Summary

Colorectal cancer is the second deadliest cancer in the US and hits underresourced communities hardest. This trial compared two mail-based outreach approaches to boost screening in community health centers, including among English- and Spanish-speaking patients. At 90 days, overall screening participation was low, but the more advanced test including phone, text, and email reminders had greater participation than the test with only text reminders. Follow-up colonoscopy rates were poor. The findings demonstrate that test choice and outreach strategies must fit local context to support successful screening.
