What this trial studies

This clinical trial evaluates the effectiveness of communicating a patient's 'pulmonary age' as a motivational tool for smoking cessation. It involves a cluster randomized controlled design with two groups: one receiving pulmonary age assessments and the other receiving standard care without this information. Patients aged 25 and older who have been smoking for over a year will participate, with assessments conducted at the start, six months, and twelve months after inclusion. The primary outcome is the rate of smoking cessation at six months, verified through exhaled carbon monoxide measurements.

Who should consider this trial

Good fit: Ideal candidates are adults aged 25 and older who have been smoking for at least one year.

Not a fit: Patients with known respiratory illnesses or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance smoking cessation rates by providing patients with a tangible measure of their lung health.

How similar studies have performed: While few studies have explored the use of pulmonary age in smoking cessation, existing research has shown mixed results, indicating this approach may be novel and untested.
