Relationships of race and area deprivation indices to outcomes in pediatric patients with inflammatory bowel disease

Objectives: Social determinants of health (SDOH) are nonmedical factors that influence health outcomes. Children with chronic illnesses living with socioeconomic risk factors have higher rates of unfavorable health outcomes. Our study aimed to assess the association between area deprivation indices (ADI), as a proxy for SDOH, and outcomes in pediatric patients with inflammatory bowel disease (IBD). Methods: A retrospective chart review was conducted on 134 pediatric patients with IBD, ages 0-21 years. Explanatory variables were the patient's ADI and demographics. Outcomes were assessed from time of diagnosis over a 1-year follow-up period. The primary outcome was the ratio of missed to completed appointments; secondary outcomes were the numbers of IBD-related emergency department (ED) visits and IBD-related hospitalizations. Results: Race/ethnicity was significantly associated with ADI (p < 0.001). In a multivariable regression model, no variables were associated with ratio of missed to completed appointments. Notably, ADI was not significantly associated with the ratio of missed to completed appointments. In a Poisson regression, Black (non-Hispanic) and Hispanic race/ethnicity, Medicaid insurance, female gender, and lower age were significantly associated with more IBD-related ED visits; ADI was not. In a similar model, Black (non-Hispanic) race, Medicaid insurance status, and lower age were significantly associated with more IBD-related hospitalizations; ADI was not. Conclusions: In our cohort, ADI was not significantly associated with the ratio of missed to completed appointments, IBD-related ED visits, and IBD-related hospitalizations; however, race/ethnicity, age at diagnosis, insurance, and gender were associated with these outcomes.
