11.1 Resource MedicationRequest - Content

Pharmacy Work GroupMaturity Level: 3 Trial UseSecurity Category: Patient Compartments: Encounter, Patient, Practitioner

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.

11.1.1 Scope and Usage

This resource covers all type of orders for medications for a patient. This includes inpatient 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 (eyeglasses, supplies, etc.). In addition, the MedicationRequest may be used to report orders/request from external systems that have been reported for informational purposes and are not authoritative and are not expected to be acted upon (e.g. dispensed or administered).

The MedicationRequest resource is a "request" resource from a FHIR workflow perspective - see Workflow Request.

The MedicationRequest resource allows requesting only a single medication. If a workflow requires requesting multiple items simultaneously, this is done using multiple instances of this resource. These instances can be linked in different ways, depending on the needs of the workflow. For guidance, refer to the Request pattern

11.1.2 Boundaries and Relationships

The MedicationRequest resource is used to request or order medication for a subject. It may also be used to report a medication request or order from one organization or source to another. When requesting supplies or devices when there is a patient focus or instructions regarding their use, SupplyRequest or DeviceRequest should be used instead. When reporting on the usage of a medication by a patient, the MedicationStatementt resource should be used.

The Medication domain includes a number of related resources

MedicationRequest 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).
MedicationAdministration 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.

11.1.3 References

This resource is referenced by CarePlan, Claim, DiagnosticReport, ExplanationOfBenefit, MedicationAdministration, MedicationDispense, itself, MedicationStatement, Observation and ServiceRequest.

This resource implements the Request pattern.

11.1.4.2 Dosage Instructions

Free text dosage instructions can be used for cases where the instructions are too complex to code. The content of this attribute does not include the name or description of the medication. When coded instructions are present, the free text instructions may still be present for display to humans taking or administering the medication. It is expected that the text instructions will always be populated. If the dosage.timing attribute is also populated, then the dosage.text should reflect the same information as the timing.
