Many patients are active smokers at the time of a diagnosis of surgically resectable lung cancer. Perioperative smoking cessation is associated with improved survival, but the cost-effectiveness of a smoking cessation program initiated immediately before surgery is unknown.
We developed a decision analytic Markov model to evaluate the incremental cost-effectiveness of a formal smoking cessation program. The parameter estimates were taken from the available literature. The model included the cost and effectiveness of the smoking cessation program, cost and incidence of perioperative complications, postoperative mortality, and utility measured in quality adjusted life years (QALY). Dollars per QALY and life year were calculated and one-way sensitivity analyses were performed.
The cost/QALY and cost/life year were $16,415 and $45,629 at 1 year after surgery and $2609 and $2703 at 5 years, respectively. Most sensitivity analyses showed the 1 year postsurgery cost/QALY estimates were less than $50,000, and all were less than $12,000 at 5 years. Cost-effectiveness estimates were most sensitive to the frequency of perioperative complications and the estimated short-term utility estimates.
A smoking cessation program initiated before surgical lung resection is cost-effective at both 1 and 5 years postsurgery. Providers should encourage patients who are still smoking to engage in formal smoking cessation programs.
许多患者在被诊断为可手术切除的肺癌时仍在积极吸烟。围手术期戒烟与生存率提高相关,但在手术前立即启动的戒烟计划的成本效益尚不清楚。
我们开发了一个决策分析马尔可夫模型,以评估正式戒烟计划的增量成本效益。参数估计取自现有文献。该模型包括戒烟计划的成本和效果、围手术期并发症的成本和发生率、术后死亡率以及以质量调整生命年(QALY)衡量的效用。计算了每QALY和每生命年的美元成本,并进行了单向敏感性分析。
术后1年的成本/QALY和成本/生命年分别为16415美元和45629美元,5年时分别为2609美元和2703美元。大多数敏感性分析表明,术后1年的成本/QALY估计低于50000美元,5年时均低于12000美元。成本效益估计对围手术期并发症的发生率和短期效用估计最为敏感。
在肺切除手术前启动的戒烟计划在术后1年和5年都是具有成本效益的。医疗服务提供者应鼓励仍在吸烟的患者参加正式的戒烟计划。
