12.19 Resource DeviceRequest - Content

Orders and Observations

Work Group

Maturity Level: 1

Trial Use

Security Category: Patient

Compartments: Device, Encounter, Patient, Practitioner

Represents a request for a patient to employ a medical device. The device may be an implantable device, or an external assistive device, such as a walker.

12.19.1 Scope and Usage

Trial-Use Note: In terms of scope and usage, the Orders and Observations workgroups wish to draw the attention of reviewers and implementers to the following issue:

We are seeking input from the implementation community on whether to combine DeviceRequest and VisionPrescription for R4. The parameters element was added to DeviceRequest for representing custom details for ordering devices. With this change, VisionPrescription significantly overlaps DeviceRequest. To illustrate this, the devicerequest-left-lens and devicerequest-right-lens examples are based on the general glasses example in VisionPrescription.

This resource is a request resource from a FHIR workflow perspective - see Workflow.

This resource describes the request for the 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 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.

The device use request may represent an order or a prescription entered by a practitioner in a CPOE system or a proposal made by a clinical decision support (CDS) system based on a patient's clinical record and context of care.

12.19.2 Boundaries and Relationships

This resource deals with the allocation of a device to a patient and while it may contain instructions on how to use the device, the data about getting the device to the patient is addressed in other resources. For example, certain devices must be implanted via a surgical or other procedure and the implantation or explantation is represented in the [Procedure](procedure.html) or [ServiceRequest](servicerequest.html) resource.

The SupplyRequest resource is similar in that it deals with requesting a particular item for a specific patient. However, DeviceRequest is concerned with items where there is a patient focus, or instructions regarding their use, whereas SupplyRequest is concerned with inventory management.

12.19.3 References

This resource is referenced by CarePlan, Claim and Observation.

This resource implements the Request pattern.
