AU eRequesting Implementation Guide
1.0.0-ci-build - CI Build

AU eRequesting Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ci-build built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7au/au-fhir-erequesting/ and changes regularly. See the Directory of published versions

## Resource Profile: AU eRequesting CommunicationRequest ( Abstract )

Official URL: http://hl7.org.au/fhir/ereq/StructureDefinition/au-erequesting-communicationrequest | Version: 1.0.0-ci-build
Standards status: Draft | Maturity Level: 1 | Computable Name: AUeRequestingCommunicationRequest

This profile sets minimum expectations for CommunicationRequest resources that are used to record, search, and fetch information about a communication request to be performed. It is based on the CommunicationRequest resource and identifies the additional constraints, extensions, vocabularies and value sets that SHALL be present in the CommunicationRequest when conforming to this profile.

### Profile Specific Implementation Guidance

- This abstract profile provides a shared base that is common across communication requests. It is not intended for direct implementation. Where a CommunicationRequest profile is defined for a specific purpose that profile SHALL be used:
  - Communication requests about providing a copy of the report to a patient or clinician SHALL use the AU eRequesting CommunicationRequest CopyTo profile
  - Communication requests about communication with a patient from a filler SHALL use the AU eRequesting CommunicationRequest Patient profile
  - Communication requests about communication from a filler to a clinical provider to notify them of urgent results SHALL use the AU eRequesting CommunicationRequest Urgent Provider profile

Usages:

- Derived from this Profile: AU eRequesting CommunicationRequest CopyTo, AU eRequesting CommunicationRequest Patient and AU eRequesting CommunicationRequest Urgent Provider

You can also check for usages in the FHIR IG Statistics

Changes since version 1.0.0-ballot:

- The resource metadata has changed (description)
- The data elements list has changed
- One or more text definitions, invariants or bindings have changed

### 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]/CommunicationRequest?_id=[id]`

   Example:

   1. GET [base]/CommunicationRequest?_id=2169591

   Implementation Notes: Fetches a bundle with the requested CommunicationRequest, 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)
