Represents the result of evaluations (measurements, tests, or questions) that have been performed. Observation has a value representing the result (answer), or an ExceptionValue indicating why the value is not present. The subject of a finding can be the entire patient, or an entity such as a location body structure, intervention, or condition. Things observed about the subject can include social and behavioral factors, subjective and objective observations, and assessments.
This profile builds on US Core Results Profile.
