In this paper we consider whether methods currently used to measure utility of health outcomes are consistent with the equity criteria adopted by researchers. We show that unless the chosen equity criterion is incorporated in the design of the measurement instrument, the derived health state utilities are inconsistent with the equity criterion (except under special circumstances). Adjustment algorithms are derived, based on the axioms of von Neumann-Morgenstern utility theory, which take account of difference equity criteria currently adopted in the literature. The proposed approach is based on simple lottery questions of the type already used widely in empirical studies.
在本文中，我们探讨当前用于衡量健康结果效用的方法是否与研究人员采用的公平标准相一致。我们表明，除非在测量工具的设计中纳入所选的公平标准，否则得出的健康状态效用将与公平标准不一致（特殊情况除外）。基于冯·诺依曼-摩根斯坦效用理论的公理推导了调整算法，该算法考虑了文献中目前采用的不同公平标准。所提出的方法基于实证研究中已广泛使用的简单彩票问题类型。
