The European Commission's Directorate-General for Health and Food Safety has published frequently asked questions guidance on the European Health Data Space (EHDS), setting out the objectives, scope, and implementation of Regulation (EU) 2025/327 for relevant stakeholders. It establishes a framework for the secure use and sharing of electronic health data across the EU, structured around primary use for healthcare delivery, secondary use for research and policy purposes, and requirements for interoperable electronic health record systems, while granting patients enhanced rights to access, control, and share their data. The guidance explains obligations on Member States to establish digital health authorities and infrastructure, on manufacturers to ensure compliance and interoperability of systems, and on health data holders to make specified datasets available under regulated conditions overseen by health data access bodies. It also outlines a phased implementation from 2029 and 2031, supported by implementing acts and governance structures, and clarifies the relationship with existing EU legislation, including the GDPR, to enable secure, interoperable, and efficient use of health data across the Union. The 26 March 2026 update expands the guidance by adding new questions, including clarification for manufacturers of medical devices, in-vitro diagnostic devices, and high-risk AI systems interoperable with electronic health record systems (Q.24), addressing how EHDS requirements apply alongside existing regulatory frameworks.
