Nudge study aims to boost colon cancer screening in 20,000 patients
NCT ID NCT05693649
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether sending patients direct reminders and giving their doctors electronic nudges can increase colorectal cancer screening rates. About 20,000 adults aged 50-72 who are overdue for screening will be randomly assigned to receive different types of outreach or usual care. The goal is to see which approach gets more people screened over three years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Behavioral interventions (direct patient outreach, clinician nudges, text reminders)
- What this could lead to
- If successful, this could show that simple outreach and reminders significantly increase colorectal cancer screening rates in primary care.
- What could go wrong
- This is a behavioral study, not a drug trial, so results depend on patient and clinician engagement. It may not work in other healthcare settings or populations.
