: MedicationAdministration Cumulative Duration example - JSON Representation

Raw json | Download

// 
This example MedicationAdministration models QDM Medication, Administered. 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:
startDate + therapeuticDuration
startDate + 14 days

The therapeuticDuration is likely measure specific, though could potentially be established for
any drug and distributed as a CodeSystem supplement.
It is defaulted to 14 days in the CumulativeMedicationDurationFHIR4.cql library

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