This study aims to estimate the value of a statistical life (VSL) in the context of atherosclerotic cardiovascular disease (ASCVD) in Spain using a contingent valuation/standard gamble (CV/SG) chained approach.
The study employed a two-stage preference elicitation method that combined contingent valuation and a modified standard gamble technique. Specifically, willingness-to-pay and willingness-to-accept values were obtained for two health states depicting hypothetical outcomes following cardiovascular events. Subsequently, relative utility losses for the health states were derived using a modified standard gamble framing two risky choices. Chaining these elicited values allowed for VSL calculation without requiring direct valuation of small mortality risk reductions. The study was conducted through in-person interviews with a representative sample of 412 Spanish adults selected by stratified quotas.
The estimated VSL range is from 1.59 to 2.06 million euros. Minor differences emerge between VSL figures on the basis of each of the two health states. These VSL estimates for ASCVD are congruent with the recent update of the official VSL estimated for Spain in the context of road traffic accidents, though the upper limit of the range is slightly higher (almost 9%).
VSL estimates align with existing ranges in other European countries, particularly in the context of road safety, where a significant portion of existing studies is concentrated. Comparisons with other contexts, involving cardiovascular diseases, also lend support to the estimates presented here.
本研究旨在采用条件估值/标准博弈(CV/SG)链式方法,估计西班牙动脉粥样硬化性心血管疾病(ASCVD)背景下的统计生命价值(VSL)。
该研究采用了两阶段偏好诱导方法,将条件估值与改良的标准博弈技术相结合。具体而言,针对描述心血管事件后假设结果的两种健康状态,获取了支付意愿和接受意愿值。随后,使用构建两个风险选择的改良标准博弈得出这些健康状态的相对效用损失。将这些得出的值进行链接,无需对小幅度死亡风险降低进行直接估值即可计算VSL。该研究通过对412名西班牙成年人的代表性样本进行分层配额抽样并进行面对面访谈来开展。
估计的VSL范围为159万至206万欧元。基于两种健康状态各自得出的VSL数字之间存在细微差异。这些ASCVD的VSL估计值与西班牙在道路交通事故背景下官方VSL的最新估计值一致,尽管该范围的上限略高(近9%)。
VSL估计值与其他欧洲国家的现有范围一致,特别是在道路安全方面,现有研究的很大一部分集中于此。与涉及心血管疾病的其他背景进行比较,也支持此处给出的估计值。
