Summary
We developed the Korean (K)-CDA IG for standardized health information exchange (HIE). This national guide facilitates local data requirements, improving patient care continuity and EHR interoperability.
Area of Science:
- Health Informatics
- Medical Informatics
- Health Information Exchange
Background:
- Health Information Exchange (HIE) is crucial for patient care continuity.
- Standardized data is essential for HIE effectiveness.
- Existing Clinical Document Architecture (CDA) Implementation Guides (IGs) lack development process details and local adaptability.
Purpose of the Study:
- To develop a national CDA IG tailored to local requirements in Korea.
- To detail the development process and technical methods for the Korean (K)-CDA IG.
- To enhance health information exchange and EHR interoperability within Korea.
Main Methods:
- A three-stage development process: analysis, development, and evaluation.
- Investigated the Korean health information environment and EHR systems.
- Conducted gap analysis with existing CDA IGs and utilized a templated CDA approach.
- Consulted a technical advisory group for validation.
Main Results:
- Developed 35 CDA templates.
- Improved 28 value sets, with 13 being Korea-specific.
- Established rules for the Object Identifier (OID) structure.
Conclusions:
- Successfully developed the K-CDA IG meeting local requirements.
- The K-CDA IG can serve as interoperability criteria for national EHR certification.
- Provided recommendations for other countries developing HIE programs.

Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

Source-oriented records, or SOR, are medical record-keeping organized by the data source. The SOR system was first developed in the mid-1900s to organize the growing patient data in hospitals and other healthcare facilities.
In an SOR, each discipline involved in patient care maintains a separate medical record section. This record-keeping method enables easy tracking of patient progress and ensures healthcare staff have access to up-to-date information.
Key Attributes include the following:
