The HL7 Europe FHIR Base and Core IG is a foundational set of FHIR profiles that provide a consistent framework for healthcare data exchange across Europe, supporting the European Health Data Space (EHDS) by defining reusable ‘Base’ (flexible) and ‘Core’ (more constrained) profiles for common elements, ensuring interoperability while aligning with international standards like the International Patient Summary. The version 2.0.0 has been developed with the support of the Xt-EHR Joint Action, which provided expertise and alignment with European health policy priorities.

This STU2 version 2.00 represents a major update of the HL7 Europe Base and Core FHIR IGs and includes:

• New profiles for: Flag (Alert), AllergyIntolerance, Condition, Procedure, Medication, MedicationStatement, MedicationRequest, Immunization, Composition, DiagnosticReport, and Observation (Generic Medical Test Results)
• Updated references to the latest published Xt-EHR logical models
• New Model-to-Profile maps
