Australian CVD Risk Calculator - Local Development build (vIteration3) built by the FHIR (HL7® FHIR® Standard) Build Tools. See the Directory of published versions

## Resource Profile: CVD Risk Medication

Official URL: https://www.cvdcheck.org.au/fhir/StructureDefinition/CVDRiskMedication | Version: Iteration3
Draft as of 2025-05-19 | Computable Name: CVDRiskMedication
Copyright/Legal: Copyright © 2024+ National Heart Foundation of Australia - All rights reserved. This content is not available under an open source licence.

This profile sets the expectations for a Medication resource for representing medicine information for use by the Aus CVD Risk-i application.

### Profile specific implementation guidance

This profile is derived from AU Core Medication.

It additionally requires medication information to be represented as an Australian Medicines Terminology coding.

Usage:

- Refer to this Resource Profile: CVD Risk Medication Request
- Examples for this Resource Profile: Medication/irbesartan and Medication/simvastatin
- CapabilityStatements using this Resource Profile: Aus CVD Risk Calculator Application and Aus CVD Risk Calculator Launch Server
