## Resource Profile: QICore DeviceRequest

Official URL: http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-devicerequest | Version: 8.0.0-ballot
Standards status: Trial-use Active as of 2019-07-11 | Maturity Level: 4 | Computable Name: QICoreDeviceRequest

Profile of DeviceRequest for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors.

"Must Have", "QI Elements" and "primary code path" are defined in the QI-Core Must Support section.
QI Elements:

- status: (QI) draft | active | on-hold | revoked | completed | entered-in-error | unknown
- modifierExtension(doNotPerform): (QI) Extension
- authoredOn: (QI) When recorded
- intent: (QI) proposal | plan | directive | order | original-order | reflex-order | filler-order | instance-order | option
- code[x]: (QI) Device requested
- code[x].extension(codeOptions): (QI) Url of a value set of candidate devices
- subject: (QI) Focus of request
- identifier: (QI) External Request identifier

Primary code path: code
(PCPath) This element is the primary code path for this resource CQL Retrieve
Usage

The FHIR R4 and the QI-Core DeviceRequest profile describes the request to use of a device by a patient. The device may be any pertinent device specified in the Device resource. Examples of devices that may be requested include a wheelchair, hearing aids, or an insulin pump. The request may lead to the dispensing of the device to the patient or for use by the patient. Orders or recommendations for use of a device for a patient use the ServiceRequest resource.

The following example illustrates the use of DeviceRequest:

    define "Device Indicating Frailty":
      [DeviceRequest: "Frailty Device"] FrailtyDeviceOrder
        where FrailtyDeviceOrder.status in { 'active', 'on-hold', 'completed' }
          and FrailtyDeviceOrder.intent in { 'order', 'original-order', 'reflex-order', 'filler-order', 'instance-order' }
          and FrailtyDeviceOrder.doNotPerform is not true

The DeviceRequest profile defines the conformance expectations for a DeviceRequest, regardless of whether it is a positive or negative statement. The DeviceRequested and DeviceProhibited profiles derive from DeviceRequest and represent the positive and negative statements for a device request.

To create an expression indicating existence of a request for a device use the profile QICoreDeviceRequested; to specifically request information that a DeviceRequest intentionally did not occur for a medical, patient or system reason, use the profile QICoreDeviceProhibited.

See the patterns page for implementation and usage patterns.
