Profile of Device for decision support/quality metrics. Defines the core set of elements and extensions for quality rule and measure authors. 

**Usage**
FHIR defines the [Device Resource](http://hl7.org/fhir/R4/device.html) as 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. FHIR and US Core further differentiate devices into two “classes”: 
* Devices that interact with the human body but do not stay in it are referred to as non-implantable medical devices.
* Implantable devices are those which stay in the human body with a medical objective for an extended period of time, or even a lifetime.

Accessed 28 January 2020.] 
 

The FHIR Device Resource addresses both implantable and non-implantable devices. US Core only references Implantable Device. US Quality Core uses Implantable Device from US Core. Separately, builds directly from FHIR to address non-implantable devices with US Quality Core profiles as the device resource.

Therefore, when creating an expression for an eCQM or a CDS artifact, assure you are using the appropriate Device or Implantable Device resource.
