355-OR: Glycemic Outcomes with CGM Use in Patients with Type 2 Diabetes—Real-World Analysis

Introduction & Objectives: While the benefits of CGM use in T1D are well documented, its efficacy across the spectrum of T2D patients in real-world settings has not been evaluated. We assessed the effects of CGM use in a large T2D adult population across the treatment spectrum, considering non-insulin therapies (NIT), basal insulin (BIT), and prandial insulin (PIT) with/without non-insulin medications. Methods: This retrospective,12-month analysis used data from a large claims database that included >7.1 million patients with T2D in the electronic medical records. The two observation periods were: pre-index period -- 360 days prior to patients' first CGM claim; and post-index period -- 360 days after to the first CGM claim. The index date (baseline) was the date of the first CGM claim between December 27, 2019, and January 5, 2022. The primary outcome was change in HbA1c closest to 12 months after CGM acquisition. Results: The analysis included 16,410 adults with T2D (NIT, n=4,659; (BIT, n=6,182, and PIT, n=5,569) with mean baseline HbA1c 8.8% and mean age 59 years. At 12 months, the mean change in HbA1c was significant in all three subgroups compared with HbA1c levels in the pre-index period. (Figure) Conclusions: In this 12-month, real-world study, CGM use was associated with significant improvements in glucose control in both non-insulin and insulin-treated patients with T2D.
