Causes and predictors for 30-day re-admissions in adult patients with diabetic ketoacidosis in the United States: A nationwide analysis, 2010-2014

Abstract

Objective: We aimed to determine the causes and predictors for 30-day re-admission following a hospitalization for diabetic ketoacidosis (DKA) in the United States. Methods: This retrospective cohort study analyzed data from the National Re-admission Database. We included adult patients with a primary discharge diagnosis of DKA, from 2010 to 2014. Our primary objective was to determine the frequency and causes for 30-day re-admission after an index hospitalization for DKA. We also performed multivariate regression analyses using covari-ates from the index admission to identify predictors for 30-day re-admissions. Results: Among 479,590 admissions for DKA, 58,961 (12.3%) were re-admitted within 30 days. Recurrent DKA represented 40.8% of all-cause re-admissions. In multivariate analysis, end-stage renal disease (odds ratio [OR], 2.13; 95% confidence interval [CI], 2.00 to 2.27; P
