An order for both supply of the medication and the instructions for administration of the medication to a patient. The resource is called "MedicationOrder" rather than "MedicationPrescription" to generalize the use across inpatient and outpatient settings as well as for care plans, etc.

4.13.1 Scope and Usage 4.24.1 Scope and Usage This resource covers all orders for medications for a patient. This includes in-patient medication orders as well as community orders (whether filled by the prescriber or by a pharmacy). It also includes orders for over-the-counter medications (e.g. Aspirin), total parenteral nutrition and diet/ vitamin supplements. It may be used to support the order of medication-related devices. It is not intended for use in prescribing particular diets, or for ordering non-medication-related items (eye-glasses, supplies, etc.)

MedicationOrder An order for both supply of the medication and the instructions for administration of the medicine to a patient. An order for both supply of the medication and the instructions for administration of the medicine to a patient.
MedicationDispense Provision of a supply of a medication with the intention that it is subsequently consumed by a patient (usually in response to a prescription). Provision of a supply of a medication with the intention that it is subsequently consumed by a patient (usually in response to a prescription).
MedicationAdministration When a patient actually consumes a medicine, or it is otherwise administered to them When a patient actually consumes a medicine, or it is otherwise administered to them
MedicationStatement This is a record of medication being taken by a patient, or that the medication has been given to a patient where the record is the result of a report from the patient, or another clinician. A medication statement is not a part of the prescribe->dispense->administer sequence but is a report that such a sequence (or at least a part of it) did take place resulting in a belief that the patient has received a particular medication.
