Standardized EHR interoperability - preliminary results of a German pilot project using the archetype methodology

Area of Science:

• Health Informatics
• Medical Interoperability
• Digital Health

Background:

• Healthcare professionals and patients face challenges due to language barriers in electronic health record (EHR) systems.
• International mobility necessitates continuous patient care, requiring physicians to access and understand foreign patient records.

Purpose of the Study:

• To develop a solution addressing linguistic and interoperability issues in EHR systems.
• To facilitate seamless data exchange between heterogeneous EHR systems.

Main Methods:

• Utilizing ASTM CCR-derived medical concepts to define an ISO 13606-based interface model.
• Implementing a server for data exchange management, supporting web services and web forms.
• Performing data transformation from legacy schemes to a common structure.

Main Results:

• A standardized interface model based on ISO 13606 facilitates EHR system interoperability.
• A central server manages data exchange, enabling automatic and manual data access.
• The solution includes rich visualization features like language switching for enhanced usability.

Conclusions:

• The developed solution effectively addresses multilingualism and interoperability challenges in EHR systems.
• Standardized data models and a central server architecture improve global healthcare data accessibility and continuity of care.
