1971-P: Clinical Characteristics and Economic Burden of Diabetic Ketoacidosis in People with Type 1 Diabetes in the U.S.

Introduction and Objective: Diabetic ketoacidosis (DKA) is the most common acute complication of diabetes. In this study, we assessed the clinical characteristics and costs of DKA hospitalizations in people with type 1 diabetes (T1D). Methods: We searched the 2022 National Inpatient Sample database for people with T1D (E10. xx any position) and DKA hospitalizations using ICD-10 codes (E10. 1, E10. 10, E10. 11, principal diagnosis at discharge). We reported incidence, length of stay (LOS) using mean and standard deviation (SD), mortality using frequency (%), and hospitalization costs. Results: Among 382, 460 hospitalizations in patients with T1D, 34. 1% (n: 130, 465) had DKA as the principal diagnosis, corresponding to 341. 1 per 1, 000 T1D hospitalizations (Table). The average LOS was 3. 1 (4. 7) days. The inpatient mortality was 0. 3% (n: 385). The mean cost per hospitalization was 10, 140 (12, 350). Conclusion: This analysis provides recent national estimates of the incidence, LOS, mortality and cost of hospitalizations for DKA in people with T1D. One-third of hospitalizations in people with T1D in the U. S. were for DKA in 2022, with a total cost exceeding 1. 24 billion, highlighting a significant burden to patients and the health system.
