System and methods for analyzing blood glucose data and quantifying the success or failure of insulin therapy
First Claim
1. A computerized method of determining and reporting effectiveness of a blood glucose treatment therapy of multiple daily injections administered to a patient with diabetes which quantifies effectiveness as a success or failure of the administered blood glucose treatment therapy to reach glycemic goals based on blood glucose data collected from the patient via a biosensor, comprising:
- transmitting to a computing device via a wired and/or wireless connection blood glucose data collected from the patient via the biosensor;
averaging blood glucose level readings from the biosensor in the blood glucose data per day over a first period and thereby determining a first average testing frequency;
calculating a low blood glucose index (LBGI) with the computing device by;
using a logarithmic formula which transforms each collected blood glucose level from the blood glucose data to a symmetric scale which addresses scale skewing that diminishes significance of hypoglycemia indicated in the blood glucose data;
assigning a risk value to each transformed blood glucose level using a rule; and
averaging the assigned risk values and thereby determining the LBGI;
calculating a mean blood glucose level from the blood glucose data with the computing device;
calculating a standard deviation of the blood glucose data with the computing device;
determining with the computing device a failure of effectiveness of an administered blood glucose treatment therapy of the multiple daily injections administered to the patient with diabetes based upon;
determining with the computing device that the first average testing frequency exceeds a first testing frequency limit which governs sufficiency of the blood glucose data collected from the patient for use in quantifying the failure or success of the effectiveness of the administered blood glucose treatment therapy, anddetermining with the computing device that one or more of the following conditions have been met;
(i) the calculated LB GI exceeds a value for hypoglycemic risk,(ii) the calculated mean blood glucose level exceeds a limit for glycemic control, and(iii) the calculated standard deviation exceeds a limit for glycemic variability; and
reporting by the computing device via an input/output (I/O) device a recommendation to change from a blood glucose treatment therapy of the multiple daily injections to a continuous subcutaneous insulin infusion (CSII) therapy upon the failure of the effectiveness of the administered blood glucose treatment therapy from determining by the computing device that the first average testing frequency exceeds the first testing frequency limit and the one or more of the conditions (i)-(iii) were met.
