Resource Profile: Profile_R2_Observation_R5

This cross-version profile allows DSTU2 Observation content to be represented via FHIR R5 Observation resources.

Usages:

• Refer to this Profile: DSTU2: One or more sets of investigations (signs, symptions, etc.) (new), DSTU2: Additional clinical information additional types, DSTU2: Code or observation that resulted from goal additional types and DSTU2: detail additional types

You can also check for usages in the FHIR IG Statistics
