## Resource Profile: QICore DeviceRequest 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/us/qicore/StructureDefinition/qicore-devicerequest | *Version*:7.0.2 | |
| * Standards status: *[Trial-use](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 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](index.md#mustsupport-flag).

**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

**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](StructureDefinition-qicore-devicerequested.md); to specifically request information that a DeviceRequest intentionally did not occur for a medical, patient or system reason, use the profile [QICoreDeviceProhibited](StructureDefinition-qicore-deviceprohibited.md).

  See the [patterns](patterns.md) page for implementation and usage patterns.
