Disparities in Emergency Department Waiting Times for Acute Gastrointestinal Bleeding: Results From the National Hospital Ambulatory Medical Care Survey, 2009-2018.

Objective: The primary aim of this study was to assess waiting time (WT) across different racial groups to determine whether racial disparities exist in patients presenting with gastrointestinal bleeding (GIB) to the United States emergency departments (EDs).

Methods: Using the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2009 to 2018, we compared WT of patients with GIB across different racial/ethnic groups, including nonhispanic white (NHW), African American (AA), Hispanic White (HW), and Nonhispanic other. Multinomial logistic regression was applied to adjust the outcomes for possible confounders. We also assessed the trend of the WT over the study interval and compared the WT between the first (2009) and last year (2018) of the study interval.

Results: There were an estimated 7.8 million ED visits for GIB between 2009 and 2018. Mean WT ranged from 48 minutes in NHW to 68 minutes in AA. After adjusting for gender, age, geographic regions, payment type, type of GI bleeding, and triage status, multinomial logistic regression showed significantly higher waiting time for AA patients than NHW (OR 1.01, P =0.03). The overall trend showed a significant decrease in the mean WT ( P value<0.001). In 2009, AA waited 69 minutes longer than NHW ( P value<0.001), while in 2018, this gap was erased with no statistically significant difference ( P value=0.26).

Conclusion: Racial disparities among patients presenting with GIB are present in the United States EDs. African Americans waited longer for their first visits. Over time, ED wait time has decreased, leading to a decline in the observed racial disparity.
