Black patients experienced 9% higher odds of prolonged ED boarding compared to White patients, underscoring significant racial disparities.
Medicaid insurance increased the odds of prolonged boarding for marginalized racial and ethnic groups, particularly among Hispanic and Black patients.
Prolonged ED boarding occurred in over 32% of patients admitted, indicating a widespread issue in emergency healthcare access.
Health insurance access appears to mediate racial disparities in ED boarding times, demanding targeted interventions to address inequities.

Resumen

Rising emergency department (ED) boarding times have become a public health crisis. It is unclear whether certain racial and ethnic groups are disproportionately affected. To identify racial and ethnic inequities in ED boarding time and explore which factors may contribute to prolonged boarding times. Retrospective cohort study of 38,766 adults (≥18 years) admitted to internal medicine services from EDs at two Boston hospitals (March 2018-February 2024). Race and ethnicity categorized as non-Hispanic White (White), non-Hispanic Black (Black), Hispanic, and non-Hispanic "Other" (including Asian, American Indian/Alaska Native, Native Hawaiian/Pacific Islander, or unspecified). prolonged ED boarding (≥4 h from admission order to inpatient transfer). Multivariable logistic regression assessed associations; additional analyses evaluated health insurance as a mediator. Among 38,766 patients (53.1% female), 59.9% were White, 20.3% Black, 14.4% Hispanic, and 5.4% "Other" race and ethnicity. Prolonged ED boarding occurred in 32.1%. In adjusted models, Black patients had 9% higher odds (odds ratio OR, 1.09; 95% confidence interval CI, 1.03-1.15; p = .004) and "Other" racial and ethnic patients had 16% higher odds (OR, 1.16; 95% CI, 1.05-1.27; p = .003) compared to White patients of prolonged ED boarding; no significant difference was observed for Hispanic patients (OR, 0.98; 95% CI, 0.92-1.04; p = .51). Adjusting for insurance attenuated racial disparities in ED boarding. Medicaid insurance was consistently associated with increased odds of prolonged boarding across racial and ethnic groups, particularly among Hispanic (OR, 1.86; 95% CI, 1.63-2.12; p ≤ 0.001) and Black (OR, 1.78; 95% CI, 1.59-1.99; p < .001) patients. Medicare was associated with lower odds of prolonged boarding across all groups. Two-site study. Black and other marginalized racial and ethnic patients were more likely to experience prolonged ED boarding, and differential health insurance access may contribute to this inequity. As boarding rises nationally, targeted interventions are needed to reduce disparities.
