This profile sets minimum expectations for an Encounter resource in the context of a patient summary in an Australian context. It is based on the [AU Core Encounter](https://hl7.org.au/fhir/core/2.0.0/StructureDefinition-au-core-encounter.html) profile, and applies the additional constraints for use in a patient summary context consistent with the profiling conventions of [IPS](https://hl7.org/fhir/uv/ips/2.0.1/). 

See [Comparison With Other National and International IGs](comparison.md) for a comparison between AU Patient Summary (AU PS) profiles and profiles in other implementation guides.

### Profile Specific Implementation Guidance

* See the [guidance on implementing the Encounter resource](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-encounter.html#profile-specific-implementation-guidance) in AU Core.
* The Encounter resource can represent a clinical indication with `Encounter.reasonCode`, or a reference with `Encounter.reasonReference` to a Condition or other resource. 
* Although both are marked as **Must Support**, producers are not required to support both a code and a reference, but they **SHALL** support **at least one** of these elements
* A consumer **SHALL** support both elements
 

**Examples for this Profile**: [Bundle/aups-gpvisit-retrieval](Bundle-aups-gpvisit-retrieval.md)

**Usages:**

* Use this Profile: [AU PS Bundle](StructureDefinition-au-ps-bundle.md)
* Refer to this Profile: [AU PS MedicationRequest](StructureDefinition-au-ps-medicationrequest.md) and [AU PS Procedure](StructureDefinition-au-ps-procedure.md)
