What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

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
