When Perfect Is the Enemy of Good: Results of a RAND Appropriateness Panel on Treat to Target in Asymptomatic Inflammatory Bowel Disease.

BACKGROUND

A treat-to-target strategy for inflammatory bowel disease (IBD) recommends iterative treatment adjustments to achieve clinical and endoscopic remission. In asymptomatic patients with ongoing endoscopic activity, the risk/benefit balance of this approach is unclear, particularly with prior exposure to advanced therapies.

METHODS

Using the RAND/University of California Los Angeles Appropriateness Method, 9 IBD specialists rated appropriateness of changing therapy in 126 scenarios of asymptomatic patients with ulcerative colitis and Crohn's disease and active endoscopic disease. Disease extent and behavior, prior treatment, prior complications, and recent disease progression were considered, as were factors that might influence decision-making, including age and pregnancy. Ratings were collected through anonymous survey, discussed at an in-person meeting, and finalized in a second anonymous survey.

RESULTS

Panelists rated change in therapy as appropriate (i.e., expected benefit sufficiently outweighs potential harms from continuing therapy) in 96/126 scenarios, generally in patients with progressive, complicated, and/or extensive disease, while changing therapy was rated uncertain in 27 scenarios of mild and/or stable disease. Changing therapy was rated inappropriate in ulcerative colitis patients with mild and stable disease previously exposed to ≥3 therapies or with improved endoscopic activity, and in Crohn's disease patients with only scattered aphthous ulcers. The validated threshold for disagreement was not crossed for any scenario. Patient age older than 65 years and a plan for pregnancy in the next year might influence decision-making in some settings.

DISCUSSION

Appropriateness ratings can help guide clinical decision-making about changing therapy to achieve endoscopic remission in asymptomatic patients with IBD until data from ongoing randomized studies are available.
