This profile sets the expectations for an Observation resource to record a cardiovascular disease risk result as an output of using the Aus CVD Risk-i application.

### Profile specific implementation guidance

- The CVD risk result as a probability percentage will be recorded in `Observation.value[x]`.
- The assessed CVD risk category will be recorded in `Observation.interpretation`. Categories are based on the CVD Risk Guidelines.
- If the assessed category is the result of a re-classification decision made by a user of the CVD Risk Calculator, the CVD risk result will be as follows:

Category | Result | Additional Information
--- | --- | ---
Low Risk | < 5 | Recorded as `valueQuantity` using a `comparator`.
Intermediate Risk | 5 – 9 | Recorded as `valueRange`. FHIR range boundaries are inclusive.
High Risk | ≥ 10 | Recorded as `valueQuantity` using a `comparator`.

Usage:

- Examples for this Resource Profile: Observation/CVDRisk-DS-6-RO and Observation/CVDRisk-ResultReclassifiedIntermediate
- CapabilityStatements using this Resource Profile: Aus CVD Risk Calculator Application and Aus CVD Risk Calculator Launch Server
