OBJECTIVE: This study determined trends in hospital admission for diabetic ketoacidosis (DKA) in adults with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) from 1998 to 2013 in England. RESEARCH DESIGN AND METHODS: The study population included 23,246 adults with T1DM and 241,441 adults with T2DM from the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES). All hospital admissions for DKA as the primary diagnosis from 1998 to 2013 were identified. Trends in hospital admission for DKA in incidence, length of hospital stay, 30-day all-cause readmission rate, and 30-day and 1-year all-cause mortality rates were determined using joinpoint regression, negative binomial regression, and logistic regression models. RESULTS: ≤ 0.0004). Adults with T1DM were more likely to be discharged within 2 days compared with adults with T2DM (odds ratio OR 1.28 1.07-1.53). The 30-day readmission rate was higher in T1DM than in T2DM (OR 1.61 1.04-2.50) but remained unchanged for both diabetes types over time. Trends in 30-day and 1-year all-cause mortality rates were also stable, with no difference by diabetes type. CONCLUSIONS: In the previous two decades in England, hospitalization for DKA increased in adults with T1DM and in those with T2DM, and associated health care performance did not improve except decreased length of hospital stay.
