Scaling CRC Screening Through Outreach, Referral, and Engagement (SCORE)

This study will test the effectiveness of mailing fecal immunochemical tests (FITs) in increasing colorectal cancer (CRC) screening rates in U.S. adults ages 45-75. We are implementing this study in two age groups, 45-49 years and 50-75 years.

Trial (Age Group 50-75) This randomized controlled trial assesses the effectiveness, feasibility, acceptability, and cost-effectiveness of mailing FITs from a central location to patients served by FQHCs. Subjects are randomly selected and assigned to receive either a mailed FIT intervention (Arm 1: Trial Mailed FIT Intervention - Age Group 50-75) or usual care (Arm 2: Trial Usual Care - Age Group 50-75). To assess United States Preventive Services Task Force recommendations for annual screening, we will mail subjects one round of FIT per year for up to two years. Sub-study (Age Group 45-49) A sub-study assesses the effectiveness of mailing FITs from a central location to patients who are 45-49 years of age and newly eligible for CRC screening. The sub-study also assesses the impact of varying the appearance of the FIT packet mailing envelope on FIT return. All eligible patients from one FQHC clinic site are randomly assigned to receive either a mailed FIT intervention that includes an enhanced mailing envelope (Arm 3: Sub-study Mailed FIT Intervention Enhanced Envelope - Age Group 45-49) or a plain envelope (Arm 4: Sub-study Mailed FIT Active Comparator Plain Envelope - Age Group 45-49). The Trial (Age Group 50-75) and the Sub-study (Age Group 45-49) also assess the effectiveness of delivering patient navigation from a central location to facilitate follow up colonoscopy for patients with a positive (abnormal) FIT result.
