This profile sets minimum expectations for a MedicationStatement resource in the context of a patient summary in an Australian context. It is based on the AU Core MedicationStatement profile, and applies the additional requirements from MedicationStatement (IPS).

See Comparison With Other National and International IGs for a comparison between AU Patient Summary (AU PS) profiles and profiles in other implementation guides.

### Profile Specific Implementation Guidance

- See the guidance on implementing the MedicationStatement resource in AU Core.
- Implementers populating `MedicationStatement.reasonReference` with DiagnosticReport (IPS) are recommended to consider the corresponding AU Base DiagnosticReport profile as guidance for that resource type in an Australian healthcare context.
- When populating `MedicationStatement.medicationCodeableConcept` producers SHALL correctly populate `MedicationStatement.medicationCodeableConcept.coding` with either a code from Australian Medication or PBS Item Codes, or both, if a coded value is known and MAY populate with a code from another code system.
  - Producers MAY populate with only text if no coded value is known.
- The MedicationStatement resource can represent the clinical indication as a code with `MedicationStatement.reasonCode`, or a reference with `MedicationStatement.reasonReference` to a Condition or other resource.
  - Although both are marked as Must Support, producers are not required to support both a code and a reference, but they SHALL support at least one of these elements
  - A consumer SHALL support both elements
- To represent that a patient is not currently taking any medications, the code SNOMED CT 787481004 |No known medications| is used in `MedicationStatement.medicationCodeableConcept`:
  - `MedicationStatement.status` is set to "active"
  - `MedicationStatement.effectiveDateTime` is the period the statement was true or date/time the statement was current
  - A Medication resource referenced in `MedicationStatement.medicationReference` SHALL NOT be used
  - Implementers need to be aware than an IPS document conforming to 1.0.0 or 1.1.0 may provide instead the IPS preferred concept "no-known-medications". The IPS concept "no-known-medications" has been removed from later versions of IPS and replaced with SNOMED CT 787481004 |No known medications|. The concept "no-known-medications" SHOULD NOT be used when producing AU PS compliant data, but receiving systems may still encounter it in IPS documents.

The additional obligation on `MedicationStatement.effectiveDateTime` for AU PS Producer is SHOULD:able-to-populate. This obligation is in addition to the obligation of SHALL:populate-if-known. There is no additional obligation for AU PS Consumer, the obligations of SHALL:handle and SHOULD:display apply.

This additional obligation is present in the underlying structure but due to a tooling limitation is not currently rendered in the Formal Views of Profile Content. See Zulip discussion for more information.

Examples for this Profile: Bundle/aups-basicsummary, Bundle/aups-noknownx, Bundle/aups-referral-endoconsult-autogen and Bundle/aups-referral-endoconsult-curated
