Colonoscopy Versus Stool-based Testing for Older Adults With a History of Colon Polyps
This is a multi-site comparative effectiveness randomized controlled trial (RCT) comparing annual fecal immunochemical testing (FIT) and colonoscopy for post-polypectomy surveillance among adults aged 65-82 with a history of colorectal polyps who are due for surveillance colonoscopy.
Inclusion: English or Spanish speaking; Personal history of colorectal polyps; Most recent colonoscopy with ≤2 non-advanced polyps; Currently due or coming due within 12 months for colonoscopy; Able to provide written informed consent.
