INTRODUCTION: Treatment options for patients with moderate-severe ulcerative colitis (UC) are increasing. The appropriateness of their use in mild-moderate UC is less clear, as is the role of surgical intervention. Our aim was to define the appropriateness of therapeutic options in a range of clinical scenarios in mild-moderate UC METHODS: We applied the RAND/UCLA Appropriateness Method to rate appropriateness of treatment choices in patients with mild-moderate UC; severe disease (likely to need hospitalization or surgery within 2 weeks) was excluded. A literature review was presented to the BRIDGe group, a panel of 13 IBD specialists, as well as 1 external IBD expert and 2 IBD surgical experts. 12 chapters were constructed including failed 5-ASA, steroid or thiopurine therapy, and primary/secondary non-response to biologics or tofacitinib. Scenarios were also divided by disease extent (proctitis vs more extensive) and activity (mild vs moderate) creating 260 scenarios in all. Panellists used a modified Delphi method to anonymously rate the appropriateness of a therapy on a 1-9 scale (1-3 not appropriate, 4-6 uncertain, 7-9 appropriate). Disagreement was assessed using a validated index (DI) and was defined as a DI > 1. The panellists then convened in person to discuss areas of disagreement, followed by a second round of rating. Scenarios rated a median of 7 or higher were deemed appropriate and those rated 3 or lower were deemed inappropriate. Scenarios rated 4-6 were considered uncertain, as were any with a DI > 1 RESULTS: Appropriateness was agreed in 131 and inappropriateness in 47 scenarios. Greatest disagreement was around the use of thiopurines, but no scenario had a DI > 1. There were 82 scenarios were rated uncertain. Biologics and tofacitinib were more likely to be rated appropriate for treatment resistance and greater disease activity; disease extent less likely to influence decision making. Surgery was felt to be appropriate in 8 scenarios, generally in more extensive and active disease that had failed to respond to medical therapy. Surgery was felt to be inappropriate in 16 scenarios and was uncertain in 24 CONCLUSION: Although there was little disagreement amongst an expert panel of IBD physicians and surgeons, there remained uncertainty about the use of medical and surgical therapy in nearly one third of situations in patients with mild-moderate UC. These results could be used to guide the design of clinical trials for these patient groups in order to guide best practice.

Abstract Background & Aims Crohn’s disease (CD) is a lifelong illness with substantial morbidity, although new therapies and treatment paradigms have been developed. We provide guidance for treatment of ambulatory patients with mild to severe active luminal CD. Methods We performed a systematic review to identify published studies of the management of CD. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a group of specialists. Results The consensus includes 41 statements focused on 6 main drug classes: antibiotics, 5-aminosalicylate, corticosteroids, immunosuppressants, biologic therapies, and other therapies. The group suggested against the use of antibiotics or 5-aminosalicylate as induction or maintenance therapies. Corticosteroid therapies (including budesonide) can be used as induction, but not maintenance therapies. Among immunosuppressants, thiopurines should not be used for induction, but can be used for maintenance therapy for selected low-risk patients. Parenteral methotrexate was proposed for induction and maintenance therapy in patients with corticosteroid-dependent CD. Biologic agents, including tumor necrosis factor antagonists, vedolizumab, and ustekinumab, were recommended for patients failed by conventional induction therapies and as maintenance therapy. The consensus group was unable to clearly define the role of concomitant immunosuppressant therapies in initiation of treatment with a biologic agent. Conclusions Optimal management of CD requires careful patient assessment, acknowledgement of patient preferences, evidence-based use of existing therapies, and thorough assessment to define treatment success.
