DKA hospital admission trend study published
Hospital admission trends for diabetic ketoacidosis (DKA) for both type 1 and type 2 diabetes in England have been examined as part of a cohort study.
In the previous two decades the number of adults being admitted to hospital with DKA has increased and associated healthcare performance did not improve, except decreased length of hospital stay.
The study involved 23,246 adults with type 1 diabetes and 241,441 adults with type 2 diabetes from the Clinical Practice Research Datalink and Hospital Episode Statistics.
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 one-year all-cause mortality rates were determined using joinpoint regression, negative binomial regression, and logistic regression models.
For type 1 diabetes, the incidence of hospital admission for DKA increased between 1998 and 2007 and remained static until 2013. The incidence in 2013 was higher than that in 1998 (incidence rate ratio 1.53 [95% CI 1.09–2.16]).
For type 2 diabetes, the incidence increased 4.24% (2.82–5.69) annually between 1998 and 2013. The length of hospital stay decreased over time for both diabetes types (P ≤ 0.0004).
Adults with type 1 were more likely to be discharged within two days compared with adults with type 2 diabetes (odds ratio [OR] 1.28 [1.07–1.53]). The 30-day readmission rate was higher in type 1 diabetes than in type 2 diabetes (OR 1.61 [1.04–2.50]) but remained unchanged for both diabetes types over time. Trends in 30-day and one-year all-cause mortality rates were also stable, with no difference by diabetes type.
