MedicationRequest
An order or request for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationRequest" rather than "MedicationPrescription" or "MedicationOrder" to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.
These interaction paths describe standard FHIR R4 patterns. Availability can depend on the API capabilities enabled for your Ovok project.
