## Resource Profile: AU Core Medication

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

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

In AU Core a Medication resource is used within the context of a referencing resource: MedicationAdministration, MedicationDispense, MedicationRequest, or MedicationStatement resource.

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 medications associated with a patient referenced by another resource
- Record or update a medication associated with a patient referenced by another resource
- Read medications associated with a patient referenced by another resource

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

### Profile specific implementation guidance

- See the Medicine Information page for guidance on how medicinal product identification can be structured in FHIR conformant to AU Core.

Usage:

- Refer to this Resource Profile: AU Core MedicationRequest and AU Core MedicationStatement
- Examples for this Resource Profile: Medication/1active-ingredient, Medication/2active-ingredients and Medication/simvastatin
- 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)
