HL7 FHIR Profile: Occupational Data for Health (ODH), Release 1 (Standard for Trial Use)

This page is part of the Occupational Data for Health (ODH) FHIR IG (v0.1.0: STU 1 Ballot 1) based on FHIR R3. The current version which supercedes this version is 1.2.0. For a full list of available versions, see the Directory of published versions

ObservationProfile

 

The official URL for this profile is: 

http://hl7.org/fhir/us/odh/StructureDefinition/cimi-statement-Observation

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.

This profile was published on Fri Aug 17 00:00:00 AEST 2018 as a draft by HL7.
