Observations

Data Element

Information from the submission form

Observation Performer
Who was responsible for asserting the observed value as "true".

Many observations will be asserted by a clinician in the care of a patient, but this data element also explicitly allows record of patients, caregivers, and other entities as the source. Such information is crucial for understanding context for observations derived from patient reported outcomes measures.

Data Type: Reference (Practitioner, PractitionerRole, Organization, CareTeam, Patient, RelatedPerson). This data element may be a pointer into a record in another table/structure that contains more metadata about the performer. In other contexts, it may be a data type that carries all of the requisite identifying information "inline", such as the XCN (Extended Composite ID Number and Name for Persons) data type used in HL7 v2 OBX-16.
