  • Agenda Check
  • Minutes from
  • Agenda
    • review and propose actual wording for Device elements ( also a Device QA task to review comments and descriptions ) especially in light of the changes from udi to udiCarrier.
*8926 Provide Clearer guidance for UDI components (Eric Haas) Persuasive
  • Intro:


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 includes 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.

determine whether harvested stuff gos here or in new resource

  • Scope


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.

use this instead:

This resource an administrative resource that tracks individual device types or instances of a device and their location. It Is referenced by other resource for recording which device performed an action such as a procedure or an observation. It is also referenced when prescribing and dispensing devices for patient use or for ordering supplies.

  • Boundaries and Relationships

change first part to:

    • 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

(consider adding reference to the IEEE Model)

(rest ok)

NOTE: Determine whether harvested stuff gos here or in new resource and determine boundaries.

  • Device Identifier

Chamge to:

Definitions: Unique instance identifiers assigned to a device by manufacturers other organizations or owners.

Comments: The barcode string from a barcode present on a device label or package may identify the instance, include names given to the device in local usage, or may identify the type of device. If the identifier identifies the type of device, Device.type element should be used. If the barcode is the 'unique device identifier' (UDI), The FHIR Device.Identifier element corresponds to the variable portion of a UDI that identifies the serial number of a specific device. See <UDI mappings> for a complete mapping of UDI parts to Device.

  • Device.udiCarrier

Change to:

Definition: Unique device identifier (UDI) barcode or rfid string assigned to device label or package. - see http://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/UniqueDeviceIdentification/default.htm.

(note use markup for the reference)

Comment: The udiCarrier string may identify an unique instance of a device, or it may only identify the type of the device. The Human Readable format (HRF) is strongly preferred over the AIDC form which may contain non-displayable control characters( this issue still up for debate ). See <UDI mappings> for a complete mapping of UDI parts to Device.

( moves this to devices notes as general discussion or point to a reference.)

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 ( moves this to devices notes as general discussion or point to a reference.)

  • Device.type

Definition: Code or identifier to identify a kind of device. (no change)

NOTEL make tracker on GMDN as binding since have to pay for it. swithc to 49062001 Device (physical object)Hierarchy

stopped here plan to finish and create local build to share with WG for comment and vote

  • AOB (Any Other Business)
