This resource records the use of a healthcare-related device by the patient, a provider or a related person, and is primarily used for patient-reported or second-hand reporting. The resource can be used to note the use of an assistive device such as a wheelchair or hearing aid, a contraceptive, or an implanted device such as a pacemaker. It may also be used, for example, to capture an approximate assertion that the patient used the device over a six month period.

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

Boundaries and Relationships

There are several resources that can be used to represent device use events or requests. The following Resources should be used in the following manner:

DeviceRequest - records a request to use the device.

Procedure- records the implant or explant event of a device in a patient.

DeviceAssociation - If precise information (e.g., from the assigning system) about the association of the device with the patient is known, DeviceAssociation is the typical mechanism to record the information.
