D.13.0 U.S. Data Access Framework (DAF) MedicationStatement Profile

D.13.0.1 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 DAF FHIR IG. 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.

D.13.0.2 Meaningful Use Data Element Mapping

The DAF-MedicationStatement profile mapping to Meaningful Use data elements and FHIR Resources are as shown below.For an overview of how the DAF profiles and data elements were derived from ONC 2014 Edition S&CC please refer to DAF FHIR IG data mapping section.

D.13.0.3 Boundaries and Relationships

This profile relies on the following other profiles:

  • DAF-Patient is used by DAF-MedicationStatement profile to refer to patients.
  • DAF-Medication 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.

D.13.0.4 Content

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