Mailed Outreach for Colorectal Cancer Screening in Community Health Centers: The CARES Pragmatic Cluster Randomized Clinical Trial

Listen to this summary

The authors aimed to compare the effectiveness of two mailed outreach strategies—fecal immunochemical test (FIT) with automated text messaging versus FIT-DNA with manufacturer outreach—in increasing colorectal cancer (CRC) screening rates among eligible adults in community health centers. The study found that the FIT-DNA group had significantly higher screening participation at both 90 and 180 days compared to the FIT group, with notable differences in uptake between locations. Despite these improvements, the follow-up colonoscopy completion rate after abnormal test results remained low.
