In Patients With Inflammatory Bowel Disease, Racial Disparities Exist in Burden of Vaccine-preventable Disease Hospitalizations and Outcomes.

ABSTRACT

OBJECTIVE: Patients with inflammatory bowel disease (IBD) are at increased risk of vaccine-preventable diseases (VPDs). Despite the increasing prevalence of IBD in non-white populations, little is known regarding racial disparities in VPD burden. METHODS: Retrospectively analyzing the 2016 to 2020 National Inpatient Sample, we identified adults with IBD hospitalized for a principal diagnosis of VPD. The primary outcome investigated was hospitalization for VPD stratified by patient-reported race. Secondary outcomes were in-hospital morbidity, mortality, length of stay, and health care utilization. Multivariable regression analysis was performed to adjust for patient and hospital characteristics. RESULTS: The search identified 554,114 hospitalizations for VPD, including 4170 hospitalizations in patients with IBD. Patients with IBD had significantly greater odds of hospitalization from herpes zoster virus (adjusted odds ratio [aOR] 1.73) and varicella zoster virus (aOR 2.31). Comparing white and non-white patients with IBD, significant racial disparities were noted. Non-white patients were at greater odds of hospitalization from influenza (aOR 1.74), herpes zoster virus (aOR 1.77), and varicella zoster virus (aOR 1.62). In-hospital morbidity was greater in non-white patients, including greater odds of requiring intensive care unit stay (aOR 1.18). Morbidity was elevated in African Americans, with greater odds of acute kidney injury (aOR 1.25), venous thromboembolism (aOR 1.17), respiratory failure (aOR 1.16), and intensive care unit stay (aOR 1.18). No differences were found in mortality, length of stay, and health care utilization. CONCLUSIONS: Significant racial disparities in VPD hospitalization and in-hospital morbidity were found among adults with IBD in the United States. With the increasing prevalence of IBD in non-white populations, targeted efforts are needed to improve health equity.
