METHODS TO DEMONSTRATE PROGRESS TOWARDS FULL ADAPTATION AND TO PRESENT POTENTIAL IMPROVEMENTS THROUGH BEHAVIORAL CHANGES
Exemplary embodiments calculate a user's progress towards maximum adapted system performance when utilizing a drug delivery device such as an insulin pump and display this progress to the user. Further embodiments calculate potential changes to a particular user's interaction with the system given a history of glucose and insulin deliveries and provide guidance to that user. This can be used, for example, to change how the user splits up their basal and bolus doses to improve metrics such as time-in-range, incidences of hyper- or hypo-glycemia, time in hyper- or hypo-glycemia, mean glucose, etc. It may also be used to speed the above-described adaptation process by suggesting changes that the user can make to achieve stability more quickly.
