This class describes the services that an Individual Provider may provide at different locations within the context of his/her affiliation with an Organizational Provider. This class is called Provider Role because it is similarly named in FHIR, and because it describes the role the Individual Provider is playing at a particular Organizational Provider’s facility (i.e., Service Delivery Location). An Individual Provider may have multiple specialties but only be authorized to use a particular specialty at a particular location. In addition, because this class links an Individual Provider with a location, it is used to link to the providers schedule at that location and to provide a list of electronic endpoints at which the provider can be reached through electronic communications. Note that in FHIR, this resource is used to refer to a Provider without knowing in advance which individual will play this role (e.g, I need a Cardiologist that is associated with this hospital (i.e., it doesn't matter which cardiologist), or accepts my plan, etc.). Thus in FHIR, this resource points to an optional provider and an optional organization. In FHIM, the association between an IndividualProvider and an OrganizationProvider is handled through the NetworkAffiliation class. Thus, the FHIM includes an optional pointer to NetworkAffiliation rather than separate pointers to IndividualProvider and OrganizationProvider.
