Resource Profile: AU Core Assertion of No Relevant Finding

This profile sets minimum expectations for an Observation resource to record, search, and fetch observation of clinical assertions that there are no items of interest, e.g. no current medications, for a patient. It is based on the core Observation resource and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Observation when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

Usage:

• Examples for this Resource Profile: Observation/norelevantfinding-1
