Usage scenarios

The following are supported usage scenarios for this profile:

• Query for a patient’s medication usage (current and historical)
• Record or update a record of a medication the patient may be taking the medication now or has taken the medication in the past or will be taking the medication in the future

Comparison with other national and international specifications

A resource conforming to this profile is conformant to:

• IPA-MedicationStatement
• and MAY be conformant to Medication Statement (IPS) if MedicationStatement.effective[x] is included and patient is supported as MedicationStatement.subject.reference

No equivalent US Core profile.

Conformance in reverse is not guaranteed, i.e. a resource conforming to International Patient Access or International Patient Summary MAY NOT conform to AU Core.

Profile specific implementation guidance

• See the Medicine information section for guidance
• MedicationStatement resources can represent a medication using either a code with MedicationStatement.medicationCodeableConcept, or reference a Medication resource with MedicationStatement.medicationReference.
  • Although both are marked as must support, servers are not required to support both a code and a reference, but they SHALL support at least one of these elements
  • A client application SHALL support both elements
  • When referencing a Medication resource, it is preferred the resource is contained but it may be an external resource
• MedicationStatement resources may record medication use that is derived from other records such as a MedicationRequest or MedicationDispense. In this case source system identifiers SHOULD be included as AU Local Prescription Identifier, AU ETP Prescription Identifier, or AU Local Dispense Identifier to support deduplication across medication resources.
  • See guidance on the construction of an identifier on the relevant Identifier profile page and the section on Business Identifiers in AU Base.

Slices

This structure defines the following Slices:

• The element MedicationStatement.medication[x] is sliced based on the value of type:$this (Closed)
• The element MedicationStatement.medication[x].coding is sliced based on the value of value:system

Maturity: 0

Below is an overview of the mandatory and optional search parameters and combined search parameters. FHIR search operations and the syntax used to describe the interactions is described here.

Any search parameter defined in FHIR may be ‘allowed’ by the system unless explicitly marked as “SHALL NOT”. A few items are marked as MAY in this implementation guide to highlight their potential relevance.

Mandatory Search Parameters

The following search parameters and search parameter combinations SHALL be supported:

1. SHALL support searching using the patient search parameter:
   • SHOULD support these _include parameters: MedicationStatement:medication
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])

   GET [base]/MedicationStatement?patient={Type/}[id] or optionallyGET [base]/MedicationStatement?patient.identifier=[system|][code]

   Example:

   1. GET [base]/MedicationStatement?patient=5678
   2. GET [base]/MedicationStatement?patient=5678&_include=MedicationStatement:medication
   3. GET [base]/MedicationStatement?patient.identifier=http://ns.electronichealth.net.au/id/medicare-number|32788511952
   4. GET [base]/MedicationStatement?patient.identifier=http://ns.electronichealth.net.au/id/hi/ihi/1.0|8003608833357361

   Implementation Notes: Fetches a bundle of all MedicationStatement resources for the specified patient (how to search by reference and how to search by token)

2. SHALL support searching using the combination of the patient and status search parameters:
   • SHOULD support these _include parameters: MedicationStatement:medication
   • SHALL support these _revinclude parameters: Provenance:target
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
   • SHALL support multipleOr search on status (e.g.status={system|}[code],{system|}[code],...)

   GET [base]/MedicationStatement?patient={Type/}[id]&status={system|}[code]{,{system|}[code],...}

   Example:

   1. GET [base]/MedicationStatement?patient=5678&status=active
   2. GET [base]/MedicationStatement?patient=5678&status=active&_include=MedicationStatement:medication

   Implementation Notes: Fetches a bundle of all MedicationStatement resources for the specified patient and status (how to search by reference and how to search by token)

Optional Search Parameters

The following search parameters and search parameter combinations SHOULD be supported:

1. SHOULD support searching using the combination of the patient and effective search parameters:
   • SHOULD support these _include parameters: MedicationStatement:medication
   • SHOULD support chained searching of patient canonical identifier patient.identifier (e.g. patient.identifier=[system|][code])
   • SHALL support these _revinclude parameters: Provenance:target
   • SHALL support these effective comparators: gt,lt,ge,le
   • SHOULD support multipleAnd search on effective (e.g.effective=[date]&effective=[date]]&...)

   GET [base]/MedicationStatement?patient={Type/}[id]&effective={gt|lt|ge|le}[date]{&effective={gt|lt|ge|le}[date]&...}

   Example:

   1. GET [base]/MedicationStatement?patient=5678&effective=ge2020-01-01T00:00:00Z
   2. GET [base]/MedicationStatement?patient.identifier=http://example.org/fhir/mrn|12345&effective=ge2020-01-01T00:00:00Z
   3. GET [base]/MedicationStatement?patient.identifier=http://example.org/fhir/mrn|12345&effective=ge2020-01-01T00:00:00Z&_include=MedicationStatement:medication

   Implementation Notes: Fetches a bundle of all MedicationStatement resources for the specified patient and date. (how to search by reference and how to search by date)
