ABSTRACT
Overutilization of the emergency department (ED) is a significant problem in the United States (US), characterized mainly by patients with non-emergent conditions seeking care in a setting designed specifically for acute care. This has significantly increased healthcare costs in the US, a country with one of the most expensive healthcare systems in the world. ED overutilization was also found to be high among people with Medicaid coverage, especially since the Affordable Care Act was enacted with an expansion in Medicaid coverage. Using the 2018 South Eastern Pennsylvania (SEPA) Household Health Survey, we identified a significant bivariate relationship between emergency department visits and the following predictor variables: sex, race, education, employment status, 150% poverty level, and Medicaid recipient. Using a multivariable logistic regression model, Medicaid recipients had higher odds of presenting to the ED than non-Medicaid recipients [odds ratio (OR): 2.863, 95% confidence interval (CI): 2.164, 3.788]. Black people (OR: 1.647, 95% CI: 1.411, 1.923) and Native Americans (OR: 2.985, 95% CI: 1.536, 5.800) had higher odds than Whites. Respondents without a high school diploma had higher odds than college graduates (OR: 1.647, 95% CI: 1.96, 2.273). Respondents below the 150% poverty line had higher odds than those at or above the 150% poverty level (OR: 1.651, 95% CI: 1.386, 1.968). Unemployed respondents had higher odds than full-time employed respondents (OR: 1.703, 95% CI: 1.488, 1.953) or part-time (OR: 1.259, 95% CI: 1.036, 1.529). No difference was observed between the sexes. Addressing ED overutilization should take a multi-faceted approach with the ultimate goal of improving access to primary care.
