Assessing the efficacy of a hybrid closed loop system in a racial-ethnic minority cohort of children and adolescents with type 1 diabetes.

Objectives: Despite improved outcomes in the use of a hybrid closed loop system (HCLS), significant disparities in the application of this technology exist among youth with type 1 diabetes (T1DM). The study aimed to evaluate the impact of a tubeless HCLS on glycemic outcomes in a pediatric racial-ethnic minority population.

Methods: A retrospective, single-center study included youth with T1D initiating HCLS Omnipod 5. Outcomes included HbA1c, continuous glucose monitor variables, BMI Z score, and episodes of diabetic ketoacidosis (DKA). Outcomes were compared from baseline, 3 and 6 months of Omnipod 5 start.

Results: The study included 174 participants, aged between 2 and 22 years, with a mean age of 7.9 ± 3.7 years. Hispanics constituted 87.3 % (152) of the cohort, with 53 % males and 47 % females. Insurance coverage was 56.9 % public, 42.5 % private, and 0.5 % uninsured. Baseline HbA1c level was 8.0 % ± 1.7, 7.3 % ± 1.1 at 3 months and 7.3 % ± 1.1 at 6 months (p<0.001). Glucose time in range (TIR) was 54.5 % at baseline to 61.9 % at 3 months, and 60.5 % at 6 months (p<0.001). Notably, there were no changes in BMI z-scores or DKA episodes following the initiation of the HCLS Omnipod 5.

Conclusions: The study showed that a tubeless HCLS significantly improved glycemic control in a pediatric minority cohort with T1DM, without affecting BMI Z-scores or increasing DKA episodes. Ongoing efforts to address disparities in diabetes technology access are crucial for optimizing care and alleviating the burden on individuals with T1DM across racial backgrounds.
