Could a phone call help rural americans beat colon cancer?
NCT ID NCT05453630
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study tests whether a remotely-delivered patient navigation program helps more rural adults complete colonoscopy screening for colorectal cancer. Participants aged 45-75 who are due for a colonoscopy receive either navigation support from a trained lay navigator or an educational brochure. The navigator helps schedule the procedure, addresses barriers, and provides coaching. The goal is to see if this approach increases screening rates in underserved rural populations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Patient navigation program (behavioral intervention)
- What this could lead to
- If effective, this program could increase colonoscopy completion rates in rural areas, reducing colorectal cancer deaths through earlier detection.
- What could go wrong
- The trial is relatively small and focuses on a specific population, so results may not apply broadly. Navigation programs also depend on community resources and may not be sustainable long-term.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Aged 45-76.25 on the date of their referral for colonoscopy * Referred for colonoscopy as part of colorectal cancer screening in the last 3 months. This includes patients referred for colonoscopy after an abnormal stool screening test (e.g., FIT/FOBT/Cologuard) and patients referred for colonoscopy as a primary screening test for colorectal cancer. Exclusion Criteria: * Deceased * Colonoscopy procedure since colonoscopy referral * Colonoscopy procedure scheduled less than or equal to 7 days from study enrollment date * Colonoscopy procedure scheduled more than 9 months from colonoscopy referral date (if known at enrollment) * Have diagnosis or past history of total colectomy or colorectal cancer (malignant neoplasm) at any time * Has hospice * Aged 66 and older living long-term in an institution for more than 90 consecutive days during the year prior to the query
