Healthcare Utilization and Geographic Distribution of Advanced Therapy in Minority Race and Ethnic Groups With Inflammatory Bowel Disease.

Abstract

Background and aims: Biases in healthcare pose challenges for inflammatory bowel disease (IBD) patients from underrepresented races and ethnicities. Our study aimed to assess the quality of and access to care among underrepresented racial and ethnic populations using a diverse database.

Methods: We used the OneFlorida Data Trust, representing over half of Florida's population. We performed a retrospective study from 2012 to 2020. Advanced IBD therapies included a prescription of at least 1 biologic agent or tofacitinib. Disease activity markers included C-reactive protein (CRP), hemoglobin (Hgb), albumin, and white blood cell (WBC). Regression analyses compared the rates of medication use, healthcare utilization, and disease severity by race and ethnicity. Geographic distribution of advanced IBD therapy was analyzed at the county level.

Results: Our study included 10 578 patients. Hispanic patients utilized more biologics than non-Hispanic White (NHW) patients (odds ratio [OR]: 1.3, P < .0001). Non-Hispanic Black patients utilized more steroids than NHW (OR: 1.2, P = .0004). Hispanics had fewer visits to emergency departments (EDs) and fewer admissions compared with NHW (OR: 0.7 and 0.6, respectively; P < .0001). Non-Hispanic Black patients visited ED more frequently than NHW patients (OR: 1.3, P < .0001). Hispanics had lower disease activity markers than NHW based on CRP (OR: 0.5, P = .005), Hgb (OR: 0.4, P < .0001), albumin (OR: 0.7, P < .0001), and WBC (OR: 0.5, P < .0001). Geographic distribution of advanced IBD therapy showed clustered areas in southern and northern Florida.

Conclusions: Our data show an improved access to care pattern in Hispanic patients. However, disparities still exist, and this is evident in the healthcare utilization trends observed among non-Hispanic Black patients.
