Introduction and Objective: While continuous glucose monitoring (CGM) can enhance diabetes (DM) management, its impact on outpatient, high-cost complications is understudied, particularly in community health centers (CHCs).Methods: Using electronic health record data from a national CHC network, we examined demographic characteristics, care utilization (number of visits and telehealth use), CGM use, and outpatient acute DM complications (e.g. infections, cardiovascular disease, DM complications). Patients with Type 2 Diabetes (T2D) over the age of 18 years and seen between 1/2020 and 8/2023 were included. We used logistic regression to evaluate the association between CGM use and having one or more outpatient acute DM complication, controlling for sex, race, ethnicity, age, last A1c, telehealth use, and total visits during the study period.Results: Among 130,148 patients with T2D (mean age 50.2±12.6 years), 56% were female, 49% Hispanic, 48% White, 21% Black, and 6% other or multiple races (Table 1). Few were prescribed CGM (2.6%). Overall, 54% had HbA1c ≥7% (mean 7.9±2.1%) and a large proportion (58%) utilized telehealth. CGM use was associated with lower odds of having one or more outpatient acute complication compared with no CGM use (OR 0.75, [95% CI 0.69, 0.82], p<0.001).Conclusion: CGM use in CHCs is low. Even so, CGM use is associated with lower odds of outpatient complications. Expanding access may help mitigate complication rates.
