PROMETHEE: A Shared Interregional Tele-Tobacco Cessation Platform Embedded Within the IMPULSION Lung Cancer Screening Program

This prospective observational study aims to evaluate whether an intensive tele-tobacco cessation program delivered through the PROMETHEE platform improves smoking cessation among smokers participating in the French national lung cancer screening pilot program IMPULSION. Participants receiving the PROMETHEE pathway will be compared with matched controls receiving standard smoking cessation support available through IMPULSION. The primary endpoint is self-reported smoking cessation at 12 months.
