INTRODUCTION To evaluate the cost-effectiveness of a number of follow-up guidelines and variants for subsolid pulmonary nodules. METHODS We used a simulation model informed by data from the literature and the National Lung Screening Trial to simulate patients with a ground glass nodule detected at baseline CT undergoing follow-up. Nodules were allowed to grow and develop solid components over time. We tested guidelines generated by varying follow-up recommendations for low-risk nodules, i.e. pure ground glass nodules or those stable over time. For each guideline, we computed average U.S. costs and quality-adjusted life-years (QALYs) gained per patient and identified the incremental cost-effectiveness ratios (ICERs) of those on the efficient frontier. In addition, we compared the costs and effects of the most recently released version of Lung-RADS, v1.1, with the previous version, v1.0. Finally, we performed sensitivity analyses of our results by varying several relevant parameters. RESULTS Relative to no follow-up, the follow-up guideline system that was cost-effective at a willingness-to-pay of $100,000/QALY and had the greatest QALY assigned low-risk nodules a 2-year follow-up interval and stopped follow-up after 2 years for ground glass nodules and after 5 years for part-solid nodules; this strategy yielded an ICER of $99,970. Lung-RADS v.1.1 was found to be less costly but no less effective than Lung-RADS v1.0. These findings were essentially stable under a range of sensitivity analyses. CONCLUSION Ceasing follow-up for low-risk subsolid nodules after 2-5 years of stability is more cost-effective than perpetual follow-up. Lung-RADS v1.1 was cheaper but similarly effective to v1.0.

高危患者亚实性肺结节随访的成本效益

引言 评估一些针对亚实性肺结节的随访指南和变体的成本效益。方法 我们使用由文献和国家肺筛查试验数据提供的模拟模型来模拟在基线 CT 中检测到磨玻璃结节的患者进行随访。随着时间的推移,允许结节生长并形成固体成分。我们测试了由针对低风险结节(即纯磨玻璃结节或随时间稳定的结节)的不同后续建议生成的指南。对于每个指南,我们计算了每位患者在美国的平均成本和质量调整生命年 (QALY),并确定了有效前沿患者的增量成本效益比 (ICER)。此外,我们比较了最新发布的 Lung-RADS 版本的成本和效果,v1.1,与之前的版本 v1.0。最后,我们通过改变几个相关参数对我们的结果进行了敏感性分析。结果 相对于无随访,在愿意支付 100,000 美元/QALY 且具有最大 QALY 的随访指南系统中具有成本效益,分配低风险结节为 2 年随访间隔并停止磨玻璃结节 2 年后随访,部分实性结节 5 年后随访;这一策略产生了 99,970 美元的 ICER。发现 Lung-RADS v.1.1 比 Lung-RADS v1.0 成本更低,但效果并不差。在一系列敏感性分析下,这些发现基本上是稳定的。结论 低风险亚实性结节稳定 2-5 年后停止随访比永久随访更具成本效益。Lung-RADS v1.1 更便宜,但效果与 v1.0 相似。与之前的版本 v1.0. 最后,我们通过改变几个相关参数对我们的结果进行了敏感性分析。结果 相对于无随访,在愿意支付 100,000 美元/QALY 且具有最大 QALY 的情况下具有成本效益的随访指南系统分配了低风险结节,随访间隔为 2 年并停止磨玻璃结节 2 年后随访,部分实性结节 5 年后随访;这一策略产生了 99,970 美元的 ICER。发现 Lung-RADS v.1.1 比 Lung-RADS v1.0 成本更低,但效果并不差。在一系列敏感性分析下,这些发现基本上是稳定的。结论 低风险亚实性结节稳定 2-5 年后停止随访比永久随访更具成本效益。Lung-RADS v1.1 更便宜,但效果与 v1.0 相似。与之前的版本 v1.0. 最后,我们通过改变几个相关参数对我们的结果进行了敏感性分析。结果 相对于无随访,在愿意支付 100,000 美元/QALY 且具有最大 QALY 的随访指南系统中具有成本效益,分配低风险结节为 2 年随访间隔并停止磨玻璃结节 2 年后随访,部分实性结节 5 年后随访;这一策略产生了 99,970 美元的 ICER。发现 Lung-RADS v.1.1 比 Lung-RADS v1.0 成本更低,但效果不亚于 Lung-RADS v1.0。在一系列敏感性分析下,这些发现基本上是稳定的。结论 低风险亚实性结节稳定 2-5 年后停止随访比永久随访更具成本效益。Lung-RADS v1.1 更便宜,但效果与 v1.0 相似。
