Model Map

EHDS Logical Models to FHIR Profiles Mapping
Ongoing alignment:The models are expected to continue evolving, with updates incorporated into this Implementation Guide to maintain alignment with the EHDS Implementing Acts.

EHDS Logical Models → FHIR Profiles

The Xt-EHR Joint Action defines EHDS logical data models for core clinical and administrative concepts. This Implementation Guide provides HL7 FHIR profiles that realise those models.

The sections below group the EHDS logical models into categories.

Each table shows:

  • the logical model
  • the FHIR datatype or profile(s) used in this IG
  • a link to the detailed element-by-element mapping

† Mapping with additional clarification note below.

Scope Clarifications:
  • The mapping EHDSObservation → MedicalTestResultEuCore does not apply to every kind of Observation. Not all observations are medical test results; for example, social history observations are Observation resources but are outside the MedicalTestResult scope.
  • EHDSDocument is represented as CompositionEuCore when modelling the structured clinical document composition; it is represented as DiagnosticReportEuCore when modelling report-oriented diagnostic content and results.
