: MedicationRequest Cumulative Duration - XML Representation

Raw xml | Download

  <!-- 
This example MedicationRequest models QDM Medication, Order. Cooking with CQL session 49 discusses how to calculate cumulative medication duration:
https://github.com/cqframework/CQL-Formatting-and-Usage-Wiki/blob/master/Source/Cooking%20With%20CQL/49/36_CumulativeMedicationDuration.cql

The cumulative medication duration in this example would be calculated as:
(supply * (1 + refills )) / (dosage * frequency)
(100 * (1 + 2)) / (5 * 3) = 20 days

See the QDM to QI-Core mapping for details regarding QDM data attribute representation in FHIR.
