Logical Model: Participant2 (CDA Class)

Can be used to represent any other participant that cannot be represented with one of the more specific participants. The participant can be ascribed to a CDA entry, and propagates to nested CDA entries, unless overridden.

Usages:

• Use this Logical Model: Act (CDA Class), Encounter (CDA Class), Observation (CDA Class), ObservationMedia (CDA Class)... Show 5 more, Organizer (CDA Class), Procedure (CDA Class), RegionOfInterest (CDA Class), SubstanceAdministration (CDA Class) and Supply (CDA Class)
