Development of a FHIR-based Korean IPS Data Pipeline and User-Centered UI Design

Area of Science:

• Health Informatics
• Digital Health Standards
• Healthcare Interoperability

Background:

• The International Patient Summary (IPS) is a global standard for essential health information exchange.
• Korea utilizes Fast Healthcare Interoperability Resources (FHIR) via the "My Health Record" application and KR Core profiles.
• A standardized method for converting Korean FHIR data to IPS format is currently lacking.

Purpose of the Study:

• To evaluate the feasibility of implementing an IPS-compliant patient summary in Korea.
• To assess the compatibility of existing Korean FHIR resources with IPS standards.
• To identify gaps and requirements for IPS implementation in the Korean healthcare system.

Main Methods:

• Literature review on IPS standards and interoperability.
• Gap analysis comparing IPS requirements with KR Core FHIR profiles.
• Transformation of real-world FHIR data to IPS format using ChatGPT-4o.
• Validation using HAPI FHIR and SMART FRED tools.
• User requirement gathering via personas and expert consultations.
• Development of a prototype user interface using Figma.

Main Results:

• Six of seven IPS components mapped to ten KR Core profiles; "Device" and "MedicationStatement" lacked direct mapping.
• Approximately 86% of required IPS data elements were represented by existing Korean FHIR resources.
• User requirements emphasized the need for summary and timeline-based UI features.

Conclusions:

• The implementation of IPS in Korea is technically feasible using current FHIR-based resources.
• Gaps in terminology coverage and profile alignment need to be addressed for comprehensive IPS deployment.
• Future efforts should prioritize multi-site validation, automated mapping, and robust governance frameworks.
