AU Base Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 6.0.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7au/au-fhir-base/ and changes regularly. See the Directory of published versions

Resource Profile: AU Assertion of No Relevant Finding

This profile provides an observation information structure for asserting a clinical judgement that there are no items of specific interest, (e.g. no current medications or no history of vaccination), for a patient. An assertion of no relevant finding may be used in continuity of care or transfer or care related lists and composition sections.
