Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical information storing method,

The present invention relates to a medical information storing method, a system and a recording medium for performing the same, and more particularly, to a medical information storing method by linking documents and meta information between HL7 FHIR and IHE XDS.b, And a recording medium.

The medical information includes medical information and diagnosis information for the patients diagnosed at the hospital. Therefore, medical information sharing between medical institutions and medical devices plays an important role in improving the quality of medical care and improving the convenience of consumers.

In general, medical information sharing can be divided into cases of sharing information between systems in a hospital and sharing information between systems of a medical institution. First, when sharing medical information between systems in a hospital, various medical devices and independent systems such as a laboratory information system (LIS) share information with the hospital information system in the hospital.

These medical devices and independent systems provide various test results for the patients, so they must be integrated and operated with the hospital information system in order to provide high quality services. Accordingly, medical institutions are currently trying to improve the interoperability of medical information exchange by creating a medical record in the form of a CDA (Clinical Document Architecture) document, which is a standard of clinical documents belonging to the HL7 (Health Level 7) standard.

Recently, Cross Enterprise Document Sharing (XDS.b), an integrated profile designed to facilitate registration, distribution, and sharing of electronic medical records between medical institutions, was presented by IHE (Integrating the Healthcare Enterprise). The ebXML (Electronic Business Extensible Markup Language) message used to store documents in IHE XDS.b-based document registration repository is too complex and heavy to use in mobile environments.

In HL7 (Health Level 7), we developed a new standard called FHIR (Fast Healthcare Interoperability Resources). Metadata including representative information of documents and documents can also be created and managed based on this standard. have.

However, since the document registration repository based on IHE XDS.b is required to be used when exchanging document based medical information, a method of linking HL7 FHIR based document and meta information to IHE XDS.b is needed.

1 is a block diagram of a medical information storage system in accordance with an embodiment of the present invention.

Referring to FIG. 1, a medical information storage system 10 according to an embodiment of the present invention includes at least one HL7 FHIR server 100 and a document registration storage 300.

The HL7 FHIR server 100 and the document registration repository 300 may be connected to each other by a wireless communication, a wired communication, an internal network, or the like. Various applications are possible.

The HL7 FHIR server 100 and the document registration repository 300 may be configured to store the medical information stored in the medical record storing and management system 100. [ And software for management.

The HL7 FHIR server 100 and the document registration repository 300 may be separate terminals or some modules of the terminal. The HL7 FHIR server 100 and the document registration repository 300 may be mobile or fixed. The HL7 FHIR server 100 and the document registration repository 300 may be in the form of a server or an engine and may be a device, an apparatus, a terminal, a user equipment ), And so on.

HL7 FHIR stands for Health Level 7 Fast Healthcare Interoperability Resources and refers to the standard technology developed by HL7 for the purpose of enhancing the Health Information Exchange (HIE) paradigm, such as HL7 V2.x massage and the HL7 Clinical Document Architecture . The HL7 FHIR server 100 may refer to a device that performs data processing using FHIR standard technology or stores information as a result of the processing.

The document registration repository 300 is based on IHE XDS.b. IHE (Integrating the Healthcare Enterprise) is an organization that develops and provides standards-based profiles to ensure interoperability between medical information systems. Cross-Enterprise Document Sharing (XDS.b) It is an integrated profile designed to facilitate sharing. In addition, an ebXML (Electronic Business Extensible Markup Language) message is used as a standard for exchanging documents with the document registration repository 300 based on IHE XDS.b.

The present invention provides compatibility for storing the documents generated on the basis of the HL7 FHIR standard in the HL7 FHIR server 100 in accordance with the structure of the IHE XDS.b based document registration repository 300. [

The HL7 FHIR server 100 generates and stores the medical information entered by the user 20 into the HL7 FHIR standard based document and stores the HL7 FHIR standard based document in the IHE XDS.b based document registration storage 300 ebXML message is generated and transmitted. The HL7 FHIR server 100 may be at least one, and may include a plurality of HL7 FHIR servers 100 installed in each medical facility or one medical facility.

Referring to FIG. 2, the HL7 FHIR server 100 includes a storage unit 110, an extraction unit 130, a message generation unit 150, and a transmission unit 170. In addition, the HL7 FHIR server 100 may provide a user interface (UI) for providing convenience for the user 20 to store medical information.

The storage unit 110 stores the medical information inputted by the user 20 as a document based on the HL7 FHIR standard. The user 20 may be a medical staff such as a doctor, a nurse or the like, and the user 20 may designate the file name of the document at the time of storing the medical information. The storage unit 110 generates a document based on the HL7 FHIR standard and stores the medical information in a specific folder. The specific folder may be a binary folder defined in the HL7 FHIR standard.

For example, the stored document may be a CDA (Clinical Document Architecture) document, which is a standard of a clinical document, and may include a header and a body. Various information such as a CDA document can be recorded in a header, and various data such as medical care information can be recorded in a body. The information that a clinical document has in common is listed in the header, and information that differs depending on the characteristics of the clinical document can be displayed in the body.

Specifically, the header may include information on the document itself and information such as a document creator, a target person of the document, a custodian, and a legal authenticator. The body may contain medical information generated by actual medical practice. The body may include human readable textual elements and machine readable entry and section elements.

The body of a CDA document may contain a code indicating the degree of confidentiality of the document. Depending on the degree of confidentiality, the body of the CDA document may be classified into a normal access level, a restricted access level, and a very restricted access level .

An integrated header of a CDA document may include items such as recordTarget (patient), author (author), custodian (hospital), and the like. Here, the recordTarget item contains information about the patient and the caregiver. Specifically, patient identification mechanisms represent patient information including the patient's identity, patient characteristics, patient name, address, and phone number.

The author field shows information about the document creator who created the document. Specifically, it includes the time at which the document was created, the id of assignedAuthor, the name of the doctor who issued the prescription, and the like. The custodian item shows information about the organization where the document is created and managed. Specifically, it includes the address of the medical institution and the medical institution where the prescription is made.

The extraction unit 130 extracts document resource and meta information from the stored HL7 FHIR standard based document. Specifically, the extracting unit 130 extracts resources of a document stored in a specific folder among the stored documents based on the HL7 FHIR standard. The specific folder may be a binary folder of the HL7 FHIR server. The extraction unit 130 extracts the document reference information of the document based on the stored HL7 FHIR standard and extracts the meta information.

The message generating unit 150 generates a document registration and storing message including a resource and meta information of the HL7 FHIR standard based document extracted by the extracting unit 130. [

The document registration storage message uses an ebXML (Electronic Business Extensible Markup Language) message as a standard, for example, according to the ebXML v3.0 standard. That is, the resource and the meta information of the document based on the HL7 FHIR standard are included in the ebXML message and transmitted. For reference, FIG. 3 shows an example of an ebXML message to be registered while providing a CDA document.

The transmission unit 170 transmits the document registration storage message generated by the message generation unit 150 to the document registration storage 300. The document registration storage message includes resources and meta information of a document based on the HL7 FHIR standard.

The document registration storage 300 receives the document registration storage message and extracts the resource and the meta information of the document and stores the same. As described above, the document registration repository 300 is based on IHE XDS.b and uses an ebXML (Electronic Business Extensible Markup Language) message. ebXML uses the Registry / Repository abbreviation in the standard document because it basically uses the Registry and Repository concept as a standard for exchanging documents.

4, the document registration repository 300 includes a parser 310, a document repository 330, and a document register 350. [ Referring to FIG. 5, in another embodiment, the document registration storage 300 may further include a sharing unit 370.

The parser 310 parses the document registration storage message and extracts the resource and meta information of the document from the document registration storage message.

The document repository 330 stores resources of the document. In the ebXML standard, the repository can use file systems or dbs to store documents.

The document registry 350 stores meta information of the document. In the ebXML standard, the Registry stores information about documents, user information, institutional information, etc. and stores association information and audit information. In addition, the ebXML RIM standard defines the elements to be stored and managed in the registry, and the ebXML RS defines the messages needed to communicate with the registry.

The document registration storage 300 may further include the sharing unit 370. The sharing unit 370 provides the medical information requested by the user 40. [ The document registration repository 300 may provide a user interface (UI) for facilitating information retrieval and browsing of the user 40.

The user 40 may be the same as the user 20 of Fig. 1, or may be a different person. In addition, the users 40 may belong to the same medical institution, but may belong to other medical institutions. If the user 40 belongs to another medical institution, it is possible to share and utilize medical information among the medical staff.

The user 40 may make a search request through a user interface to search for a desired document, and the user input may be transmitted to the sharing unit 370 in the form of an ebXML meta information query. The document retrieval is performed using the meta information stored in the document repository 350, and the document repository 330 provides a document corresponding to the retrieved document.

Accordingly, interoperability can be enhanced by linking the documents based on the HL7 FHIR standard with the document registration repository based on the IHE XDS.b. In addition, since the exchange of documents between systems and institutions using different standard systems of medical information becomes convenient, the possibility of utilization of medical information can be increased.

6 is a flowchart illustrating a method of storing medical information according to an exemplary embodiment of the present invention.

The medical information storing method according to the present embodiment can be performed in substantially the same configuration as the medical information storing system 10 of FIG. Therefore, the same components as those of the system 10 of FIG. 1 are denoted by the same reference numerals, and repeated descriptions are omitted. Alternatively, the medical information storing method according to the present embodiment can be executed by software (application) for storing medical information.

Referring to FIG. 6, the medical information storing method stores a document based on the HL7 FHIR (Health Level 7 Fast Healthcare Interoperability Resources) standard (step S10). Medical information entered by users such as doctors and nurses is generated and stored in a document based on the HL7 FHIR standard. At this time, the document based on the HL7 FHIR standard may be stored in a specific folder, and the specific folder may be a binary folder defined by the HL7 FHIR standard.

When the document based on the HL7 FHIR standard is stored, the resource and meta information are extracted from the document (step S30). The resources of the document can be extracted from documents stored in a specific folder among the stored HL7 FHIR standards based documents. The specific folder may be a binary folder of the HL7 FHIR server. In addition, the meta information of the document can be extracted from the document reference of the document based on the stored HL7 FHIR standard.

When the resource and meta information of the document are extracted, a document registration and storing message (Provider And Register Document Set) including the resource and the meta information of the document is generated (step S50). The document registration storage message uses an ebXML (Electronic Business Extensible Markup Language) message as a standard, for example, according to the ebXML v3.0 standard.

When the document registration storage message is generated, it is transmitted to the document registration storage (step S70). That is, the resource and the meta information of the document based on the HL7 FHIR standard are included in the ebXML message and transmitted.

The document registration repository receives the document registration storage message and stores the document resource and the meta information in the document registration storage, respectively (step S90). The document registration repository is based on IHE XDS.b and uses an ebXML (Electronic Business Extensible Markup Language) message. ebXML uses document repositories and document registries as the standard for exchanging documents by default.

In the ebXML standard, the repository uses a file system or db as a place to store documents, and the Registry can store information about documents, user information, institutional information, etc. and store association information or audit information. In addition, the ebXML RIM standard defines the elements to be stored and managed in the registry, and the ebXML RS defines the messages needed to communicate with the registry.

The step of storing the resource of the document and the meta information in the document registration repository (step S90) includes parsing the document registration storage message to extract the resource of the document and the meta information, Stores it in a document repository of a document registration repository, and stores the meta information in a document registration registry of the document registration repository.

In addition, users can search and browse documents stored in the document registration repository. The user can make a search request through a user interface to retrieve a desired document, and the user input can be transmitted in the form of an ebXML meta information query. Document retrieval is performed using meta information stored in the document repository, and a document corresponding to the retrieved document is provided in the document repository.

Accordingly, interoperability can be enhanced by linking the documents based on the HL7 FHIR standard with the document registration repository based on the IHE XDS.b. In addition, since the exchange of documents between systems and institutions using different standard systems of medical information becomes convenient, the possibility of utilization of medical information can be increased.

Such a medical information storage method may be implemented in an application or may be implemented in the form of program instructions that can be executed through various computer components and recorded in a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, and the like, alone or in combination.

The program instructions recorded on the computer-readable recording medium may be ones that are specially designed and configured for the present invention and are known and available to those skilled in the art of computer software.

Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks and magnetic tape, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like.

Examples of program instructions include machine language code such as those generated by a compiler, as well as high-level language code that can be executed by a computer using an interpreter or the like. The hardware device may be configured to operate as one or more software modules for performing the processing according to the present invention, and vice versa.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. You will understand.

The medical information storage method according to the present invention can promote the universal use of the HL7 FHIR by storing the HL7 FHIR document in the IHE XDS.b-based registration repository. Accordingly, medical personnel can utilize various standards-based documents widely for medical treatment, and can be extended to the entire medical information / device convergence field. Furthermore, exchange and storage of information between heterogeneous standards is facilitated.
