Evaluation of Novel Trend Arrow Adjustment Tool for Diabetes Patients Using Continuous Glucose Monitoring to Guide Insulin Bolus Adjustment (TAAT Study)

The Trend Arrow Adjustment Tool formula is: if CGM shows a single arrow up or down: adjust bolus by +/- (1.5/ISF) and for 2 arrows up or down +/- (3/ISF). Where ISF is the patients own insulin sensitivity factor.

The 10/20% bolus adjustment formula is: if CGM shows a single arrow up or down: adjust bolus by +/- 10% and for 2 arrows up or down +/- 20%.
