AU Base Implementation Guide
6.0.1-ci-build - CI Build

AU Base Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 6.0.1-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/AuDigitalHealth/au-fhir-base/ and changes regularly. See the Directory of published versions

## Resource Profile: AU Base Encounter

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-encounter | Version: 6.0.1-ci-build
Standards status: Trial-use | Maturity Level: 1 | Computable Name: AUBaseEncounter
Copyright/Legal: HL7 Australia© 2018+; Licensed Under Creative Commons No Rights Reserved.

This profile defines an encounter structure that localises core concepts, including terminology, for use in an Australian context. This profile is intended to be applicable for recording details of ambulatory and non-ambulatory patient encounters in an Australian healthcare context. The purpose of this profile is to provide national level agreement on core localised concepts. This profile does not force conformance to core localised concepts. It enables implementers and modellers to make their own rules, i.e. profiling, about how to support these concepts for specific implementation needs.

### Usage Notes

Profile specific implementation guidance:

- To associate a healthcare service with an encounter include FHIR R5 element pre-adoption of `Encounter.participant.actor`. See example Inpatient Encounter.
  - Use the pre-adoption extension URL http://hl7.org/fhir/5.0/StructureDefinition/extension-Encounter.participant.actor.
  - Apply the pre-adoption extension on `Encounter.participant`.

Usages:

- Examples for this Profile: Encounter/example0 and Encounter/example1

You can also check for usages in the FHIR IG Statistics

Changes since version 5.0.0:

- The data elements list has changed
