Financial Incentives to Promote Colorectal Cancer Screening: A Longitudinal Randomized Control Trial. | LitMetric

AI Article Synopsis

Article Abstract

Background: Financial incentives may improve health behaviors. We tested the impact of offering financial incentives for mailed fecal immunochemical test (FIT) completion annually for 3 years.

Methods: Patients, ages 50 to 64 years, not up-to-date with screening were randomized to receive either a mailed FIT outreach ( = 6,565), outreach plus $5 ( = 1,000), or $10 ( = 1,000) incentive for completion. Patients who completed the test were reinvited using the same incentive the following year, for 3 years. In year 4, patients who returned the kit in all preceding 3 years were reinvited without incentives. Primary outcome was FIT completion among patients offered any incentive versus outreach alone each year. Secondary outcomes were FIT completion for groups offered $5 versus outreach alone, $10 versus outreach alone, and $5 versus $10.

Results: Year 1 FIT completion was 36.9% with incentives versus 36.2% outreach alone ( = 0.59) and was not statistically different for $10 (34.6%; = 0.31) or $5 (39.2%; = 0.070) versus outreach alone. Year 2 completion was 61.6% with incentives versus 60.8% outreach alone ( = 0.75) and not statistically different for $10 or $5 versus outreach alone. Year 3 completion was 79.4% with incentives versus 74.8% outreach alone ( = 0.080), and was higher for $10 (82.4%) versus outreach alone ( = 0.033), but not for $5 versus outreach alone. Completion was similar across conditions in year 4 (no incentives).

Conclusions: Offering small incentives did not increase FIT completion relative to standard outreach.

Impact: This was the first longitudinal study testing the impact of repeated financial incentives, and their withdrawal, on FIT completion.
