1.0.0-ballot - ballot 150

This page is part of the EU Health Data API (v1.0.0-ballot: STU1 Ballot 1) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version. For a full list of available versions, see the Directory of published versions

Priority Categories

EHDS defines priority categories of health data for interoperability. Each has a content profile defining the data model, maintained in separate Content IGs.

This API IG defines exchange — the transactions and patterns that systems use to share data. It does not prescribe internal system architecture or design. Systems that choose to comply with EHDS interoperability requirements implement this exchange behavior alongside one or more Content IGs.

Priority Categories and Exchange Patterns

Each priority category pairs a data specification (Content IG) with an exchange pattern (this IG). Systems claiming conformance for a category implement both.

Priority Category Content IG Exchange Pattern API Guidance
Patient Summary HL7 Europe Patient Summary Document exchange (MHD) Patient Summary
Hospital Discharge Report HL7 Europe Hospital Discharge Report Document exchange (MHD) Discharge Report
Medical Test Results HL7 Europe Laboratory Report Document exchange (MHD) Laboratory
Medical Imaging — Report HL7 Europe Imaging Reports Document exchange (MHD) Imaging Report
Medical Imaging — Manifest HL7 Europe Imaging Reports Document exchange (MHD) Imaging Manifest
Individual clinical resources HL7 Europe Core Resource access (IPA) Resource Access

For document search and differentiation by priority category, see Document Exchange.

Medication data and ePrescription/eDispensation: Reading medication resources (MedicationRequest, MedicationStatement) is resource access, handled by this IG. The ePrescription and eDispensation workflow transactions (prescribing, dispensing) are out of scope and handled by IHE MPD.

See the HL7 Europe Implementation Guides registry for the canonical list of Content IGs and their current publication URLs.
