Swiss study tests if doctor training boosts colon cancer screening
NCT ID NCT03510858
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether training primary care doctors in shared decision-making could increase colorectal cancer screening rates. Doctors in quality circles received evidence summaries, decision aids, and stool test kits to help patients choose between colonoscopy and FIT. The study involved 44 doctors and measured how many patients got screened. The goal is to see if this approach can improve screening and reduce cancer deaths.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- multilevel training intervention (educational meetings, decision aids, FIT kits)
- What this could lead to
- If successful, this approach could help more people get screened for colorectal cancer and choose the test that fits them best, potentially reducing deaths from the disease.
- What could go wrong
- This is a small pilot study with only 44 doctors, so results may not apply widely. It tests a training program, not a new treatment, so the direct impact on cancer deaths is uncertain.
