Financial incentives didn't improve response rates to mailed colorectal cancer screening tests

(JAMA Network) Financial incentives didn't increase completion rates of colorectal cancer screening tests mailed to patients. In a randomized clinical trial of almost 900 patients, none of the incentives (an unconditional $10, a promised $10 upon completion of the fecal immunochemical test (FIT) kit to test for blood in a stool sample or chance at a lottery with a 1-in-10 chance of winning $100) was statistically better than no financial incentive to entice patients to complete the FIT.
