Predictors of Unplanned Health Care Utilization Among Children with Inflammatory Bowel Disease in a Rural Region of the Southeastern US.

Abstract

Background: Pediatric Inflammatory Bowel Disease (IBD) imposes significant healthcare costs and strains emergency services. This study aimed to identify factors associated with unplanned healthcare usage among children with IBD in a rural, medically underserved region in the southeastern United States.

Methods: In this retrospective cohort study, we analyzed children (<18 years) with moderate or severe IBD followed at an academic pediatric gastroenterology clinic between 2016 and 2021. Each planned visit was treated as a separate observation, and patients were followed after each planned visit until the occurrence of the earliest unplanned healthcare event, until the next planned visit, or until censoring.

Results: In our analysis of 471 planned visits from 70 children with IBD, we observed 84 (18%) unplanned visits within 12 months, with 39 of these visits related to IBD. Unplanned visits occurred at a median interval of 39 days, predominantly to the emergency department (ED). Multivariate Cox proportional hazards analysis revealed a higher hazard of unplanned visits among female patients, individuals with elevated C-reactive protein levels and anemia, those covered by Medicaid insurance, and those residing closer to the clinic.

Conclusions: This study elucidates the challenges faced by children with IBD in rural settings. By identifying factors associated with unplanned healthcare utilization, we can better pinpoint patients who may benefit from targeted interventions to reduce such visits.
