The study aimed to explore the impact of CGM on the frequency of diabetic ketoacidosis events in Medicare patients with type 2 diabetes on prandial insulin.
Analyzed 100% CMS FFS Parts A, B, and D data from 2018-2022.
Identified patients with type 2 diabetes on prandial insulin using ICD-10 codes; exclusions applied to those with type 1 diabetes, gestational diabetes, or age <65.
Utilized mixed-effects, zero-inflated negative binomial regression to estimate DKA rates, adjusting for various comorbidities.
Before CGM implementation, 1,241 patients (1.6%) experienced ≥1 DKA event compared to 586 patients (0.7%) after CGM initiation (p<0.001).
Adjusted incidence rate ratio (IRR) of DKA events post-CGM was 0.85 (95% CI 0.73-0.99), indicating a significant reduction.
