5.5 Resource Device - Content

This resource identifies an instance of a manufactured thing that is used in the provision of healthcare without being substantially changed through that activity. The device may be a machine, an insert, a computer, an application, etc. This includes durable (reusable) medical equipment as well as disposable equipment used for diagnostic, treatment, and research for healthcare and public health.

5.5.1 Scope and Usage

This resource is primarily used for recording which device performed an action and can also be used to track device location. It is also used for prescribing and dispensing devices for patient use. If the device is implanted in a patient, then the patient element will be present, and there would be no location.

Devices that are implanted in a patient differ from medications because they are not "used up" - they remain active in a patient in an ongoing fashion. The Medication resource SHOULD not be used to represent implanted devices.

5.5.2 Boundaries and Relationships

There are two device related resources

The device capabilities and log resources are used when communicating with a device, either directly or indirectly. When a channel is opened with the device, or its proxy, it first sends the Capabilities resource, and then a series of log resources. The FHIR JSON format is used in this case.

The application that receives the log resources may choose to merge the log with the capabilities statement to create a device observation, which is suitable for wider use within a EHR/Clinical record context.

5.5.3 Resource Content

Device (Resource)Identifiers assigned to this device by various organizations. The most likely organizations to assign identifiers are the manufacturer and the owner, though regulatory agencies may also assign an identifier. The identifiers identify the particular device, not the kind of deviceidentifier : Identifier 0..*A kind of this devicetype : CodeableConcept 1..1 <<Defines the nature of the device and the kind of functionality/services/behavior that may be expected from itDeviceKind>>A name of the manufacturermanufacturer : string 0..1The "model" - an identifier assigned by the manufacturer to identify the product by its type.

5.5.3.2 Notes

5.5.3.3 Device Identifiers

Nearly all devices are assigned one or more identifiers, which are usually printed or affixed to the device using either barcodes or RFIDs. The identifiers can come from the manufacturer (often called the "serial number", various institution and registries. Any of these identifiers assigned to the device can and should be recorded in the device resource. The different identifiers are differentiated by their use, label, and system values.

The most important of the identifiers is the Unique Device Identifier (UDI), which most medical devices are required to carry and which can be used to access the Global Unique Device Identification Database (GUDID). The UDI has its own element (udi). The UDI may identify an instance of a device uniquely, or it may just identify the type of the device. A portion of the UDI - the DI part - can be extracted from the UDI when required, and used to look up information about the device through the GUDID. Where the device has an assigned UDI, the other details carried in the resource (e.g. lot, expiry date etc) SHALL be consistent with the information encoded in the UDI or registered in the GUDID.

Note that a GTIN (sometimes also called an EAN number) is a code for the kind of device, not an identifier for the device. The GTIN may be part of the UDI, but it may also be known separately, in which case GTINs should be carried in the type element:

GTIN example

  <type>
    <coding>
      <system value="urn:oid:1.3.160‎"/>
      <value value="00614141999996"/>
    </coding>
    <!-- other codes for type -->
  </type>
