Automated Insulin Delivery Systems Reduce Acute Care Utilization Among People with Type 1 Diabetes

Strategic Insights -

A recent study evaluated the impact of automated insulin delivery (AID) systems compared to multiple daily insulin injections (MDI) on the odds and costs of acute care utilization among people with type 1 diabetes (PwT1D). The research, conducted from January 2019 to December 2021, analyzed electronic health record (EHR) data and administrative claims data. Findings showed that AID system users had lower odds of inpatient admission and emergency department visits, and incurred lower average costs compared to MDI users.

Key Takeaways:

  • The study included 7264 AID system users and 27,973 MDI users, with AID users being younger and having a higher proportion of females than MDI users.
  • After adjusting for pre-index characteristics, AID users had lower odds of inpatient admission (0.70 [95% confidence interval]: 0.63-0.77) and emergency department visit (0.76 [95% confidence interval]: 0.70-0.82) at 12 months.
  • AID system users incurred lower average 12-month costs for all-cause inpatient admission ($3054 vs. $4701; p-value not provided).
  • The study found that use of AID systems among PwT1D was associated with lower odds of inpatient and emergency department utilisation and lower costs in the follow-up period compared to MDI.
  • The research has been peer-reviewed and published in Diabetic Medicine in 2025.

Statistics:

  • 7264 AID system users included in the study
  • 27,973 MDI users included in the study
  • AID system users had a lower average 12-month cost for all-cause inpatient admission ($3054 vs. $4701)
  • Overall, AID system users had a 30-40% lower rate of inpatient admission and emergency department visits compared to MDI users
  • The study analyzed EHR data and administrative claims data from January 2019 to December 2021
