Abstract

This paper compares the relative performance of quality adjusted life years (QALYs) based on quality weights elicited by rating scale (RS), time trade-off (TTO) and standard gamble (SG). The standard against which relative performance is assessed is individual preference elicited by direct ranking. The correlation between predicted and direct ranking is significantly higher for TTO-QALYs than for RS-QALYs and SG-QALYs. This holds both based on mean Spearman rank correlation coefficients calculated per individual and based on two social choice rules: the method of majority voting and the Borda rule. Undiscounted TTO-QALYs are more consistent with direct ranking than discounted TTO-QALYs.

摘要

本文比较了基于通过评级量表（RS）、时间权衡法（TTO）和标准博弈法（SG）得出的质量权重的质量调整生命年（QALYs）的相对表现。评估相对表现所依据的标准是通过直接排序得出的个人偏好。与RS-QALYs和SG-QALYs相比，TTO-QALYs的预测值与直接排序之间的相关性显著更高。这一结论在基于每个个体计算的平均斯皮尔曼等级相关系数以及基于两种社会选择规则：多数投票法和博尔达规则的情况下均成立。未贴现的TTO-QALYs比贴现的TTO-QALYs与直接排序更一致。
