MedicationOrder

This topic describes information for the MedicationOrder resource.

To interact with the REST endpoints in the MedicationOrder resource, see MedicationOrder.

Overview

The MedicationOrder resource provides orders for all medications with administration instructions for a patient in both the inpatient and outpatient settings (orders or prescriptions filled by a pharmacy and discharge medication orders). This resource does not include historical or home medications documented or reported to have been taken by the patient, significant other, or another provider.

If the medication order represents a prescription the patient takes at home, then the start, stop, and other information may not be a representation of when the medication was taken. For example, the system may not know if the patient ever filled or took the prescribed medication, or when the prescription was filled.
