US Meds Implementation Guide STU2 Ballot (version 1.1.0)

D.4.1 StructureDefinition-medicationdispense

This page is part of the US-Medication FHIR IG (v1.1.0: STU 2 Ballot 1) based on FHIR R3. The current version which supercedes this version is 1.2.0. For a full list of available versions, see the Directory of published versions

The MedicationDispense resource can be used to record a medication that has been dispensed for a named person/patient. For more information about the context and usage, refer to the resource page in the FHIR specification. This profile sets minimum expectations for recording, searching and fetching a patient’s MedicationAdministration resource. It identifies which core elements, extensions, vocabularies and value sets SHALL be present in the resource when using this profile.

Example Usage Scenarios:

The following are example usage scenarios:

  • Query for medications that have been dispensed to a particular patient
Mandatory Data Elements and Terminology

The following data-elements are mandatory (i.e data MUST be present). These are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Profile Definition below provides the formal summary, definitions, and terminology requirements.

Each MedicationDispense must have:

  1. a status
  2. a medication
  3. a patient
  4. a date or date range

In addition, a system Must Support.

  1. who dispensed
  2. dosage information

Profile specific implementation guidance:

  • None

D.4.1.2 Quick Start

Below is an overview of the required search and read operations for this profile. See the Conformance requirements for the US Core Server for a complete list of supported RESTful operations and search parameters for this IG.

Summary of Argonaut Search Criteria for StructureDefinition-medicationdispense

GET /MedicationDispense?patient=[id]{&_include=MedicationDispense:medication}

Example:

  • GET /MedicationDispense?patient=14676
  • GET /MedicationDispense?patient=14676&_include=MedicationDispense:medication

Support: Mandatory for server and client to support search by patient. Mandatory for client to support the _include parameter. Optional for server to support the _include parameter.

Implementation Notes: This query searches for all MedicationDispense resources for a patient and returns a Bundle of all MedicationDispense and resources for the specified patient. The server application represents the medication using either an inline code or a contained or external reference to the Medication resource. (how to search by reference), and (how to search by _include).
