这篇论文表明，QALYs可以从比文献中迄今为止认为的更基本的条件中推导出来：它足以在每个健康状态的生命年中施加风险中性。qaly的这种派生很有吸引力，因为它不需要效用理论概念的知识，例如效用独立性。因此，我们的公理化极大地促进了质量分析在医疗决策中的规范性（非）有效性的评估。此外，风险中立性可以很容易地在实验设计中进行测试，这使得评估qaly的描述性（非）有效性变得简单。
This paper shows that QALYs can be derived from more elementary conditions than thought hitherto in the literature: it suffices to impose risk neutrality for life years in every health state. This derivation of QALYs is appealing because it does not require knowledge of concepts from utility theory such as utility independence. Therefore our axiomatization greatly facilitates the assessment of the normative (non)validity of QALYs in medical decision making. Moreover, risk neutrality can easily be tested in experimental designs, which makes it straightforward to assess the descriptive (non)validity of QALYs.
