A Randomized Controlled Trial of Opt-in Versus Opt-Out Colorectal Cancer Screening Outreach

摘要

OBJECTIVES: Colorectal cancer (CRC) screening uptake is suboptimal, despite national efforts to increase screening rates. Behavioral economic approaches such as changing defaults may increase participation. We compare response rates to opt-in or opt-out messaging in mailed fecal immunochemical test (FIT) outreach.
