Resource Profile: AU Core Medication

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.

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
