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](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-medicationstatement.html) profile, and applies the additional requirements from [MedicationStatement (IPS)](http://hl7.org/fhir/uv/ips/StructureDefinition/MedicationStatement-uv-ips). 

See [Comparison With Other National and International IGs](comparison.md) 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](https://build.fhir.org/ig/hl7au/au-fhir-core/StructureDefinition-au-core-medicationstatement.html#profile-specific-implementation-guidance) in AU Core.
* Implementers populating `MedicationStatement.reasonReference` with [DiagnosticReport (IPS)](https://hl7.org/fhir/uv/ips/STU2/StructureDefinition-DiagnosticReport-uv-ips.html) are recommended to consider the corresponding [AU Base DiagnosticReport](https://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-diagnosticreport.html) 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](https://healthterminologies.gov.au/fhir/ValueSet/australian-medication-1) or [PBS Item Codes](https://build.fhir.org/ig/hl7au/au-fhir-base//ValueSet-pbs-item.html), 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"](https://hl7.org/fhir/uv/ips/STU1/CodeSystem-absent-unknown-uv-ips.html#absent-unknown-uv-ips-no-known-medications). The IPS concept ["no-known-medications"](https://hl7.org/fhir/uv/ips/STU1/CodeSystem-absent-unknown-uv-ips.html#absent-unknown-uv-ips-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"](https://hl7.org/fhir/uv/ips/STU1/CodeSystem-absent-unknown-uv-ips.html#absent-unknown-uv-ips-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](ActorDefinition-au-ps-actor-producer.md) is [SHOULD:able-to-populate](https://hl7.org/fhir/extensions/CodeSystem-obligation.html#obligation-SHOULD.58able-to-populate). This obligation is in addition to the obligation of [SHALL:populate-if-known](https://hl7.org/fhir/extensions/CodeSystem-obligation.html#obligation-SHOULD.58populate-if-known). There is no additional obligation for [AU PS Consumer](ActorDefinition-au-ps-actor-consumer.md), the obligations of [SHALL:handle](https://hl7.org/fhir/extensions/CodeSystem-obligation.html#obligation-SHALL.58handle) and [SHOULD:display](https://hl7.org/fhir/extensions/CodeSystem-obligation.html#obligation-SHOULD.58display) 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](https://chat.fhir.org/#narrow/channel/179252-IG-creation/topic/Obligation.20Extension.20on.20ElementDefinition.2Etype.20not.20rendering) for more information.

For example, if you require form or lot number, then you must reference the Medication resource.\r\n\r\nTo improve global interoperability, IPS strongly encourages the use of a reference to a Medication resource, and medicationCodeableConcept is only recommended for cases where no other information than a simple code is available.\r\n\r\nAU PS does not adopt the IPS guidance that systems should only populate a Medication reference when more information than a simple code is available; either medicationReference or medicationCodeableConcept can be used. Future releases of AU PS, based on implementation experience in Australia may adopt that IPS guidance."
