Abstract

Objectives: To determine if differences exist in hospital and intensive care unit (ICU)/operating room admission rates based on health insurance status. Methods: This was a retrospective, cross-sectional study of data from hospital clinical and financial records for all 2001 emergency department (ED) visits (80,209) to an academic urban hospital. Hospital admission and intensive care unit (ICU)/operating room admissions were analyzed, controlling for triage acuity, primary complaint, diagnosis, diagnosis-related group (DRG) severity, and demographics. Multivariate logistic regression models identified factors associated with hospital admission for underinsured (self-pay and Medicaid) compared with other insured (private health maintenance organization, preferred provider organization, worker's compensation, and Medicare) patients.

Results: Compared with the other insured group, underinsured patients were less likely, overall, to be admitted to the hospital (odds ratio [OR], 0.82; 95% CI

Keywords: admission, hospital, health insurance, intensive care unit, operating room
