Intelligent therapy recommendation algorithm and method of using the same
First Claim
1. 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, wherein the predefined threshold value is 0.05 or 0.1 U/h when the stored pump parameter is a basal rate, the predefined threshold value is 5 grams carbohydrates per unit of insulin when the stored pump parameter is a carbohydrate-to-insulin ratio (CR), and the predefined threshold value is 5 mg/dl for a Unit of insulin when the stored pump parameter is an insulin sensitivity factor (ISF);
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.

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.

15. 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, wherein the predefined threshold value is 0.05 or 0.1 U/h; 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 (16, 17, 18)
