Digital Tool Doubles Lung Cancer Screening Eligibility Detection in Major Trial

Lung cancer screening with low-dose CT scans can detect cancer early and save lives, but remains significantly underused in the United States. A major barrier is incomplete smoking history documentation in medical records and limited time for patient-doctor discussions about screening benefits and risks.

Researchers conducted a large randomized trial across University of Utah Health and NYU Langone Health systems, studying 31,303 adults aged 50-79 with smoking histories. They tested whether adding a patient-facing digital tool called MyLungHealth to existing clinician decision support would improve screening rates compared to clinician tools alone.

The MyLungHealth tool worked through patient portals in English and Spanish, collecting detailed smoking histories and providing personalized education about screening risks and benefits. The study had two parts: identifying patients with uncertain eligibility (26,729 participants) and encouraging screening among clearly eligible patients (4,574 participants).

Results were significant: the patient-facing tool more than doubled new eligibility identification from 2.3% to 4.7%. Among clearly eligible patients, screening orders increased from 19.2% to 20.5%. While these relative improvements were substantial, absolute increases remained modest, suggesting room for more intensive interventions.

For health-conscious individuals, this research highlights the importance of accurate smoking history documentation and proactive screening discussions. Early lung cancer detection dramatically improves survival rates, making these screening improvements potentially life-saving for thousands of patients. The digital approach also demonstrates how technology can enhance preventive care without overwhelming healthcare providers, potentially serving as a model for other cancer screening programs.
