BACKGROUND AIMS: We examined treatment patterns and clinical outcomes in a contemporary cohort of children with newly diagnosed inflammatory bowel disease (IBD) in a large, commercially insured U.S. population.
METHODS: Using the OptumLabs® Data Warehouse, we created an inception cohort of physician-diagnosed IBD in children aged 6-17 years between 2007-23. We examined cumulative incidence of hospitalization, surgery, safety events, and medication use in patients with Crohn's disease (CD) and ulcerative colitis (UC), overall and stratified by diagnostic era, race and ethnicity, sex, and age at diagnosis.
RESULTS: Among 787 children with newly diagnosed CD (age at diagnosis, 13.4±2.9y; 57% male; 82% White, 5% Black, 7% Hispanic) followed over mean 4.6±3.0y, 5-year risk of IBD-related hospitalization and major surgery was 30% and 10%, respectively. In children diagnosed in 2019-23, 1-year cumulative use of corticosteroids and advanced therapy was 46% and 75%, respectively; advanced therapy use increased significantly over time (aHR, 3.43 [95% CI, 2.71-4.32] for 2019-23 vs. 2007-12), while corticosteroid use declined (0.67 [0.53-0.84]). Risk of IBD-related hospitalization was lower in children diagnosed between 2019-23 (0.65 [0.43-0.97]) compared with those diagnosed between 2007-12; surgical risk did not decline significantly, with confidence intervals compatible with a clinically meaningful reduction. Among 399 children with newly diagnosed UC (age at diagnosis, 14.0±3.0y; 53% male; 78% White, 5% Black, 7% Hispanic) followed over 4.5±3.0y, 5-year risk of IBD-related hospitalization and colectomy was 36% and 8%, respectively. Advanced therapy use increased significantly over time (4.46 [2.85-6.98] for 2019-23 vs. 2007-12), with no significant change in hospitalization or surgical risk across eras. No consistent racial and ethnic, age, or sex differences in advanced therapy use or clinical outcomes were identified in either CD or UC.
CONCLUSIONS: In a contemporary cohort of commercially insured children with newly diagnosed IBD, early advanced therapy use has increased markedly over time. Surgical risk did not decline significantly in either disease; however, the study was not powered to exclude a clinically meaningful reduction, and these findings are hypothesis-generating rather than conclusive.
