This research study is being conducted to gather information about patients with inflammatory bowel disease (IBD) to better understand their knowledge and preferences about self-help resources and learn how to help patients better manage their disease. Participation in this study will involve signing a research consent form, completing questionnaires, and the opportunity to participate in self-help resources. Some participants may be offered the opportunity to participate in a virtual focus group, as well. Participation in the study will last approximately 3 months.

This is a prospective, multicenter, observational study in an international setting (North America, Europe, and Israel) to follow clinical outcomes for patients with complex fistulizing conditions for 24 months after undergoing surgical intervention to treat the index fistula. During participation, standardized data on exposure and outcomes (clinical, patient reported outcomes (PROs), and Healthcare Resource Utilization (HCRU)) will be collected from electronic data capture forms (EDCs). Following the surgical intervention for the fistulizing condition (index date), outcomes will be assessed at 3 months, 6 months, 12 months, and 24 months post-surgery (post-index).
