Dose Value

First, the main Dosage is determined as follows (from the dosageInstruction element for MedicationRequest, or dosage element for MedicationStatement):

• If there is exactly one Dosage where sequence is 1, then use that Dosage

• Otherwise use the first Dosage in the list

Then, we inspect the main Dosage and retrieve:

doseAndRep[0].doseQuantity.value

Dose Units

First, the main Dosage is determined as follows (from the dosage element):

• If there is exactly one Dosage where sequence is 1, then use that Dosage

• Otherwise use the first Dosage in the list

Then, we inspect the main Dosage and retrieve:

doseAndRep[0].doseQuantity

If this Quantity has a code, no unit and no system, then it is considered to contain a PKB-assigned code.

Otherwise, we inspect the first Dosage (which might differ from the previously determined main Dosage) and inspect doseAndRep[0].doseQuantity for the http://fhir.patientsknowbest.com/structuredefinition/dose-units extension.
