Abstract

Purpose: The SF-6D Classification System was recently updated (SF-6Dv2). We performed a valuation survey to construct a value set for the SF-6Dv2 in Japan.

Methods: An online discrete choice experiment (DCE) with duration was used to estimate a value set for the SF-6Dv2 for Japan based on public preferences. The target sample number was 3800. Respondents were asked to complete 15 choice tasks. A conditional logit model that estimates interactions between time and each dimension was used to develop the value set.

Results: The collected sample included 3933 respondents for the DCE tasks. The results of all the unconstrained models showed some inconsistencies. In particular, inconsistencies in the two most severe levels of the role limitation (RL) and vitality (VT) dimensions were observed in all models. The number of inconsistencies was smallest in a core model (n = 3) and in a model for core and common health states (n = 2). The physical functioning (PF) and pain (PA) dimensions had the greatest influence on utility at the overall level across all models. RL, VT, and social functioning (SF) had smaller overall impacts on utility. The PF weights for the two most severe levels are much lower than those in the UK and Australia. The Japanese scores tended to be lower compared with the UK SF-6Dv2 scores.

Conclusion: We obtained a value set for Japan (model 5). With the development of this value set, it is now possible to calculate quality-adjusted life years for economic evaluation in Japan when the SF-6Dv2 has been used.

基于国际协议的日本 SF-6Dv2 估值调查。

目的：SF-6D 分级系统（SF-6Dv2）最近进行了更新。我们进行了一项估价调查，以构建日本 SF-6Dv2 的价值集：方法：我们采用了一个有持续时间的在线离散选择实验（DCE），根据公众的偏好来估算日本 SF-6Dv2 的价值集。目标样本数为 3800 人。受访者被要求完成 15 项选择任务。我们使用了一个条件对数模型来估算时间与每个维度之间的交互作用，从而建立价值集：收集到的 DCE 任务样本包括 3933 名受访者。所有无约束模型的结果都显示出一些不一致性。特别是在角色限制（RL）和活力（VT）这两个最严重的维度上，所有模型都出现了不一致。在核心模型（n = 3）和核心与常见健康状态模型（n = 2）中，不一致的情况最少。在所有模型中，身体功能（PF）和疼痛（PA）维度对效用的总体水平影响最大。RL、VT 和社会功能（SF）对效用的总体影响较小。两个最严重级别的 PF 权重远低于英国和澳大利亚。与英国的 SF-6Dv2 评分相比，日本的评分往往较低：结论：我们获得了一套适用于日本的值集（模型 5）。有了这一数值集，在日本使用 SF-6Dv2 进行经济评估时，就有可能计算出质量调整生命年。
