Effect of Mailed Invites of Choice of Colonoscopy or FIT vs. Mailed FIT Alone on Colorectal Cancer Screening

This is a pragmatic, randomized, controlled trial comparing whether a mailed outreach intervention offering patients who are not up-to-date with colorectal cancer (CRC) a choice of completing a home Fecal Immunochemical Test (FIT) test or scheduling a screening colonoscopy increases CRC screening completion compared to a mailed FIT kit outreach program (which does not offer an explicit choice of screening modality). The trial will be conducted in a racially and socioeconomically diverse cohort of patients served by an integrated safety net delivery system that has a "FIT first" population health screening strategy. All patients will also have access to whatever CRC screening is recommended through usual visit-based care.
