## Resource Profile: AU Core MedicationStatement

Official URL: http://hl7.org.au/fhir/core/StructureDefinition/au-core-medicationstatement | Version: 3.0.0-ballot1
Standards status: Trial-use | Maturity Level: 2 | Computable Name: AUCoreMedicationStatement

This profile sets minimum expectations for a MedicationStatement resource to record, search, and fetch summary statements of medication use associated with a patient. It is based on the AU Base MedicationStatement profile and identifies the additional mandatory core elements, extensions, vocabularies and value sets that SHALL be present in the MedicationStatement when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context.

See Comparison with other national and international IGs for a comparison between AU Core profiles and profiles in other implementation guides.

### Usage Scenarios

The following are supported usage scenarios for this profile:

- Query for a patient's medication usage (current or historical)
- Record or update stated medication usage for a patient

### Profile Specific Implementation Guidance

- See the Medicine Information page for guidance on how medicinal product identification can be structured in FHIR conformant to AU Core.
- MedicationStatement resources can represent a medication using either a code as `MedicationStatement.medicationCodeableConcept`, or reference a Medication resource using `MedicationStatement.medicationReference`.
  - Responders are not required to support both a code and a reference, but they SHALL support at least one of these methods
  - When referencing a Medication resource, it is preferred the resource is contained but it may be an external resource
  - If an external reference to a Medication resource is used, the responder SHALL support the `_include` parameter for searching this element
  - A requester SHALL support all methods
- When populating `MedicationStatement.medicationCodeableConcept` responders 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.
  - Responders 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, responders are not required to support both a code and a reference, but they SHALL support at least one of these elements
  - A requester 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.effective[x]` 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

Usages:

- Examples for this Profile: MedicationStatement/active-bisoprolol, MedicationStatement/completed-bactrim, MedicationStatement/completed-chloramphenicol and MedicationStatement/previous-use-diflucan
- CapabilityStatements using this Profile: AU Core Requester CapabilityStatement and AU Core Responder CapabilityStatement

You can also check for usages in the FHIR IG Statistics

Changes since version 2.0.0:

- The resource metadata has changed (description)

Summary

Must-Support: 13 elements

Structures

This structure refers to these other structures:

- AU Core Medication (http://hl7.org.au/fhir/core/StructureDefinition/au-core-medication)
- AU Core Patient (http://hl7.org.au/fhir/core/StructureDefinition/au-core-patient)
- AU Core Condition (http://hl7.org.au/fhir/core/StructureDefinition/au-core-condition)
- AU Core DiagnosticReport (http://hl7.org.au/fhir/core/StructureDefinition/au-core-diagnosticreport)

Slices

This structure defines the following Slices:

- The element 1 is sliced based on the value of MedicationStatement.medication[x] (Closed)
- The element 1 is sliced based on the value of MedicationStatement.medication[x].coding

Maturity: 2

Other representations of profile: CSV, Excel, Schematron

### Notes:

Below is an overview of the mandatory and optional search parameters and combined search parameters. See the AU Core CapabilityStatements for a complete list of supported RESTful interactions for this IG.

FHIR search operations are described here and the syntax used to describe AU Core interactions is defined 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.

Parameter(s) | Conformance | Type(s) | Requirements (when used alone or in combination)
--- | --- | --- | ---
patient | SHALL | `reference` | The requester SHALL provide at least an id value and MAY provide both the Type and id values. The responder SHALL support both. The requester SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile. The responder SHOULD support chained search patient.identifier using IHI, Medicare Number, and DVA Number identifiers as defined in the AU Core Patient profile.
patient+status | SHALL | `reference`+`token` |
patient+effective | SHOULD | `reference`+`date` |
_id | SHOULD | `token` |
effective | MAY | `date` | A requester SHALL provide a value precise to the second + time offset. A responder SHALL support a value precise to the second + time offset. The requester SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The responder SHALL support these search comparators `gt`, `lt`, `ge`, `le`. The requester SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`. The responder SHOULD support `multipleAnd`, and if `multipleAnd` is supported, SHALL support the search comparators `gt`, `lt`, `ge`, `le`.
status | MAY | `token` | The requester SHALL provide at least a code value and MAY provide both the system and code values. The responder SHALL support both. The requester SHALL support `multipleOr`. The responder SHALL support `multipleOr`.

#### 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`
   - SHOULD support chained searching of patient canonical identifier `patient.identifier` (e.g. `patient.identifier=[system|][code]`)

   `GET [base]/MedicationStatement?patient={Type/}[id]` or optionally `GET [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`
   - 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 `_id` search parameter:
   - SHOULD support these `_include` parameters: `MedicationStatement:medication`

   `GET [base]/MedicationStatement?_id=[id]`

   Example:

   1. GET [base]/MedicationStatement?_id=2169591
   2. GET [base]/MedicationStatement?_id=2169591&_include=MedicationStatement:medication

   Implementation Notes: Fetches a bundle with the requested MedicationStatement, instead of just the resource itself, and allows for the inclusion of additional search parameters such as _include, _revinclude, or _lastUpdated (how to search by id of the resource)

2. 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 `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)
