This class is included for compatibility with FHIR. It is used to convey the state of the Encounter or Episode of Care over time. This information is expected to be easily computable from the source system, and might not necessarily be persisted in a structure like this. Nevertheless, this structure may be useful as a standardized structure when exchanging this information. "The status history permits the encounter resource to contain the status history without needing to read through the historical versions of the resource, or even have the server store them." - HL7 FHIR, Encounter.statusHistory "The history of statuses that the EpisodeOfCare has been through (without requiring processing the history of the resource)." - HL7 FHIR, EpisodeOfCare.statusHistory
