Abstract
An algorithm and method of making intelligent therapy recommendations for insulin pump parameters is described. The pump parameters include basal rates, carbohydrate-to-insulin ratios (CIR), and insulin sensitivity factors (ISF). A determination of whether a therapy recommendation should be made is based on comparing an updated recommended change with a threshold. The updated recommended change to the pump parameter is made based on a previous recommended change to the pump parameter and the difference between a current blood glucose value and a targeted blood glucose level. The algorithm and method confirms the therapy recommendation is within safety parameters before displaying the therapy recommendation.

22. A method of automatically making a therapy recommendation to adjust a stored insulin pump parameter, the method comprising the steps of:
-
obtaining a blood glucose value at the end of a time interval; determining if an intervening event occurred during the time interval before the blood glucose value was obtained, wherein the intervening event includes at least one of a meal, a correction bolus, and an error code that changes the blood glucose value unrelated to the stored pump parameter and thereby interferes with recommending a change to the stored pump parameter; recommending no change to the stored pump parameter based on the blood glucose value if the intervening event occurred during the time interval before the blood glucose value was obtained; updating a recommended change to the stored pump parameter based on a previous recommended change to the stored pump parameter and the difference between the blood glucose value and a target blood glucose level if no intervening event occurred during the time interval; comparing an absolute value of the updated recommended change to a predefined threshold value of the stored pump parameter; making no therapy recommendation if the updated recommended change does not exceed the threshold or the therapy recommendation is not within safety parameters; making the therapy recommendation if the updated recommended change exceeds the threshold and the therapy recommendation is within safety parameters; and displaying the therapy recommendation to adjust the stored pump parameter. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method of automatically making a therapy recommendation for adjusting a basal rate stored on an insulin pump, the method comprising the steps of:
-
obtaining a blood glucose value at the end of a time interval; determining if an intervening event occurred during the time interval, wherein the intervening event changes the blood glucose value unrelated to the stored basal rate and thereby interferes with recommending a change to the stored basal rate; recommending no change to the stored basal rate based on the blood glucose value if the intervening event occurred during the time interval; updating a recommended change to the stored basal rate based on a previous day recommended change to the stored basal rate during that interval and the difference between the blood glucose value and a target blood glucose level if no intervening event occurred during the time interval; comparing an absolute value of the updated recommended change to a predefined threshold value of the stored basal rate; making no therapy recommendation if the updated recommended change does not exceed the threshold or the therapy recommendation is not within safety parameters; making the therapy recommendation if the updated recommended change exceeds the threshold and the therapy recommendation is within safety parameters; and displaying the therapy recommendation to adjust the stored basal rate. - View Dependent Claims (37, 38, 39)
