Reduced Systemic Corticosteroid Use among Pediatric Patients With Inflammatory Bowel Disease in a Large Learning Health System.

Objectives: Corticosteroids have long been used to treat inflammatory bowel disease. However, cumulative corticosteroid exposure is associated with adverse effects, particularly in growing children. Professional guidelines recommend steroid-sparing strategies. It remains unknown whether corticosteroid use has decreased in children with inflammatory bowel disease.

Methods: We performed retrospective cohort study using data from 2007 to 2018 from the international multi-center ImproveCareNow Network, a pediatric inflammatory bowel disease quality improvement collaborative. Pediatric patients diagnosed with inflammatory bowel disease were included. Patients with missing diagnosis or corticosteroid use data were excluded. We performed serial cross-sectional analyses of period prevalence and used multivariate regression models.

Results: 27,321 patients were included (65% Crohn disease, 28% ulcerative colitis, 7% indeterminate colitis). Corticosteroids were used in 10,206 (37%). Corticosteroid use decreased from 28% (2007) to 12% (2018). Black patients received corticosteroids more commonly than white patients. This disparity improved as corticosteroid use decreased in both groups. Most corticosteroid use occurred <120 days after diagnosis. Corticosteroid or 5-aminosalicylate use <120 days after diagnosis predicted later corticosteroid use. Anti-tumor necrosis factor-alpha medication use <120 days after diagnosis was associated with a reduction in corticosteroid use. As corticosteroid use decreased, steroid-sparing therapy use increased and height and weight z scores improved, particularly among children with Crohn disease. Despite improvement across the network, variation in corticosteroid usage remains.

Conclusions: Corticosteroid use among pediatric patients with inflammatory bowel disease in the ImproveCareNow Network has decreased over time. Racial disparities in corticosteroid use were found, but gradually improved.
