Nudge study aims to boost lung cancer screening rates
NCT ID NCT05832008
First seen Jun 27, 2026 · Last updated Jul 23, 2026 · Updated 2 times
Summary
This study tests whether sending text reminders to patients and alerts to their doctors can increase the number of people who get yearly lung cancer screening or follow-up tests. About 825 patients and their clinicians are taking part. The goal is to see if these simple nudges improve adherence to screening guidelines.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Patient and clinician nudges (text messages and EHR prompts)
- What this could lead to
- If successful, this could show simple reminders help more people get regular lung cancer screening and follow-up, potentially catching cancer earlier.
- What could go wrong
- This is a behavioral study, not a treatment trial. Results may vary by clinic and patient population, and nudges may not work for everyone.

Inclusion Criteria: Clinicians will be eligible if they: 1. are practicing primary care or specialty care physicians at a recruiting site within the University of Pennsylvania Health System; 2. care for patients who completed LCS via LDCT in 2019-2023; and 3. do not opt-out of study participation. Patients will be eligible if they: 1. are eligible for LCS based on 2021 US Preventive Services Task Force (USPSTF) population guidelines (aged 50-80; smoking history of 20-pack years; smoked within the last 15 years) 2. completed LCS via LDCT in 2019-2023; 3. have not been diagnosed with lung cancer; 4. meet criteria for non-adherence; 5. remain eligible for LCS during the trial enrollment period; and 6. receive LCS care from a clinician that has not opted-out of study participation Exclusion Criteria: Patients will be excluded if they: a) have a highly suspicious baseline LDCT (Lung-RADS 4B/X) given the presence of existing clinical pathways to ensure adherence in this group
