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 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 in AU Core Encounter.

Obligations for AU Core actors (AU Core Requester and AU Core Responder) inherited from AU Core Encounter currently render in the profile view. This is a tooling limitation, and only the AU eRequesting actor obligations should be applied. See Zulip discussion for more information.

Usages:

- Refer to this Profile: AU eRequesting Diagnostic Request
- Examples for this Profile: Encounter/gp-consult-finger-pain, Encounter/gp-consultation and Encounter/obsgynaeclinic
- CapabilityStatements using this Profile: AU eRequesting Filler CapabilityStatement, AU eRequesting Patient CapabilityStatement, AU eRequesting Placer CapabilityStatement and AU eRequesting Server CapabilityStatement

You can also check for usages in the FHIR IG Statistics

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU eRequesting CapabilityStatements for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described here and the syntax used to describe AU eRequesting interactions is defined here.

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

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

#### Search Parameters:

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

1. `_id` 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)
