Important parameters for cost-effective implementation of lung cancer screening

Area of Science:

• Pulmonary Medicine
• Health Economics
• Radiology

Background:

• Low-dose computed tomography (LDCT) screening is accepted for reducing lung cancer mortality and late-stage diagnoses.
• Balancing reduced mortality with the economic costs of screening programs is essential.
• Health economic models show significant variation in cost-effectiveness, influenced by national healthcare costs and program design.

Purpose of the Study:

• To identify the most clinically and cost-effective lung cancer screening programs.
• To minimize the total financial impact of LDCT screening.
• To inform optimal implementation strategies for LDCT screening programs.

Main Methods:

• Analysis of health economic models using UK costs and a targeted screening approach.
• Evaluation of various program components influencing cost-effectiveness.
• Consideration of factors like population selection, participation rates, screening intervals, nodule management, and clinical work-up.

Main Results:

• Recent UK-based modeling suggests most targeted screening scenarios fall within the willingness-to-pay threshold.
• Key modifiable program components significantly impact cost-effectiveness.
• Further research is needed to assess personalized screening intervals based on risk.

Conclusions:

• Optimizing lung cancer screening program components is critical for cost-effectiveness.
• Careful management of the medical infrastructure and workforce burden is necessary for LDCT implementation.
• Personalized screening strategies may offer future cost-effectiveness improvements.
