Adjusted model includes age, gender, race, body mass index*, surgery service, admission glucose*, admission creatinine*, hospital length of stay*, basal insulin, heart failure, cardiovascular service, statin, aspirin, ACE/ARB and hypoglycemia (< 70 mg/dL within 24 h, < 70 during entire hospitalization, or < 40 mg/dL during entire hospitalization. * log transformed values
