Predicted time to assess and/or control a glycemic state

An article comprising:

• a non-transitory storage medium comprising machine-readable instructions stored thereon which are executable by a special purpose computing device to:
• define a plurality of different target blood glucose concentration levels for a patient;
• assign a plurality of different threshold time periods to the target blood glucose concentration levels, resulting in a plurality of different time-to-target checkpoints for the target blood glucose concentration levels, each of the plurality of different time-to-target checkpoints having a respective glucose control system operation associated therewith;
• observe a current blood glucose concentration for the patient based, at least in part, on signals received from a blood-glucose sensor;
• predict a respective duration of time for the patient's blood glucose concentration to reach each of the target blood glucose concentration levels using the observed current blood glucose concentration;
• identify which of the target blood glucose concentration levels is predicted to be reached first in time, based on the predicting;
• compare the predicted duration of time for the identified target blood glucose concentration level against the threshold time periods of the plurality of different time-to-target checkpoints of the identified target blood glucose concentration level, to determine an operation of the glucose control system based on the predicted duration of time and the plurality of different time-to-target checkpoints;
• and
• alter a therapy applied to the patient based on the determined operation of the glucose control system.
