Summary
This study details information models for a federated health record server, refined by a decade of European experience and deployed in a clinical setting. These models support comprehensive multi-professional electronic health records.
Area of Science:
- Health Informatics
- Medical Information Systems
Background:
- Over a decade of European experience in electronic health records (EHRs) has been accumulated.
- Collaboration with diverse healthcare and informatics organizations across Europe has informed this work.
- EU Health Telematics projects (GEHR, Synapses, EHCR-SupA, SynEx, Medicate) have contributed to EHR development.
Purpose of the Study:
- To describe information models for implementing a federated health record server.
- To detail the deployment of this server in a live clinical setting.
- To present refinements to information models based on practical implementation experience.
Main Methods:
- Development of information models for federated health record architecture.
- Implementation of a federated health record server at University College London (UCL).
- Deployment and operational use of the server in a clinical environment (Whittington Hospital).
Main Results:
- Successful implementation and deployment of a federated health record server.
- Information models have been refined based on real-world clinical use.
- Architecture models have influenced European standardization efforts (e.g., CEN TC/251 ENV 13606).
Conclusions:
- The described information models are robust and validated through clinical deployment.
- Federated health record systems are feasible and beneficial in multi-professional settings.
- Ongoing refinement of information models is crucial for advancing EHR systems.
