Medication Request

It indicates 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 “Medication Request” rather than “Medication Prescription” or “Medication Order” to generalize the use across inpatient and outpatient settings, including care plans, etc., and to harmonize with workflow patterns.

Medication Request 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 Medication Request 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 Medication Request resource is a “request” resource from a Fast Healthcare Interoperability Resources (FHIR) workflow. The Medication Request 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.

The Medication Request 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, Supply Request or Device Request should be used instead. When reporting on the usage of a medication by a patient, the Medication Statementt resource should be used.

Data Fields

Name Description Type Constraints
Concept_NameName of the concept in the FHIR structure.stringrequired : 1
Computer_Ready_NameA Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this.string-
TypeThe type the structure describes.string-
Dollar_RefThe "$ref" string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON value being referenced.string-
DescriptionA free text natural language description of the structure and its use.string-
ItemsThe value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value.string-
RequiredThe value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value.string-
ConstThe value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword.string-

MedicationRequestresourceTypeThis is a MedicationRequest resourceMedicationRequest
MedicationRequestid#/definitions/idThe logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
MedicationRequestmeta#/definitions/MetaThe metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
MedicationRequestimplicitRules#/definitions/uriA reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
MedicationRequest_implicitRules#/definitions/ElementExtensions for implicitRules
MedicationRequestlanguage#/definitions/codeThe base language in which the resource is written.
MedicationRequest_language#/definitions/ElementExtensions for language
MedicationRequesttext#/definitions/NarrativeA human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
MedicationRequestcontainedarrayThese resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.{'$ref': '#/definitions/ResourceList'}
MedicationRequestextensionarrayMay be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.{'$ref': '#/definitions/Extension'}
