QALY‐maximisation and public preferences: results from a general population survey
通过一般人群调查，检验公众对QALY最大化模型中关键假设（如健康项目规模、风险水平和收益的边际社会价值恒定）的支持程度，发现数据与模型核心比例假设基本一致，但与以往研究结果相悖。
The appropriate criteria that should be used in setting priorities in a publicly funded health care system remain open to debate. From a health economics perspective, quality-adjusted life years (QALYs) are increasingly portrayed as a measure of societal value and the criterion of QALY maximisation is then advocated. This paper reports a study that investigated the extent to which some of the assumptions underlying the QALY maximisation approach, notably constant marginal societal value for increases in the size of health programmes, the level of risk, and the level of benefit are supported by members of the public. A general population interview-based survey was conducted. The survey design employed conjoint methods. In general, the public preference data from this study, in themselves, are not much at odds with the core proportionality assumptions concerning societal value in the QALY maximisation model assumptions. The data are, however, at odds with reports from various previous studies.
