1627-P: Real-World Comparison of Acute Complications in Adult Patients with Type 1 Diabetes in U.S. and European Registries

The study compares acute complications among adults with type 1 diabetes (T1D) by glycemic control in a U.S. Electronic Health Record database (T1PCO) with the German/Austrian Prospective Diabetes Follow-up (DPV). T1PCO included 31,430 and DPV 5,190 individuals in the analysis (age ≥18 years, T1D duration ≥2 years). During baseline (12 months prior to index date), ≥1 HbA1c and ≥1 insulin prescription was required. Baseline demographics, severe hypoglycemia (SH) and diabetic ketoacidosis (DKA) were analyzed for overall populations, by age group, and glycemic control (HbA1c categories). In both databases, incidence of DKA was highest in those with HbA1c ≥9.0%. Additionally, the incidence of DKA (per year) increased with deteriorating control (HbA1c
