Prevalence of and Characteristics Associated With Overbasalization Among Patients With Type 2 Diabetes Using Basal Insulin: A Cross-Sectional Study.

This article describes a cross-sectional analysis of 655 patients to determine the prevalence of and patient-specific characteristics associated with overbasalization in patients with type 2 diabetes. Overbasalization was defined as uncontrolled A1C (>8%) plus a basal insulin dose >0.5 units/kg/day. The period prevalence of overbasalization was found to be 38.1, 42.7, and 42% for those with an A1C >8, ≥9, and ≥10%, respectively. Those with an A1C ≥9% had the greatest likelihood of experiencing overbasalization. These results suggest that overbasalization may play a role in patients not achieving optimal glycemic control in type 2 diabetes.
