System and method to manage diabetes based on glucose median, glucose variability, and hypoglycemic risk
First Claim
1. A system for determining insulin titration using glucose central tendency and variability to avoid hyperglycemia, the system comprising:
- a nonvolatile memory in which is stored a plurality of glucose data representative of the sensed glucose of a patient over a period of time, the stored glucose data including glucose data from sensed glucose prior to a first insulin titration, glucose data from sensed glucose after the first insulin titration, and glucose data from sensed glucose after a subsequent insulin titration;
a display configured to visually present data;
a processor connected with the nonvolatile memory and the display, the processor programmed to retrieve stored glucose data from the nonvolatile memory, compare glucose data after the first insulin titration to glucose data after the subsequent insulin titration and determine an estimate of insulin titration sensitivity therefrom, and programmed to determine a new insulin titration amount based on the estimate of insulin titration sensitivity, the processor further programmed to control the display to present the new insulin titration amount.

Abstract
A system and method provides a glucose report for determining glycemic risk based on an ambulatory glucose profile of glucose data over a time period, a glucose control assessment based on median and variability of glucose, and indicators of high glucose variability. Time of day periods are shown at which glucose levels can be seen. A median glucose goal and a low glucose line provide coupled with glucose variability provide a view into effects that raising or lowering the median goal would have. Likelihood of low glucose, median glucose compared to goal, and variability of glucose below median provide probabilities based on glucose data. Patterns can be seen and provide guidance for treatment.
