This page is part of the HL7 Europe Base and Core (v0.1.0-ballot: Release Ballot 1) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions
This implementation guide has parallel flavours for HL7 FHIR R4 and R5 versions.
This is an R4 IG. None of the features it uses are changed in R4B, so it can be used as is with R4B systems. Packages for both R4 (hl7.fhir.eu.base.r4) and R4B (hl7.fhir.eu.base.r4b) are available.
