The DeviceDefinition is an adminsitrative resource that includes all relevant attributes to define the kind of device that can be referenced by multiple Devices to provide information that does not change for an instance.
The DeviceDefinition can also be used for catalogs or other use cases where the reference to a device is generically to a type of device, not a specific instance of a device. This may include procedures or observations where the specific device is not known or not relevant.
Example device definitions include specifications for an x-ray machine, implantable devices, lab analyzers, etc.
Note that with the acceptance of this proposal, the Device resource scope will be reduced to just the instance related attributes.
There does not appear to be a DeviceDefinition concept in the RIM, rather only the Device instance is referenced The Common Product Model touches on elements, but not all.
Separating the DeviceDefinition from Device enables more clear distinctions and use considering a number of use cases primarily focus on Device, while others focus on DeviceDefinition. Furthermore, there will be many more Device instances than there will be DeviceDefinition instances. The DeviceDefinition would be used in catalogs and go through independent updates from the Device instance.
Implementations of catalogs, e.g., LIVD as well as implementations needing to reference devices will all directly or indirectly use this device.
September 2018 inclusion in FHIR R4.
