## Resource Profile: US Quality Core MedicationRequest

Official URL: http://fhir.org/guides/onc/us-quality-core/StructureDefinition/us-quality-core-medicationrequest | Version: 0.5.0
Active as of 2026-05-15 | Computable Name: USQualityCoreMedicationRequest

Profile of MedicationRequest for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

Usage

To create an expression specifically requesting information that a MedicationRequest intentionally did not occur for a medical, patient or system reason, use the profile USQualityCore-Medicationnotrequested.

The following example illustrates the use of the MedicationRequest profile:

    define "Antithrombotic Therapy at Discharge":
      ["MedicationRequest": medication in "Antithrombotic Therapy"] Antithrombotic
        where (Antithrombotic.isCommunity() or Antithrombotic.isDischarge())
          and Antithrombotic.status in { 'active', 'completed' }
          and Antithrombotic.intent = 'order'

See the patterns page for implementation and usage patterns.
