: MedicationDispense cumulative dose example - JSON Representation

Raw json | Download

// 
This example MedicationDispense models QDM Medication, Dispensed. Cooking with CQL session 53 discusses how to calculate cumulative medication duration:
https://github.com/cqframework/CQL-Formatting-and-Usage-Wiki/blob/master/Source/Cooking%20With%20CQL/53/CumulativeMedicationDurationFHIR.cql

The cumulative medication duration in this example would be calculated as:
supply or (quantity / (dose * dosesPerDay))
30 or (450 / (5 * 3)) = 30 days

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