(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)
