Background: Adults with inflammatory bowel disease (IBD) have an increased risk of venous thrombotic events (TEs). We sought to evaluate the risk for TE in children and adolescents with IBD using a large population database.

Methods: The triennial Healthcare Cost and Utilization Project Kids’ Inpatient Database was used in a retrospective cohort study of hospitalized children in the United States across 1997, 2000, 2003, 2006, and 2009. Billing codes were used to identify discharges with Crohn disease, ulcerative colitis, pulmonary embolism, deep vein thrombosis, thrombophlebitis, thrombosis of intracranial venous sinus, Budd-Chiari syndrome, and portal vein thrombosis. A logistic regression model was fitted to quantify the increased risk of TE in children with IBD, while adjusting for other risk factors of thrombosis.

Results: The total weighted number of pediatric discharges was 7,448,292, and 68,394 (0.92%) were identified with IBD. The incidence of any TE in a hospitalized child or adolescent with IBD was 117.9/10,000 with a relative risk (95% confidence interval) of 2.36 (2.15–2.58). The adjusted odds ratio for any TE in a patient with IBD without surgery was 1.22 (1.08–1.36). Risk factors for TE among patients with IBD include older age, central venous catheter, parenteral nutrition, and an identified hypercoagulable condition. There is an increasing trend of TE in both the IBD and non-IBD patients.

Conclusions: Hospitalized children and adolescents with IBD are at increased risk for TE. Conservative methods of TE prevention including hydration, mobilization, or pneumatic devices should be considered in hospitalized patients with IBD.
