Abstract

INTRODUCTION: Clinical inertia and the complexity of basal insulin titration are major barriers to optimal glycemic control in adults with type 2 diabetes (T2D). A prototype of the Dexcom Smart Basal system known as basal therapy optimization (BTO), a continuous glucose monitoring (CGM)-informed basal insulin optimization system, was evaluated for its efficacy, safety, and impact on patient-report…
