8.14 Resource Device - Content

Orders and Observations Work GroupMaturity Level: 2 Trial UseCompartments: Device

This resource identifies an instance or 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. Medical devices include durable (reusable) medical equipment, implantable devices, as well as disposable equipment used for diagnostic, treatment, and research for healthcare and public health. Non-medical devices may include items such as a machine, cellphone, computer, application, etc.

This resource is an administrative resource that tracks individual device types or 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 Identifer (UDI) information about a device such as a patient's implant.

These are the device related resources

  • Device (this resource)
  • DeviceMetric - Describes a measurement, calculation or setting capability of a medical device.
  • DeviceComponent that the DeviceMetric is part of. This can be a DeviceComponent of any kind like a VirtualMedicalDevice (VMD), a MedicalDeviceSystem (MDS) , or a Channel

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 DeviceComponents pointing to their "parent" component using DeviceComponent.parent, e.g. channel to VMD and VMD to the MDS. All components point to the "logical" Device they belong to, using DeviceComponent.source. If you want to represent the version ( e.g., a software version) as well as other attributes of the DeviceComponent, the DeviceComponent.productSpecification is used. When representing which logical device your observations came from, use Device. But if you need to be more specific, the Observation resource can point to DeviceMetric or DeviceComponent which in turn reference the "logical" Device they belongs to.

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.

This resource is referenced by Account, AdverseEvent, Appointment, AppointmentResponse, AuditEvent, CatalogEntry, ChargeItem, Claim, Communication, CommunicationRequest, Composition, Consent, Contract, DetectedIssue, DeviceComponent, DeviceMetric, DeviceRequest, DeviceUseStatement, DiagnosticReport, DocumentManifest, DocumentReference, ExplanationOfBenefit, Flag, Group, GuidanceResponse, ImagingManifest, List, Media, MedicationAdministration, MedicationDispense, MedicationRequest, MessageHeader, Observation, Procedure, ProcedureRequest, Provenance, QuestionnaireResponse, RequestGroup, RiskAssessment, Schedule, Sequence, Specimen, SupplyDelivery, SupplyRequest and Task

The example binding used for the device element is from SNOMED CT. However, there are many other sources of possible codes for device type including:

Note that there may be translations of type code using one or more of these and other vocabularies

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," "reference number," or "catalog 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 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 futher guidance.
