Devices (external | implantable), such as insulin infusion pump, implantable cardioverter-defibrillator, need to be programmed to operate correctly based on patient's clinical status. For example:
Insulin infusion pump dosage - basal and bolus dosage
Implantable cardioverter-defibrillator (ICD) - pacing mode
These device function parameters may also need to be adjusted from time to time, based on changing patient clinical status
The initial setting and subsequent parameters adjustments need to be captured for reasons including: decision traceability, evaluation of parameter setting clinical effectiveness, to inform future device function parameter setting, etc

A detail analysis of the FHIR Device (and Device related) resources lead to the assessment that these requirements are not supported by the current Device resource structure.
This change request is to suggest a detail review of the requirements and to determine the optimal change decision(s).
An analysis document is uploaded to provide more detail use cases analysis and contextual information to support this change request.
