Financial Incentives to Increase Colorectal Cancer Screening in Priority Populations

The investigators propose to build on the success of the Systems of Support to Increase Colorectal Cancer trial (SOS, R01CA121125, Green) and focus on disparity groups who are less likely to be current for colorectal cancer (CRC) screening. We will test whether financial incentives increases screening uptake and decreases screening disparities. The investigators hypothesize that CRC screening rates will be higher in patients offered mailed fecal kits and financial incentives than those offered mailed fecal kits alone.

About this study

Study staff will send invitation letters and a questionnaire to 5,000 patients aged 50-75 not current for CRC screening, two-thirds who are identified in the electronic data as being from a non-White race, ethnicity, or who have Medicaid coverage. Those returning the survey and remaining eligible (estimated N = 1150) will be randomized to either (1) Mailed fecal kit only, or mailed fecal kit plus one of 2 types of financial incentives for completing testing: (2) a guaranteed Monetary incentive or (3) a probabilistic Lottery incentive.

Treatment and study plan

Auto Mailing Plus Money

Behavioral

Participant receives money as a thank you for completing CRC screening within 6 months.

Auto Mailing Plus Lottery

Behavioral

Participant has a 1 in 10 chance of winning money in a lottery for completing CRC screening within 6 months.

Primary outcomes

  1. CRC Screening Within 6 Months Following Randomization

    Time frame: 6 months

    We will compare among the 3 arms (1) automated mailing; (2) Auto mailing plus $10; (3) Auto mailing plus $50 lottery for completion and the effect of each on CRC screening completion at 6 months (yes/no) within the following subgroups of each arm: 1. White and not Hispanic versus non-White or Hispanic. 2. Medicaid versus non-Medicaid (Medicare, employer-based, private) insurance. 3. History of prior versus no prior completion of CRC screening tests. 4. High school or less versus college or more education level.
