Insights
Children with Crohn's disease (CD) and perianal fistulizing complications (PFCs) use significantly more antibiotics. This highlights the need for better antibiotic stewardship and evidence-based treatment strategies in pediatric CD management.
Area of Science:
- Pediatric Gastroenterology
- Inflammatory Bowel Disease Research
- Pharmacology and Therapeutics
Background:
- Crohn's disease (CD) is a chronic inflammatory bowel disease affecting children.
- Perianal fistulizing complications (PFCs) are a common and challenging manifestation in pediatric CD.
- Antibiotic use is frequent in managing pediatric CD, but patterns and associations with complications require characterization.
Purpose of the Study:
- To investigate antibiotic utilization patterns in children diagnosed with Crohn's disease (CD).
- To determine the association between antibiotic dispensing and the development of perianal fistulizing complications (PFCs) in pediatric CD patients.
- To analyze predictors of antibiotic use in this specific patient population.
Main Methods:
- Retrospective analysis of US administrative claims data from 2009-2018.
- Inclusion of patients aged 21 years or younger with CD and 5 years of continuous enrollment.
- Evaluation of patient demographics, medication dispensing records, and disease outcomes using multivariable regression models.
Main Results:
- A cohort of 5,277 pediatric CD patients was analyzed; 17% developed PFCs.
- Antibiotic prescriptions were common, with 83% of patients receiving at least one.
- Patients with PFCs exhibited significantly higher antibiotic dispensing (median 67 days) compared to those without PFCs (median 27 days), a 90% increase in adjusted analysis.
Conclusions:
- Perianal fistulizing complications (PFCs) are prevalent in pediatric Crohn's disease and strongly linked to increased antibiotic use.
- A substantial proportion of pediatric CD patients with PFCs receive extensive antibiotic prescriptions.
- The findings underscore the critical need for evidence-based treatment guidelines and robust antibiotic stewardship programs for pediatric CD.
Objective:
To characterize patterns of antibiotic use among children with Crohn's disease and perianal fistulizing complications (PFCs) via a large, national administrative database.
Study Design:
Retrospective analysis of US administrative claims including patients ≤21 years with Crohn's disease diagnosed 2009-2018 and 5-years of continuous enrollment. We evaluated patient characteristics, medication dispensing, and disease outcomes. Multivariable negative binomial regression evaluated predictors of days of antibiotics dispensed.
Results:
Five thousand two hundred seventy-seven patients were included, with median age 16.0 years at diagnosis (55% male, 77% commercial insurance, 61% White). In total 17% developed PFC during enrollment. Antibiotic dispensing was common, 83% had at least 1 antibiotic prescription. Patients with PFC had more antibiotic days (median 67 days, IQR 26-138) compared with those without PFC (median 27 days, IQR 10-63; P = .001). In an adjusted model, patients with PFC had 90% more antibiotic dispensing than those without PFC.
Conclusions:
PFCs are common and are associated with greatly increased antibiotic dispensing with 1 in 12 patients filling >20 prescriptions during the 4-year study period. The optimal use of antibiotics remains unclear, and their extensive use in this population emphasizes the need for evidence-based treatment strategies and approaches to antibiotic stewardship.
