HL7 Europe and IHE-Europe open coordinated ballots for European FHIR Implementation Guides developed jointly in the EURIDICE collaboration
Brussels, 27 March 2026 – HL7 Europe and IHE-Europe announced the opening of two new ballots for European FHIR Implementation Guides (IGs) for the EHDS. The two IGs, namely for the Imaging Study Report and the EU Health Data API, have been developed jointly by the two organisations as part of their EURIDICE collaboration.
Anyone is invited to submit comments (instructions are available below). At the same time, official ballot votes may only be cast by HL7 Europe affiliates (for the HL7 part) and by the National Deployment Committees and identified contacts (for the IHE-Europe part). The deadline for ballots and comments is 30 April 2026. The IGs under ballot include:
- HL7 Europe Imaging Study Report FHIR Implementation Guide (R4)
Implementation Guide: https://hl7.eu/fhir/imaging/1.0.0-ballot/
Ballot type: STU1 Ballot (1.0.0-ballot)
Submit comments: https://jira.hl7.org/
Cast vote: https://confluence.hl7.org/x/CgZRGg - EU Health Data API FHIR Implementation Guide (1.0.0-ballot)
Implementation Guide: https://hl7.eu/fhir/health-data-api/1.0.0-ballot
Submit comments: https://jira.hl7.org/
Cast vote: https://confluence.hl7.org/x/iwVRGg
Both of these FHIR IGs define sets of EHR functionalities that meet the Interoperability Component requirements of the European Health Data Space regulation ((EU) 2025/327). They describe how existing IHE profiles and other specifications can be used to enable secure exchange of electronic health data between systems, and show how these EHR functionalities can be used in real-world data exchange for EHDS use cases.
Both IGs were developed in the EURIDICE collaboration, a joint HL7 Europe and IHE-Europe initiative focused on creating well-architected, implementable and testable specifications offered to the European Commission for being referenced in the EHDS Implementing Acts. These technical specifications seek to combine HL7’s FHIR expertise with the IHE methodology, and facilitate alignment with EU-funded projects, national priorities, and Standards Developing Organization (SDO).
