8.14 Resource Device - Content

Orders and Observations Work Group Maturity Level : 2   Trial Use Security Category : Business Compartments : Not linked to any defined compartments

A type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.

8.14.1 Scope and Usage

This resource is an administrative resource that tracks individual instances of a device and their location. It is referenced by other resources for recording which device performed an action such as a procedure or an observation, referenced when prescribing and dispensing devices for patient use or for ordering supplies, and used to record and transmit Unique Device Identifier (UDI) information about a device such as a patient's implant.

8.14.2 Boundaries and Relationships

These are the device related resources

  • Device (this resource)
  • DeviceDefinition - Describes a "kind" of device - not a physical instance, cut a "catalog entry" where a device is defined by the manufacturer, reseller, or regulator.
  • DeviceMetric - Describes a measurement, calculation or setting capability of a medical device.

In FHIR, the "Device" is the "administrative" resource for the device (it does not change much and has manufacturer information etc.), whereas the DeviceComponent and DeviceMetric (which is really a kind of DeviceComponent) model the physical part, including operation status and is much more volatile. The physical composition of a Device is represented by the Devices pointing to their "parent".

Devices differ from medications because they are not "used up" - they remain active in a patient in an ongoing fashion. However, the specific boundary between medications and devices is defined at the implementation level and this standard does not enforce a boundary with the exception of devices that are implanted in a patient. The Medication resource should not be used to represent implanted devices.

8.14.3 References

This resource is referenced by Signature , Account , AdverseEvent , Appointment , AppointmentResponse , AuditEvent , CarePlan , CatalogEntry , ChargeItem , ChargeItemDefinition , Claim , ClinicalUseDefinition , Communication , CommunicationRequest , Composition , Consent , Contract , DetectedIssue , itself, DeviceMetric , DeviceRequest , DeviceUseStatement , DiagnosticReport , DocumentManifest , DocumentReference , EvidenceReport , EvidenceVariable , ExplanationOfBenefit , Flag , Group , GuidanceResponse , ImagingStudy , Invoice , List , MeasureReport , Media , MedicationAdministration , MedicationDispense , MedicationRequest , MessageHeader , MolecularSequence , Observation , Procedure , Provenance , QuestionnaireResponse , RequestGroup , RiskAssessment , Schedule , ServiceRequest , Specimen , SupplyDelivery , SupplyRequest and Task .

8.14.3.2 8.14.4.2 Notes

8.14.3.2.1 8.14.4.2.1 Device Identifier and Device Type

Nearly all devices are assigned a string of characters to represent one or more identifiers or codes, which are usually printed or affixed to the device using either barcodes or RFIDs. The identifier or code can come from the manufacturer (for example, a 'serial number', 'reference number', or 'catalog number'), various institution and registries. Any of these identifiers or codes assigned to the device can and should be recorded in the device resource. However, there can there can be confusion where to represent them in the resource because codes and identifiers are represented in FHIR as semantically distinct elements and because organizations may conflate the term 'code' for an identifier or 'identifier' for a code in their names.

The identifier element is only intended for use when it's an actual identifier for a specific instance of a device. That would mean that each device would have a separate serial number and would be represented using this element - devices without serial numbers (for example, a box of syringes) would not. Concepts such as a reference number or catalog number or GTIN describe a code which represents a kind of device and are conveyed using the type element. Some sources of standard codes for devices and translations within type are listed below:

8.14.3.2.2 8.14.4.2.2 Unique Device Identifier (UDI)

The International Medical Device Regulators Forum IMDRF UDI Working Group published UDI System for Medical Devices (Version 2.0) , the base specification for Unique Device Identifiers (UDI). The United States Food and Drug Administration has produced an implementation guide for Unique Device Identifiers (UDI) which implements the IMDRF specification and other jurisdictions may produce similar IMDRF implementation guides as well. The full UDI string that represents the barcode as printed on the packaging of the device or Automatic Identification and Data Capture (AIDC) representation is called the "UDI carrier". The UDI has 2 components*:

  • Device identifier (DI)**, which is the actual identification component
  • Production identifier(s)(PI) which provide the means to track a device through its manufacture, distribution and use.

*non-UDI elements may also appear within the UDI carrier. **a "GTIN" (sometimes also called an EAN number) is a code developed by GS1 for the kind of device not an identifier for the device. A GTIN may appear on its own or it may appear in a UDI string as the DI component.

The DI of the UDI may be stored in a jurisdictional repository and used as the primary key to access other device information. For example, in the United States, the DI of the UDI is submitted in a device record to the Global Unique Device Identification Database (GUDID) . The UDI may identify an instance of a device uniquely (when the PI includes a serial number), or it may just identify the type of the device. The UDI is parsed into its constituent parts (DI, PI and other elements) by parsing rules developed by each Issuing Agency standard. Where the device has an assigned UDI, the other details carried in the resource (e.g., lot, expiration date, etc.) SHALL be consistent with the information encoded in the UDI string or registered in the local repository.

Best practice guidelines for transmitting UDI data using the Device resource dictate transmitting both the UDI Carrier and all components found within the UDI as described in Device UDI Mapping . Several examples are provided for further guidance.
