Version:1.4.1
Name:AUCoreWaistCircumference
Title:AU Core Waist Circumference
Status:Draft as of 2025-02-03 04:29:41+0000
Definition:

This profile sets minimum expectations for an Observation resource to record, search, and fetch waist circumference observations with standard coding and units of measure. It is based on the FHIR Vital Signs Profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Observation resource when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.
