时间权衡法是测量健康效用值常见方法之一,其结果被广泛应用于EQ-5D量表积分体系的构建及计算质量调整生命年。传统时间权衡法在测量差于死亡健康状态时具有一定的局限,为此学者们开发出一系列新的时间权衡法来弥补传统方法的不足。文章对不同时间权衡法在健康效用值研究中的应用进行了阐述和比较,应根据研究目的的不同选择适宜的时间权衡法。对现有方法的完善和新方法的探索还有待进一步的深入研究。
Time trade-off is one of the common methods to measure health utility value. The results are widely used in the construction of the EQ-5D scale integration system and the calculation of quality adjusted life years. Traditional time trade-offs have some limitations in measuring poor health status of death, so scholars have developed a series of new time trade-offs to make up for the shortcomings of traditional methods. The article elaborates and compares the application of the trade-offs of different time in the study of the health utility value, and the suitable time trade-off should be chosen according to the different purposes of the research. The improvement of the existing methods and the exploration of new methods have yet to be further studied.
