This profile sets minimum expectations for an Encounter resource that is used to record, search, and fetch basic encounter information for a patient. It is based on the[AU Core Encounter](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-encounter.html)profile and identifies the additional constraints, extensions, vocabularies and value sets that**SHALL**be present in the Encounter resource when conforming to this profile. 

### Profile Specific Implementation Guidance

* See the general [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.

Obligations for AU Core actors ([AU Core Requester](https://build.fhir.org/ig/hl7au/au-fhir-core/ActorDefinition-au-core-actor-requester.html) and [AU Core Responder](https://build.fhir.org/ig/hl7au/au-fhir-core/ActorDefinition-au-core-actor-responder.html)) inherited from [AU Core Encounter](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-encounter.html) currently render in the profile view. This is a tooling limitation, and only the AU eRequesting actor obligations should be applied. See [Zulip discussion](https://chat.fhir.org/#narrow/channel/215610-shorthand/topic/Sushi.20merging.20profile.20extension.20with.20parent.20content/with/545567478) for more information.

### Formal Views of Profile Content

 [Description of Profiles, Differentials, Snapshots and how the different presentations work](http://build.fhir.org/ig/FHIR/ig-guidance/readingIgs.html#structure-definitions). 

 

Other representations of profile: [CSV](StructureDefinition-au-erequesting-encounter.csv), [Excel](StructureDefinition-au-erequesting-encounter.xlsx), [Schematron](StructureDefinition-au-erequesting-encounter.sch) 

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the [AU eRequesting CapabilityStatements](capability-statements.md) for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described [here](http://hl7.org/fhir/R4/search.html) and the syntax used to describe AU eRequesting interactions is defined [here](https://build.fhir.org/ig/hl7au/au-fhir-core/general-guidance.html#readsearch-syntax).

Any search parameter defined in FHIR may be 'allowed' by the system unless explicitly marked as "**SHALL NOT**".

* Parameter(s): _id
  * Server Conformance: **SHALL**
  * Placer Conformance: **MAY**
  * Filler Conformance: **MAY**
  * Patient Conformance: **MAY**
  * Type(s): `token`
  * Requirements (when used alone or in combination): 

#### Search Parameters:

The following search parameters and search parameter combinations are supported. Conformance obligations are detailed in the table above.

1. **[`_id`](https://hl7.org/fhir/R4/encounter.html#search)**search parameter`GET [base]/Encounter?_id=[id]`Example:
1. GET [base]/Encounter?_id=987654

**Implementation Notes:** Fetches a bundle with the requested Encounter, instead of just the resource itself, and allows for the inclusion of additional search parameters such as _include, _revinclude, or _lastUpdated ([how to search by id of the resource](https://hl7.org/fhir/r4/search.html#id))
