## Resource Profile: QICore Medication Prohibited

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-medicationprohibited | Version: 7.0.2
Standards status: Trial-use | Maturity Level: 4 | Computable Name: QICoreMedicationProhibited

Negation profile of MedicationRequest for decision support/quality metrics. Indicates a proposal, plan, or order not to provide a medication.

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
Must Have:

- subject: (QI) Who or group medication request is for
- authoredOn: (QI) When request was initially authored
- status: (QI) active | on-hold | cancelled | completed | stopped | draft
- intent: (QI) proposal | plan | order | original-order | reflex-order | filler-order | instance-order | option
- medication[x]: (QI) Medication to be taken

QI Elements:

- doNotPerform: (QI) True if medication was not requested
- requester: (QI) Who/What requested the Request
- extension(medicationAdherence): (QI) Reported adherence to prescribed medication instructions.
- reasonCode: (QI) Reason or indication for not ordering the medication
- encounter: (QI) Encounter created as part of encounter/admission/stay
- dispenseRequest: (QI) Medication supply authorization
- reasonReference: (QI) QI-Core Condition or Observation that supports the prescription
- dosageInstruction: (QI) How medication should be taken
- reported[x]: (QI) Reported rather than primary record

Primary code path: medication
(PCPath) This element is the primary code path for this resource CQL Retrieve
Usage

The MedicationRequest profile defines the conformance expectations for a MedicationRequest, regardless of whether it is a positive or negative statement. The MedicationRequested and MedicationNotRequested profiles represent the positive and negative statements for a medication order.

To create an expression indicating the existence of a medication request, use the profile QICoreMedicationRequested; to specifically request information that a MedicationRequest intentionally did not occur for a medical, patient or system reason, use the profile QICoreMedicationProhibited.

The following expression retrieves instances meet measure intent for exclusion:

    define "Reason for Not Ordering Antithrombotic":
      ["MedicationProhibited": "Antithrombotic Therapy"] NoAntithromboticDischarge
        where (NoAntithromboticDischarge.reasonCode in "Medical Reason"
          or NoAntithromboticDischarge.reasonCode in "Patient Refusal")
          and (NoAntithromboticDischarge.isCommunity() or NoAntithromboticDischarge.isDischarge())
          and NoAntithromboticDischarge.intent = 'order'

For a more complete discussion of representation of negation within QI-Core and quality improvement artifacts, see the Negation in QI-Core topic.

See the patterns page for implementation and usage patterns.

### Examples

Negation Example using Valueset | Medication not indicated; indicates that none of the medications in the given `codeOptions` value set were requested.
Negation Example using code | Medication not indicated; indicates that the medication specified by code was not requested.
