Colorectal cancer (CRC) is the third leading cause of cancer death in the US. Early detection improves CRC outcomes and multiple options are endorsed for CRC screening; however, adherence remains challenging. Among Medicaid enrollees, the fecal immunochemical test (FIT) is often used for average-risk CRC screening, with suboptimal adherence rates reported (12.3–23.2 %). The navigation-supported (personalized outreach by phone, mail, email and text), at home collection, multi-target stool DNA (mt-sDNA) test represents a relatively recent and broadly accessible option for average-risk CRC screening in Medicaid enrollees. We assessed cross-sectional mt-sDNA adherence in a national sample of Medicaid patients. Data from Exact Sciences Laboratories LLC (ESL; Madison, WI) were retrospectively analyzed. Participants included individuals 45 + years covered by Fee-For-Service (FFS)- or Managed-Medicaid. Primary analysis focused on the 50–74 age cohort and included those with valid mt-sDNA orders between January 1–December 31, 2018. Data from 25,794 individuals who received valid orders for mt-sDNA were included in analysis (61.2 % women; mean age at order 57.5 years). Overall adherence – completion of an ordered test – was 51.3 %. Adherence was 54.6 % in Managed-Medicaid and 38.9 % in FFS-Medicaid. Adherence by age was: 51.5 % for 50–64 years and 47.7 % for 65–74 years. Mt-sDNA tests ordered by gastroenterologists had higher adherence (60.5 %) compared with primary care clinicians (51.3 %). These data from a large, national sample of Medicaid-insured patients substantiate mt-sDNA testing as a viable patient-supported, home-based option to improve average-risk CRC screening participation in Medicaid enrollees.
