Encounter
Overview
The Encounter resource provides admissions or visits during which health care services were provided to a patient. An encounter has a class to distinguish between different health care settings such as inpatient, outpatient, emergency, and so on. A patient may have one medical record number with multiple encounter numbers per facility or organization. There is substantial variance between organizations in the definition of an encounter and what events are aggregated together to constitute an encounter.
The following fields are returned if valued:
- Encounter ID
- Encounter identifier (eg: FIN)
- Status
- Class
- Type
- Priority
- Patient
- Participants:
- Start/end time of the encounter
- Discharge disposition
- Reason for visit
- Location
- Organization
- Hospitalization:

Encounter Combines Example
Cerner Millennium supports the ability to logically merge an encounter record into another encounter record when both records are describing the same encounter. This is known
as an encounter combine. If necessary, this merging can later be undone by performing an encounter uncombine. When the requested encounter record has been combined into another
record, an inactive encounter entry is returned which has a reference to the current encounter entry in the partOf
field. Entries for combined encounters will only be returned when retrieving
the entries directly by ID. They will not be returned when searching with other parameters.
