Transferring Structured Medical Data from Hospital to Rehabilitation Facilities Using HL7 FHIR and openEHR

Area of Science:

• Health Informatics
• Medical Data Exchange
• Inter-institutional Communication

Background:

• Traditional paper-based health data transmission is often delayed and incomplete.
• Effective inter-institutional and inter-professional communication relies on prompt and complete health data transfer.
• Challenges exist in structured health data transfer from hospitals to rehabilitation facilities.

Purpose of the Study:

• To optimize inter-sectoral information provision for TAVI patients.
• To establish structured health data transfer from hospitals to rehabilitation facilities.
• To improve communication and care coordination in patient pathways.

Main Methods:

• Conducted requirement analysis via structured interviews with medical experts.
• Deployed web portal instances at two university medical centers for data access.
• Transformed medical and nursing data to FHIR and openEHR formats via data mapping.
• Utilized a Kubernetes system for secure data portal hosting.

Main Results:

• Successfully deployed web portals providing data access to rehabilitation facilities.
• Implemented structured data transfer using FHIR and openEHR standards.
• Included 142 patients in the ongoing clinical study.
• Demonstrated a unified concept with comparable data flows across different system architectures.

Conclusions:

• The CAEHR project successfully established a structured health data transfer system.
• The implemented system optimizes information provision between hospitals and rehabilitation facilities.
• The unified concept shows wide applicability despite varying institutional system architectures.
