Introduction and Objective: Automated insulin delivery (AID) systems improve glycemic outcomes for adults with type 1 diabetes (T1D), yet timely initiation following diagnosis remains suboptimal. We aimed to increase early AID initiation among newly diagnosed adults with T1D
Methods: Six adult centers from the T1D Exchange Quality Improvement Collaborative utilized quality improvement tools such as process maps, Ishikawa diagrams, effort impact matrices, and Plan-Do-Study-Act cycles to increase AID initiation among newly diagnosed adults with T1D. We describe a retrospective, multicenter descriptive analysis using aggregated data from 5 centers and compared trends from 2023-2025
Results: Across the 5 centers, 158, 106, and 104 adults were newly diagnosed with T1D in 2023, 2024, and 2025, respectively. Median time to AID initiation decreased from a range of 5-17.5 months in 2023 to 0-7 months in 2025. New-onset AID users who initiated AID within 6 months ranged from 14%-67% at baseline and increased to 50%-100% in 2025. Rates increased across all centers from year to year. Mean HbA1c decreased across all centers from pre-AID initiation to the end of calendar year following AID initiation
Conclusion: Multi-center QI initiatives are feasible and effective strategies in promoting timely initiation of automated insulin delivery following T1D diagnosis
