Importance: Emergency department (ED) boarding times have increased rapidly, but their health equity outcomes are unknown., Objective: To investigate whether prolonged ED boarding is associated with increased perceived racial discrimination and dissatisfaction and whether associations vary between patients from marginalized racial and ethnic groups vs non-Hispanic White patients., Design, Setting, and Participants: This is a cross-sectional study of hospitalized adults who boarded in the ED during internal medicine admissions at a large, urban hospital in Boston, Massachusetts, from June 2023 to January 2024. Equal proportions of non-Hispanic White patients and patients from marginalized racial and ethnic groups (American Indian or Alaska Native, Hispanic, non-Hispanic Black and/or African American, and multiracial) were selected randomly., Exposure: The duration of ED boarding was categorized as less than 4 hours (reference), 4 to less than 24 hours, and 24 or more hours., Main Outcomes and Measures: Primary outcomes were odds of reporting (1) discrimination via the Discrimination in Medical Settings scale, and (2) dissatisfaction via the adapted Picker Patient Experience-15 questionnaire. Marginalized race and ethnicity was tested as an effect modifier. Multivariable logistic regression models adjusted for patient age, sex, language, and insurance payer., Results: Of 598 patients approached, 527 were enrolled, and 525 completed the surveys (response rate, 87.8%). The mean age (SD) was 60.6 (18.7) years, 300 patients (57.1%) were female, 246 patients (47.3%) identified as non-Hispanic White, and 274 (52.7%) were from a marginalized racial or ethnic group. In total, 135 (25.7%) boarded less than 4 hours (reference), 202 (38.5%) boarded 4 to less than 24 hours, and 188 (35.8%) boarded 24 hours or longer. Compared with less than 4 hours, boarding 24 hours or longer was associated with increased perceived discrimination (odds ratio [OR], 1.84; 95% CI, 1.14-2.99; P = .01). An increased association was observed in the subgroup of patients from racial and ethnic marginalized groups (OR, 2.36; 95% CI, 1.20-4.65; P = .01); effect modification was not significant (P for interaction, .10). For all patients, boarding 24 hours or longer was associated with increased dissatisfaction with care (OR, 1.77; 95% CI, 1.03-3.06; P = .04); effect modification was not significant (P for interaction, .80)., Conclusions and Relevance: In this cross-sectional study, hospitalized patients who boarded in the ED 24 hours or longer reported more discrimination and dissatisfaction with care, which may disproportionately affect patients from marginalized racial and ethnic groups. As ED boarding times increase nationally, it is critical to recognize their potential to exacerbate health inequities and to respond with equity-focused solutions.
