Background:
Pulmonary air leak (PAL) is one of the most frequent complications following lung resection. While its short-term clinical and economic impacts are well documented, the long-term economic value of interventions that reduce PAL duration remains poorly quantified. This study developed a novel methodological framework to estimate the long-term economic value of PAL reduction and to provide a rapid, quantitative approach for assessing the cost-effectiveness of related clinical interventions.
Methods:
We developed a hybrid decision-tree-Markov model simulating the natural history and health state transitions following pulmonary resection. Marginal analysis was applied to quantify the relationship between PAL duration (in days) and long-term costs (from both societal and healthcare system perspectives) as well as health outcomes measured in quality-adjusted life years (QALYs). Deterministic sensitivity analyses were performed on key model parameters to assess robustness.
Results:
Each additional day of PAL was associated with an increase in long-term societal costs of USD 390.4, healthcare system costs of USD 348.1, and a loss of 0.0087 QALYs. Using a willingness-to-pay (WTP) threshold equivalent to one times China's 2024 per capita GDP (USD 13,447.9), the monetized value of the QALY loss amounted to USD 117.6. Consequently, each 1-day reduction in PAL duration generated a total long-term economic benefit of USD 508.0 from a societal perspective and USD 465.7 from a healthcare system perspective. Sensitivity analyses confirmed the stability of these estimates across plausible parameter ranges.
Conclusions:
This study provides the first quantitative estimation of the long-term economic value of reducing PAL duration after lung resection. The derived marginal values offer a practical, evidence-based tool for rapidly evaluating the economic rationale of PAL-targeted interventions and can inform clinical decision-making, health technology assessment, and policy development in thoracic surgery.
