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.
