Logical Models

EHDS Logical Data Models

Logical data models (or information models) for the European Health Data Space (EHDS) have been developed by the Xt-EHR Joint Action, which published version 1.0.0 as its end-of-project release. These models are the basis for designing the European electronic health record exchange format (E-EHRxF).

They were developed from the data sets described in the eHealth Network (eHN) Guidelines and refined to be machine-processable and consistent with each other.

This Implementation Guide (IG) aligns with the EHDS logical models and provides HL7 FHIR profiles that realise the requirements identified in these models.

Below is a simplified representation of the laboratory report data set of the eHN guidelines, from which the EHDS logical models were developed. The data set comprises several basic parts, as visualised in the diagrams below.
