Objective We aimed to assess the cost-effectiveness of screening smokers and ex-smokers for lung cancer in the Netherlands. Methods A Markov model was used to evaluate the health effects and costs of lung cancer screening from the healthcare perspective. The effects and costs of ten screening scenarios with different start and stop ages of screening were examined across a lifetime horizon in a cohort of 100,000 smokers and ex- smokers 50 years and older. Results The incremental cost-effectiveness ratios (ICERs) of screening smokers and ex-smokers aged 50–60 years, 50–70 years, and 50 years and older are below the cost-effectiveness threshold of € 20,000 per quality adjusted life year (QALY) gained. Screening 50–60-year-old smokers and ex-smokers was the most cost-effective scenario with an ICER of € 14,094 per QALY gained. However, screening smokers and ex-smokers 50 years and older yielded the highest QALYs and resulted in an ICER of € 16,594 per QALY, which is below the threshold of € 20,000 per QALY. All screening scenarios compared to no screening resulted in CERs between the € 14,000 and € 16,000 per QALY gained. The efficiency frontier showed that screening smokers and ex-smokers in the age groups 70 years and older, 60–70 years, 60 years and older are excluded by extended dominance by no screening, screening smokers and ex-smokers aged 50–60 years and 50–70 years. Conclusion This study showed that lung cancer screening is cost-effective in the Netherlands. Ausführliche Beschreibung
