date, that is, March 30 as the reference date. That way, doctors have enough data to assess the effect of prescription drugs on test values.

  4A is an example of search conditions that the user should input to the medical information search terminal device 130 in the above case. First, the patient ID (12345567890) designates which patient wants to obtain data. In addition, as an inspection result, an inspection item code (3B035000002327201, 3B045000002327201, 3B110000002327101) is specified as to which inspection item to obtain the inspection value. Furthermore, what element of the inspection item is desired to be acquired is designated by a code (OBX-5, OBX-6, OBX-7). The elements included in the inspection item include various types of information such as an inspection value and an inspection method, but here, the inspection value is acquired. Then, the time range of the inspection value to be acquired is designated by the reference date (March 30, 2016) and the retroactive date (the past 14 days). Moreover, the prescription order prescribed | regulated to the said patient, ie, the time range at the time of acquiring pharmaceutical information, is designated by the reference date (March 30, 2016) and the retroactive date (past 6 weeks).

  The medical information search terminal device 130 preferably provides a user interface for the user to input these search conditions. The user interface may, for example, select a code or date that can be specified as a search condition from preset input candidates, or display only a necessary interface according to a combination rule of search conditions defined in advance. It is possible to make it possible for the user to easily input the search condition by controlling.

  The lower diagram in FIG. 4A is an example of a search request created by the medical information search terminal device 130 in accordance with the search condition input by the user. In this example, the medical information search terminal device 130 creates a JSON-format text message including a search condition, and transmits this to the medical information search gateway device 110 as a search request.

  The input unit 112 of the medical information search gateway device 110 receives a search request in JSON format including a search condition from the medical information search terminal device 130. Then, the search unit 113 converts this search request into a message for searching for SS-MIX standardized storage or extended storage, that is, a search command. Here, the syntax of the search command is known. Therefore, the search unit 113 can hold in advance a correspondence relationship (mapping) between the search condition included in the search request and the search condition to be included in the search command. The search unit 113 can convert a search request into a search command by referring to this correspondence.

  The search unit 113 acquires medical data from the storage 111 using the created search command. Here, the format of the acquired medical data is, for example, the JAHIS standard.

  Then, the output unit 114 converts the medical data into a data format that can be easily read by the user. 4B, 4C, 4D, and 4E show examples of medical data converted into JSON format text data. The first block (lab) is further divided into a plurality of small blocks for each inspection date, and each small block includes an inspection item and its inspection value existing on that day. The next block is further divided into a plurality of small blocks for each prescription date, and each small block includes a prescription order for the day. The output unit 114 transmits the created converted medical data to the medical information search terminal device 130 as a search result.

  The medical information search terminal device 130 receives the search result from the medical information search gateway device 110. Typically, the medical information search terminal device 130 can output the received search result as it is. Alternatively, the medical information search terminal device 130 may generate a display screen on which information is organized so that the user can more easily understand the content based on the search result, and present it.

<Example 2>
In Example 2, the contents of the prescription order that can be acquired by the medical information search system 100 according to Example 1 will be described in more detail.

  FIG. 5A is an example of a prescription order that the storage 111 of the medical information search gateway device 110 holds in accordance with the JAHIS standard. As described above, in the standardized medical data, the prescription date, the drug name, the dosage, the usage, the administration route, and the like are described by codes and formats that are remarkably low in legibility. Therefore, it is difficult for the user to directly create a search condition for extracting necessary data from the prescription order message. Moreover, even if the search result extracted from this prescription order message is directly returned to the user, it is difficult for the user to interpret it.

  5B and 5C are examples of search requests and search results transmitted and received in the medical information search system 100. FIG. Here, the search result is divided into a plurality of blocks for each prescription date. The block on the prescription date is further divided into a plurality of small blocks for each drug name, and each small block describes the dosage, usage, administration route, etc. of the drug in an organized manner. Therefore, even if the search result is presented as it is, the user can grasp the prescription order (prescription date, drug name, dose, dosage form, usage, administration route, etc.) remarkably easily compared to the conventional case. . In addition, since the search result can be easily processed, it is also easier than before that the medical information search terminal device 130 processes the search result and presents it to the user.

<Example 3>
In the third embodiment, the contents of test results that can be acquired by the medical information search system 100 according to the first embodiment will be described in more detail using two use cases.

  The first use case is that a certain number of test results are acquired for a patient based on the test execution date. FIG. 6A is an example of a test result stored in the storage 111 of the medical information search gateway device 110 in accordance with the JAHIS standard. As described above, in the medical data stored in accordance with the predetermined constraint conditions, various pieces of information related to the test result are described in codes and formats with extremely low legibility. Therefore, it is difficult for the user to directly create a search condition for extracting necessary data from the inspection result message. Moreover, even if the search result extracted from this test result message is directly returned to the user, it is difficult for the user to interpret it.

  FIG. 6B is an example of search requests and search results transmitted and received in the medical information search system 100. The search request is created by the medical information search terminal device 130 based on the search condition input by the user. The search condition includes a condition for designating a search range such as “for the past 10 times from December 10, 2014”. The test result output by the medical information search gateway device 110 after converting the JAHIS standard to the JSON format is divided into a plurality of blocks for each test date, and the test results for the day are arranged in each block. Has been. If a plurality of inspection orders are executed on the same day, the inspection results are described in a plurality of small blocks. That is, according to the medical information search system 100, test results that satisfy a certain search condition are acquired in a batch in a form that is ordered for each test execution date and for each of a plurality of test orders performed on the same medical treatment date. It is possible. Therefore, even if the user presents the search result as it is, the user can grasp the inspection result remarkably easily as compared with the conventional case. In addition, since the search result can be easily processed, it is also easier than before that the medical information search terminal device 130 processes the search result and presents it to the user.

  The second use case is an examination result relating to a certain patient, and a plurality of examination results belonging to the same order are desired to be acquired together. In addition, since the patient was after the meal on the day when the patient was instructed to test, biochemical tests and urine tests other than fasting blood glucose test were performed. Only the fasting blood glucose test was performed the next day.

  7A and 7B are examples of test results of the above-described series of tests stored in the storage 111 of the medical information search gateway device 110 according to the JAHIS standard. In this example, even if examinations are based on the same order, examinations performed on different days are stored in different data files in different folders.

  FIG. 7C is an example of search requests and search results transmitted and received in the present embodiment. The search request is created by the medical information search terminal device 130 based on the search condition input by the user. The search conditions include, for example, a search condition such as designation of a patient ID and “the past 10 times from December 10, 2014”. In this case, the search unit 113 of the medical information search gateway device 110 creates a search command for searching across a plurality of data files based on the search request. Further, the output unit 114 converts the JAHIS standard medical data extracted from the storage 111 into the JSON format, and creates a search result. In the search result, a plurality of test results for the same patient are combined into one message. The search results are divided into a plurality of blocks for each inspection date, and the inspection results for the day are arranged and described in each block. If a plurality of inspection orders are executed on the same day, the inspection results are described in a plurality of small blocks. That is, according to the medical information search system 100, test results that satisfy a certain search condition are acquired in a batch in a form that is ordered for each test execution date and for each of a plurality of test orders performed on the same medical treatment date. It is possible. Therefore, according to this search result, the user can collectively check a plurality of inspection results belonging to the same order.

<Example 4>
In clinical examinations, even for the same examination item, the examination item code to be used differs depending on the measurement method, reagent, result format (quantitative value or qualitative value), and the like. However, in clinical studies, there are many cases where they want to treat them as the same test item. Therefore, the medical information search system 100 according to the fourth embodiment can absorb differences in measurement methods, reagents, and result formats (quantitative values or qualitative values) in clinical tests, and acquire test results as the same test item. A possible search method will be described. On the other hand, when it is necessary to strictly distinguish measurement methods and the like, the medical information search system 100 can acquire a desired test result by performing a search specifying the measurement method.

  Example 4 will be described using a specific use case. I want to search for the results of the past 3 years of HbA1c from a patient at Hospital A. However, since the measurement method of HbA1c has been changed one year ago in Hospital A, the SS-MIX2 storage 111 of the medical information search gateway device 110 stores the test results of HbA1c by a plurality of measurement methods. That is, the test results by immunological methods (latex aggregation turbidimetry, etc.) used before the change of measurement method and the test results by HPLC (unstable fraction removal HPLC method) used after change of the measurement method is there.

  At this time, using the interface provided by the medical information search terminal device 130, the user designates the patient ID, the reference date, the retroactive period as a search condition, and the measurement method, the result format, and the like as examination items. In this example, the user specifies two different measurement methods: an immunological method (such as latex agglutination turbidimetry) and HPLC (unstable fraction removal HPLC method). The medical information search terminal device 130 generates a search request based on the search condition input by the user.

  8B and 8C are examples of search requests and search results transmitted and received in this embodiment. In the search request, the inspection item to be acquired is specified by a 17-digit code. In addition, in the 17-digit code, in the portion corresponding to the 13th to 15th digits, two types of numerical values “062” and “204” are alternatively described using regular expressions.

  Here, the above-mentioned 17-digit code is the standard search item code JLAC10 used in SS-MIX2 (HL7). As shown in FIG. 8A, the portion corresponding to the 13th to 15th digits of JLAC10 is a code indicating the measurement method. For example, if this is “062”, “immunological method (latex aggregation turbidimetry, etc.)” is designated as the examination method, and “204” is designated as the examination method, “HPLC (unstable fraction removal)” HPLC method) ”. That is, the above search request is for requesting to obtain a test result whose test method is “immunological method (latex aggregation turbidimetry etc.)” or “HPLC (unstable fraction removal HPLC method)”. It has become.

  In the search results, a plurality of test results whose test methods are “immunological method (latex aggregation turbidimetric method, etc.)” or “HPLC (unstable fraction removal HPLC method)” are collected in one message. . That is, the search results are divided into a plurality of blocks, and each block has an “immunological method (latex aggregation turbidimetric method, etc.)” or “HPLC (unstable fraction removal HPLC method)”. The test results which are either are arranged and described. If the same patient is tested with "immunological methods (latex aggregation turbidimetry, etc.)" and "HPLC (unstable fraction removal HPLC method)" The inspection results are listed. That is, according to the medical information search system 100, it is possible to collectively obtain the inspection results of the inspection items that can be regarded as the same although the inspection methods are different.

<Example 5>
In SS-MIX2, a standard code and a local code can be written together as a method for specifying an inspection item code (see FIG. 9B). That is, for the same inspection item, at least one of the standard code and the facility-specific local code can be designated as the inspection item code. Some inspection items are not assigned standard codes but only local codes are set. Therefore, if the user tries to directly search the SS-MIX 2 storage 111 as in the prior art, it is necessary to be aware of which code is used when specifying the search condition. However, according to the present embodiment, the user can acquire the inspection result without being aware of the difference in code.

  FIG. 9A is an example of a search request transmitted / received in the present embodiment. As shown in FIG. 9B, in the storage 111 of the medical information search gateway device 110, one of the inspection item codes of the standard code “3D046000002226101” and the local code “L1048” is assigned to the inspection of HbA1c. Shall. In this case, if the medical information search terminal device 130 is requested by the user to acquire the HbA1c test result, the medical information search terminal device 130 creates a search request specifying both the standard code and the local code.
