Implementation of Medical Information Exchange System Based on EHR Standard

Area of Science:

• Health Informatics
• Medical Information Systems
• Data Interoperability

Background:

• Effective sharing of patient medical information is crucial for coordinated healthcare.
• Existing systems often struggle with exchanging diverse data types across different platforms.
• Ensuring patient data security during electronic exchange is a significant challenge.

Purpose of the Study:

• To develop an innovative Medical Information Exchange System (MIES) for seamless patient data sharing.
• To establish a secure and interoperable platform for exchanging various medical data types.
• To implement robust security measures for online medical information services.

Main Methods:

• Developed a MIES centered around a registry server for managing information exchange.
• Adopted standardized data transfer methods and terminologies from the Center for Interoperable Electronic Healthcare Record (CIEHR) of Korea.
• Implemented comprehensive security systems including communication encryption, server, database, content, and network security, adhering to CIEHR guidelines.

Main Results:

• The registry server successfully managed information exchange and registration of Clinical Document Architecture (CDA) documents.
• A dedicated CDA Transfer Server facilitated the retrieval and transmission of appropriate CDA documents.
• The CDA viewer enabled visualization of CDA documents by connecting with information systems of associated hospitals.

Conclusions:

• The MIES successfully enabled the exchange of CDA documents between disparate systems using ebXML, following defined document standards.
• The system's independent central registry server model ensures the essential security of patient medical information.
• The developed MIES provides a viable solution for secure and interoperable medical information exchange.
