NCT ID NCT07220018
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 5 times
Summary
This study tests whether sending text messages can encourage homeless adults aged 45-75 to complete colorectal cancer screening. About 588 participants from shelter clinics in New York City will be randomly assigned to receive SMS reminders or standard care. The goal is to see if texting increases rates of colonoscopy or stool-based tests.
