NOTE TO BALLOT REVIEWERS:
  • US Core 7.0, and thus QI-Core 7.0, has a new approach to USCDI requirements.
    • As noted in the US Core 7.0 Must Support section, US Core 7.0 no longer highlights mandatory (cardinality 1..* or 1..1) and Must Support elements with a (USCDI) indicator as such items must be supported for interoperability.
    • Those USCDI elements that are not mandatory or Must Support now include an indicator (ADDITIONAL USCDI) in US Core. QI-Core 7.0 does not reference USCDI elements; rather, users should access US Core 7.0 to understand its implementation of USCDI version 4.
  • We invite comments about the approach and suggestions for other options that would also avoid unnecessary noise or reading load to the QI-Core profile representation.
  • Further, QI-Core 7.0 does not discuss USCDI+Quality because at the time of ballot preparation, no published version of USCDI+Quality is available. We seek reviewer advice regarding how QI-Core might address future USCDI+Quality.

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 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.
