Racial disparities in emergency department utilization among patients with newly diagnosed depression

Abstract

Objective: To test the hypothesis that racial and ethnic minorities have increased emergency department visit rates, despite being established with a primary care provider.

Methods: In this retrospective cohort study, ED visits without hospital admission in a 12-month period among patients with a new primary care provider-issued diagnosis of depression were assessed. Electronic medical record (EMR) data was obtained from 47 family medicine clinics in a large Michigan-based healthcare system. General linear regression models with Poisson distribution were used to predict frequency of ED visits.

Results: A total of 4159 patients were included in the analyses. In multivariable analyses, Black / African American race was associated with an additional 0.90 (95% CI 0.64, 1.16) ED visits and American Indian or Alaska Native race was associated with an additional 1.39 (95% CI 0.92, 1.87) ED visits compared to White or Caucasians (null value 0). These risks were only exceeded by patients who received a prescription for a typical antipsychotic drug agent.

Conclusion: Despite being established patients at primary care providers and having follow-up encounters, Black / African American and American Indian or Alaska Native patients with depression were considerably more likely to seek ED treatment compared to White/Caucasian patients with depression.
