Racial and Ethnic Differences in Emergency Department Wait Times for Patients with Substance Use Disorder

Substance use-related morbidity and mortality rates are at an all-time high in the United States, yet there remains significant stigma and discrimination in emergency medicine about patients with this condition.

The purpose of this study was to determine whether there are racial and ethnic differences in emergency department (ED) wait times among patients with substance use disorder.

The study uses pooled data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2016 to 2018. The dependent variable is length of time the patient with a diagnosis of substance use disorder waited in the ED before being admitted for care. The independent variable is patient race and ethnicity. Adjusted analyses were conducted using a generalized linear model.

There were a total of 3995 reported ED events among patients reporting a substance use disorder in the NHAMCS sample between 2016 and 2018. After adjusting for covariates, Black patients with substance use disorder were significantly more likely to wait longer in the ED (35% longer) than White patients with substance use disorder (p < 0.01).

The findings showed that Black patients with substance use disorder are waiting 35% longer, on average, than White patients with the same condition. This is concerning, given that emergency medicine is a critical frontline of care, and often the only source of care, for these patients. Furthermore, longer wait times can increase the likelihood of leaving the ED without being seen. Programs and policies should address potential stigma and discrimination among providers, and EDs should consider adding people with lived experiences to the staff to serve as peer recovery specialists and bridge the gap for care.
