This guidance and list underwent Clinical and Technical Assurance during Sprint 6. This is a new content added to UK Core and should undergo review in this STU2 ballot.
The following R5 elements have been agreed as suitable to be included for use with the UK Core Profiles because the use case for pre-adopting an R5 element as an Extension, rather than creating a UK Core specific extension is fully met.
As of 19/05/2023, the package to enable pre-adopted elements to function as per the guidance, is not available. To enable rendering and validation of these pre-adopted elements, we have provided UKCore proxy extensions, as per the current threads on chat.fhir.org, with the R5 canonical urls. These proxy extensions will be retired once the HL7 package is released.
