Abstract:
The secondary use of clinical data is crucial for advancing medical research, yet it remains challenged by data fragmentation, privacy concerns, and limited availability. This paper presents a data-trustee infrastructure designed to enable secure, privacy-preserving access to retrospective medical data stored in Hospital Information Systems (HIS). The infrastructure leverages Fast Healthcare Interoperability Resources (FHIR) standards to ensure interoperability and employs a modular pipeline. The pipeline extracts, preprocesses, encrypts, and annotates the data in the hospital and then stores data in a trustee repository. A central component—the Study Specification Board—facilitates ethical and formalized study planning, while a privacy-preserving, two-phase search mechanism allows researchers to retrieve relevant data without exposing sensitive information. A demonstrator system has been implemented and successfully integrated with an HIS, confirming the feasibility and practical applicability of the approach. This work represents a significant step toward operationalizing secure clinical data sharing aligned with EU-GDPR and the goals of the European Health Data Space.
