description | 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://build.fhir.org/ig/hl7au/au-fhir-core/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/STU2/). |
