Device

Device represents an instrument, apparatus, implement, machine, contrivance, implant, in-vitro reagent, or other similar or related article, including a component part or accessory, intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease and not dependent on being metabolized to achieve any of its primary intended purposes.

Documented evidence of a device may exist in a clinical record in various ways:

• A provider may document placement of a device as an intervention or procedure (e.g., the QDM datatypes "Intervention, Performed", or "Procedure, Performed"). Example: ["Procedure, Performed": "Pacemaker insertion"].
• The provider may document presence of the device as a finding, perhaps including the finding on the problem list. Example: ["Diagnosis": "Pacemaker present"], or ["Assessment, Performed": "Pacemaker present"].
• A provider may also document the device as an observation or "Assessment, Performed".
  • Example: ["Device, Applied": "Transtelephonic monitoring of pacemaker assessment"].

Given the variation in determining evidence of device usage, a measure developer may need to include multiple queries (or retrieves) to assure capture of all devices present in the measure population. The QDM 5.6 retires datatype "Device, Applied" with recommendation to use "Procedure, Performed", "Intervention, Performed", "Diagnosis", or "Assessment, Performed" as noted above.
