U.S. Data Access Framework (DAF) MedicationStatement Profile (Profile)

Scope and Usage

This profile sets expectations for use of the MedicationStatement resource to record summary of active medication information for a patient within the Data Access Framework (DAF) Implementation Guide. This profile identifies which core elements,extensions,vocabularies and value sets must be Supported by DAF actors. For the definition of Supported please refer to DAF FHIR IG. The data elements identified by the profile are based on ONC 2014 Edition S&CC and DAF use cases. The mappings between the ONC 2014 Edition S&CC data elements and DAF data elements are captured in the table below, where the first column identifies the ONC 2014 Edition S&CC data element name, the second column maps the ONC 2014 Edition S&CC data elements to DAF data elements which are derived from ONC 2014 Edition S&CC standards and DAF use cases and lastly the third column identifies the mapping to FHIR resources and attributes.

Meaningful Use Data Element Mapping

The DAFMedicationStatement profile mapping to Meaningful Use data elements and FHIR Resources are as shown below.

Boundaries and Relationships

This profile relies on the following other profiles:

DAFPatient which defines DAF Patient profile is used by DAFMedicationStatement profile to refer to patients.
DAFMedication is used by the this profile to code the medication material(e.g drug).
FHIR Extensibility defines how extensions can be applied to FHIR resources and data types. Specifically the data-absent-reason extension can be used to code data elements with missing information when appropriate. See DAF FHIR IG for additional guidance.

Profile Details

Profiles:
DAFMedicationStatement	Defines constraints and extensions on the MedicationStatement resource for use in querying and retrieving patient's medication information.

Search Parameters

The full list of supported search parameters are can be accessed at DAF Requestor conformance expectations and DAF Responder conformance expectations.

Example Usage Scenarios

The following are example usage scenarios for the DAFMedicationStatement profile:

Query for active medications being taken by a patient
Query for all patients who are taking a particular medication
Query for all patients who are/were taking a particular medication within a particular time period

Profile specific implementation guidance

Implementers need to be mindful of the following during their implementation

Representing No Known Medications: No Known Medications will be represented using the DAFMedicationStatementList profile with no entries.

See DAF FHIR IG for implementation guidance common to all profiles.
