In order to realize that the corresponding relation between the health information data elements and the health information standard can be obtained by analyzing the health information data elements with the minimum granularity, the reference data model can be trained, and then the matching of the relation can be completed by utilizing the reference data model.
The health information standard is a standard for data acquisition, storage and sharing in the health field, comprises document specifications, basic data sets and data element machine value domain codes of data exchange in each stage in the health management process, and restricts data representation in the data sharing process. The document specification is the specification of the electronic medical record/electronic health record shared document, and comprises the following steps: scope definitions for the specification, standard reference example tables, document content and structure specifications, examples, and the like. The specification of the document content and structure refers to data elements or other encoding specifications in other standards of health information. The hygiene data metadirectory includes a number of data values and their corresponding constraints that are required by the document specification. The hygiene data metadirectory includes a large number of data values and their corresponding constraints, such as data types, data formats, etc., that are required in the document specification. Meanwhile, the data values in the health data meta-directory sometimes refer to the value description of the specific data in the health data meta-value domain code or the value description of other encoding specifications. The health information standard knowledge linking model is shown in fig. 2, and defines three relations: "contain", "reference data model", "reference data value", reveal the internal association of these health information standards, form the associative link with data element as the center.
The health record/electronic medical record document specification can include a range of used files, terms, document contents, document structure specification, examples and the like. The health data element catalog comprises a data element A and a data element B, wherein each data element comprises basic elements such as a data element identifier, a data element name, a definition, a data type and the like, and the health data element value field code comprises a coding set.
Based on the model, the existing data is processed to form an interface supporting browsing and query. The main operations of data processing include: 1) analyzing the health information resource and extracting the data element; 2) entity encoding; 3) entity alignment and association.
The embodiment of the application aims at specific words and formats and extracts data in the health information standard through a strategy of combining OCR (optical Character recognition) recognition and manual verification.
The health information standard basic information identification comprises the following steps: standard number, standard name, release time and the like of the health information standard.
Identification of data elements, as shown in the health information standard knowledge link model diagram of fig. 2, the items in the data elements are stored as a whole when they occur. In addition, the data element allowable value sometimes refers to a value range code in other health information standards, the part of information needs to extract a standard name, a standard number and a value range code name and a code number where the data element value range code is located, and then a 'reference data value' relationship can be established by means of the part of information. At the same time, information of the hygiene information standard in which it is located is recorded, and then the "containing" relationship can be established by means of this part of the information.
Identification of data element value field codes, the common expression form of the data in the part is a form of a table, therefore, if a table head in the health information standard appears 'CV … code table', the data element value field codes are identified, and the structure, the content, the Chinese name of the table head (value field code name), the code of the table head (code number) and all the information of the health information standard of the table are identified and extracted.
Identification of other information, including the content of the part in the document specification of fig. 2, refers to the part data element information or other coding system information, and therefore, information of the hygiene information standard, the name of the related data element, the coding information and other coding system information of the part need to be stored. The relationship of the "reference data model" can then be established by virtue of this piece of information.
After data extraction, entity coding is mainly to code unique identifiers for each document (standard), data element and code table, so that warehousing management is facilitated.
Because there are two types of reference relations between the standards, including "reference data value" and "reference data model", according to the above data extraction, the information in the data matches the reference standard, data element, and code table name, and if the character string matches completely, the related association is established in the system. Complete matching requires consideration of ignoring space and letter case to improve recall. Fig. 3 includes examples of various types of health information standards, data elements, other coding specifications, and code tables, and the organization method described above is specifically described for the relevant information of "follow-up".
After the association is established, a browsing and querying system capable of supporting the data elements and the elements (names, identifications, definitions, types, values and the like) thereof is formed, and meanwhile, the reference relation of each standard and the data elements can be displayed.
As shown in fig. 3, the follow-up mode, the operation and operation code, and the gender code may be respectively in one-to-one correspondence with the related information in the hygiene data standard, i.e., which hygiene data standard the code mode is derived from may be determined by the code mode of the follow-up mode.
