HL7 FHIR Implementation Guide: minimal Common Oncology Data Elements (mCODE), v0.9.1

HL7 FHIR Implementation Guide: minimal Common Oncology Data Elements (mCODE), v0.9.1 FHIR Profiles - Local Development build (v0.9.1). See the Directory of published versions

Observation

 

The official URL for this profile is:

http://mcodeinitiative.org/us/mcode/StructureDefinition/obf-Observation

Represents the result of evaluations (measurements, tests, or questions) that have been performed. Observation has a value representing the result (answer), or an DataAbsentReason indicating why the value is not present. Things observed about the subject can include social and behavioral factors, subjective and objective observations, and assessments. For an Observation, the Code describes the aspect or property of the subject being observed or measured. The Code is the 'question code' that pairs to the 'answer' contained in the Value.

This profile builds on Observation.

This profile was published on Wed Oct 23 00:00:00 EDT 2019 as a draft by The MITRE Corporation.
