Summary
Brief summary (as posted)
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.

- Group 1 - Automated Mailing
- description
- The mailing process will be identical to those used in the SOS study. Mailing 1 includes an introductory letter on CRC screening and a pamphlet on CRC testing choices (colonoscopy every 10 years, FIT testing yearly, or flexible sigmoidoscopy every 10 years combined with interval FIT testing), and pros and cons of each. The letter will state that they will soon be receiving a FIT kit in the mail, and a number to call if they prefer another option. Mailing 2 includes a brief letter reaffirming the importance of screening, a FIT kit (the one used by Group Health), pictograph instructions, and a postage-paid return envelope. Mailing 3 a reminder letter, is sent to participants not completing the FIT kit after 3 weeks. The intervention for Group 1 includes no incentive.
