AU Base Implementation Guide
6.0.0-ci-build - CI Build

AU Base Implementation Guide, published by HL7 Australia. This guide is not an authorized publication; it is the continuous build for version 6.0.0-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-base/ and changes regularly. See the Directory of published versions

## Resource Profile: AU Base MedicationStatement

Official URL: http://hl7.org.au/fhir/StructureDefinition/au-medicationstatement | Version: 6.0.0-ci-build
Standards status: Trial-use | Maturity Level: 2 | Computable Name: AUBaseMedicationStatement

This profile defines a medication statement structure that localises core concepts, including terminology, for use in an Australian context. The purpose of this profile is to provide national level agreement on core localised concepts. This profile does not force conformance to core localised concepts. It enables implementers and modellers to make their own rules, i.e. profiling, about how to support these concepts for specific implementation needs.

### Usage Notes

Profile specific implementation guidance:

- When identifying a medication, this resource can use either a code or refer to a Medication resource.
- If making use of `MedicationStatement.medicationCodeableConcept`, this profile includes coding as:
  - PBS Item Code - Pharmaceutical Benefits Scheme coding, claiming context is not relevant as medicine coding
  - Medication Package Global Trade Item Number - Global Trade Item Number (GTIN) physical product reference
  - AMT Medicines - Australian Medicines Terminology, national drug terminology
  - MIMS Package - commonly used medicine coding
- If a medication is compounded and is a list of ingredients, `MedicationStatement.medicationCodeableConcept` is still present and may contain only the list of ingredients as text in `MedicationStatement.medicationCodeableConcept.text`.
- Where additional medicinal product information is needed, `MedicationStatement.medicationReference` is preferred to `MedicationStatement.medicationCodeableConcept` and use of extensions, see guidance on AU Base Medication.

Potentially useful extensions:

- MedicationStatement: Medication Brand Name
- MedicationStatement: Medication Generic Name

Usages:

- Examples for this Profile: MedicationStatement/example0, MedicationStatement/example1 and MedicationStatement/example2

You can also check for usages in the FHIR IG Statistics

Changes since version 5.0.0:

- The resource metadata has changed (title)
