Text reminders to boost colorectal cancer screening participation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pragmatic randomized trial tests whether a single SMS reminder can increase participation in a population-based colorectal cancer screening program using fecal immunochemical testing. Participants are adults 50–69 who have not completed screening five weeks after the initial invitation and are randomized 1:1 to receive an SMS reminder or continue with the standard postal reminder. The study leverages the Alhora secure messaging system and integrates with existing screening workflows in Vallès Occidental, with outcomes analyzed by intention-to-treat and per-protocol. A qualitative pilot informed the SMS content to ensure readability and cultural appropriateness. Results will inform whether mobile reminders can shorten response times and raise overall participation in screening efforts.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Women and men aged 50 to 69 years.
* Residents of the Vallès Occidental area.
* Individuals invited to the Colorectal Cancer Screening Program (PDPCCR) who have not participated within 5 weeks of the initial invitation.

Exclusion Criteria:

* Personal history of colorectal cancer.
* Inflammatory bowel disease (IBD)
* Colorectal polyps requiring specific clinical follow-up.
* Hereditary polyposis syndromes.
* High-risk family history of colorectal cancer: a first-degree relative diagnosed before age 50, or two or more first-degree relatives at any age.
* Severe morbidity that precludes the performance of a colonoscopy in the event of a positive test result.
