HL7 Europe and IHE-Europe open ballot on two EHDS FHIR Implementation Guides

HL7 Europe and IHE-Europe opened coordinated ballots for two Fast Healthcare Interoperability Resources (FHIR) Implementation Guides built under their EURIDICE collaboration: the Imaging Study Report IG and the EU Health Data API IG. Both define electronic health record (EHR) functionalities meeting the interoperability requirements of the EHDS Regulation (EU) 2025/327, with comments and votes due by 30 April 2026. Both organisations are offering the specifications to the European Commission for reference in EHDS Implementing Acts, positioning them as the technical baseline for interoperability compliance when the regulation applies from March 2027. EHR vendors and national implementation teams should track these ballots closely: the outcome will shape how imaging data exchange and health data API standards are defined across the 27 Member States.
