## Resource Profile: AU Core Encounter

Official URL: http://hl7.org.au/fhir/core/StructureDefinition/au-core-encounter | Version: 1.1.0-preview
Standards status: Trial-use | Maturity Level: 2 | Computable Name: AUCoreEncounter

This profile sets minimum expectations for an Encounter resource to record, search, and fetch basic encounter information for a patient. It is based on the AU Base Encounter profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the Encounter when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

See Comparison with other national and international IGs for a comparison between AU Core profiles and profiles in other implementation guides.

### Usage scenarios

The following are supported usage scenarios for this profile:

- Query for a specific patient encounter
- Query for all patient encounters
- Record or update a patient encounter

### Profile specific implementation guidance

- 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, responders are not required to support both a code and a reference, but they SHALL support at least one of these elements
  - A requester SHALL support both elements

Usage:

- Refer to this Resource Profile: AU Core MedicationRequest and AU Core Procedure
- Examples for this Resource Profile: Encounter/covid-admin-1, Encounter/discharge-1 and Encounter/telehealth
- CapabilityStatements using this Resource Profile: AU Core Requester CapabilityStatement and AU Core Responder CapabilityStatement

Changes since version 1.0.0:

- The resource metadata has changed (description)

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU Core 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 Core interactions is defined here.

Any search parameter defined in FHIR may be ‘allowed’ by the system unless explicitly marked as “SHALL NOT”. A few items are marked as MAY in this implementation guide to highlight their potential relevance.

Parameter(s) | Conformance | Type(s) | Requirements (when used alone or in combination)
--- | --- | --- | ---
patient | SHALL | `reference` | The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both. The requester SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile. The responder SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile.
patient+date | SHALL | `reference`+`date` |
patient+class | SHOULD | `reference`+`token` |
patient+location | SHOULD | `reference`+`reference` |
patient+status | SHOULD | `reference`+`token` |
class | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both.
date | MAY | `date` | A requester SHALL provide a value precise to the second + time offset. A responder SHALL support a value precise to the second + time offset. The requester SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The responder SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The requester SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`. The responder SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`.
location | MAY | `reference` | The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both.
status | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both. The requester SHALL support `multipleOr`.The responder SHALL support `multipleOr`.

#### Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported:

1. SHALL support searching using the `patient` search parameter:
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)

   `GET [base]/Encounter?patient={Type/}[id]` or optionally `GET [base]/Encounter?patient.identifier=[system|][code]`

   Example:

   1. GET [base]/Encounter?patient=5678
   2. GET [base]/Encounter?patient.identifier=http://ns.electronichealth.net.au/id/medicare-number|32788511952
   3. GET [base]/Encounter?patient.identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833357361

   Implementation Notes: Fetches a bundle of all Encounter resources for the specified patient (how to search by reference and how to search by token)

2. SHALL support searching using the combination of the `patient` and `date` search parameters:
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)
   - SHALL support these `date` comparators: `gt,lt,ge,le`
   - SHOULD support multipleAnd search on `date` (e.g.`date=[date]&date=[date]]&...`), and if multipleAnd is supported, SHALL support the search comparators `gt,lt,ge,le`

   `GET [base]/Encounter?patient={Type/}[id]&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}`

   Example:

   1. GET [base]/Encounter?patient=5678&date=ge2020-01-01T00:00:00Z

   Implementation Notes: Fetches a bundle of all Encounter resources for the specified patient and date (how to search by reference and how to search by date)

#### Optional Search Parameters:

The following search parameters and search parameter combinations SHOULD be supported:

1. SHOULD support searching using the combination of the `patient` and `class` search parameters:
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)

   `GET [base]/Encounter?patient={Type/}[id]&class={system|}[code]`

   Example:

   1. GET [base]/Encounter?patient=5678&class=http://terminology.hl7.org/CodeSystem/v3-ActCode|AMB

   Implementation Notes: Fetches a bundle of all Encounter resources for the specified patient and class (how to search by reference and how to search by token)

2. SHOULD support searching using the combination of the `patient` and `location` search parameters:
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)

   `GET [base]/Encounter?patient={Type/}[id]&location={Type/}[id]`

   Example:

   1. GET [base]/Encounter?patient=5678&location=Location/vic-hospital

   Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and location (how to search by reference)

3. SHOULD support searching using the combination of the `patient` and `status` search parameters:
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)
   - SHALL support multipleOr search on `status` (e.g.`status={system|}[code],{system|}[code],...`)

   `GET [base]/Encounter?patient={Type/}[id]&&status={system|}[code]{,{system|}[code],...}`

   Example:

   1. GET [base]/Encounter?patient=5678&status=finished

   Implementation Notes: Fetches a bundle of all Encounter resources matching the specified patient and status (how to search by reference) and how to search by token).
