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

The MedicationRequest and MedicationNotRequested profiles represent the positive and negative statements for a medication order. To ensure instances retrieved meet positive intent, applications should check the status and doNotPerform elements as illustrated in this example:

define MedicationRequest:
  [MedicationRequest] R
    where R.status in { 'active', 'on-hold', 'completed', 'draft' }
      and R.doNotPerform is not true

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'
      and Antithrombotic.doNotPerform is not true

See the patterns page for implementation and usage patterns.
