目的：我们评估旨在防止戒烟者重新使用香烟的预防吸烟复发干预措施的成本效益。由于复发预防是对戒烟努力的补充，因此对其成本效益的适当测试是它是否降低了戒烟的增量成本效益比（ICER）。本研究的主要目标就是进行这样的测试。方法：来自一项随机试验的数据，确定了预防吸烟复发的替代模式的有效性，并结合ICER戒烟评估，以评估预防吸烟复发是否具有成本效益。结果：该试验提供了令人信服的证据，表明预防复发在统计上显著降低了戒烟后24个月仍在吸烟的戒烟者的比例。干预效果足以提高戒烟ICER的分母项，从而抵消复发预防增加到成本分子项的数量。从这个意义上说，预防吸烟复发往往是物有所值的。结论：预防吸烟复吸是当前控制香烟消费努力的高成本效益补充。这类补充性卫生干预措施应采用不同于成本效益文献中常见的方法进行评估。
Objectives: We assess the cost-effectiveness of smoking relapse prevention interventions designed to keep quitters from resuming the use of cigarettes. Because relapse prevention is complementary to smoking cessation efforts, the appropriate test of its cost-effectiveness is whether it reduces the incremental cost-effectiveness ratio (ICER) of smoking cessation. The major goal of the study is to carry out such a test.Methods: Data from a randomized trial that ascertained the effectiveness of alternative modes of smoking relapse prevention are combined with ICER estimates of smoking cessation to assess whether relapse prevention is cost-effective.Results: The trial produced convincing evidence that relapse prevention yields statistically significant reductions in the proportion of quitters who are smoking at 24 months postquit. The intervention effects are substantial enough to raise the denominator terms of the smoking cessation ICER and, thereby, offset the amount relapse prevention adds to cost numerator terms. In this sense, smoking relapse prevention tends to pay for itself.Conclusions: Smoking relapse prevention is a highly cost-effective addition to current efforts to curb cigarette consumption. Complementary health interventions of this sort should be assessed by different methods than those commonly found in the cost-effectiveness literature.
