Texts and referrals aim to catch lung cancer early in ER smokers
NCT ID NCT07566221
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether text messages and easy referrals can help more smokers get screened for lung cancer. About 1,036 emergency department patients who smoke or recently quit will be randomly assigned to receive a simple referral, a facilitated referral, or text message reminders. The goal is to see if these strategies increase the number of people who complete a low-dose CT scan within 120 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- text messaging and facilitated referral
- What this could lead to
- If successful, this could show simple ways to get more high-risk smokers screened for lung cancer, potentially catching it earlier.
- What could go wrong
- This is a behavioral study, not a drug trial. It may not increase screening rates much, and results might not apply to other settings.
