Xu et al reported factors affecting the length of stay (LOS) and readmission rate for patients with diabetic ketoacidosis. This can help to identify patients who may benefit from more aggressive management. The authors are from the Cleveland Clinic and Case Western Reserve University.

Patient selection: hospital admission for diabetic ketoacidosis


Predictors of a prolonged length of stay:

(1) ICU admission (odds ratio 2.1), an indicator of severe disease

(2) longer disease duration (nonlinear, odds ratio 1.3)

(3) non-white race (odds race 1.7)

(4) older age at admission (odds race 1.03)

(5) Elixhauser index (odds ratio 1.2), as a measure of comorbidity


Predictors of shorter LOS:

(1) shorter time to consult after admission


Predictors of readmission:

(1) Medicare insurance (odds ratio 2.4), which may be an indication of older age

(2) Elixhauser index (odds ratio 1.3)

(3) older age at admission (nonlinear odds ratio 1.05)


Predictors of lower readmission:

(1) endocrinologist consultation (odds ratio 0.5)
