It has been demonstrated conclusively that value and utility preference scores have only ordinal properties. This means, as has been pointed out on numerous occasions, that the quality adjusted life year (QALY) is a mathematically impossible construct. The implications are profound: Some 30 years of health technology assessment is called into question due to a failure to recognize the well-documented limitations imposed by the axioms of fundamental measurement. The purpose of this commentary is provide a critical examination of this practice in recommendations for atopic dermatitis.
已经确凿地证明,价值和效用偏好分数仅具有序数属性。正如在许多场合所指出的,这意味着质量调整生命年(QALY)在数学上是一个不可能的概念。其影响是深远的:由于未能认识到基本测量公理所带来的有充分记录的局限性,约30年的卫生技术评估受到质疑。本评论的目的是对特应性皮炎建议中的这种做法进行批判性审视。
