Hospital admissions: who is admitted through the emergency department?

This study examines the co-variates that separate patients who presented an emergent condition without a physician referral and were admitted through the hospital emergency department (ED) from their counterparts who were referred by a physician for the treatment of an elective or urgent condition and were admitted through the admissions department. The analysis was based on 295,945 inpatient admissions in 1999 to short-term acute-care hospitals in Oklahoma. Employing hospital admission as the unit of analysis, logistic regression was used to examine the differential likelihood of admission without a physician referral and through the ED of the uninsured, Medicare beneficiaries, Medicaid recipients, African Americans and Native Americans. The results of the logistic regression analysis indicated that Medicaid recipients and the uninsured were more likely than their commercially-insured counterparts to be admitted, without a physician referral, to an acute-care hospital in Oklahoma following an evaluation in the ED. The findings also suggest that African Americans and, to a lesser extent, Native Americans were more likely than their white counterparts to be admitted through the ED without benefit of a physician referral.
