为降低天花板效应,增强对较轻健康状态的区分能力,欧洲生命质量小组在EQ-5D-3L量表的基础上开发出新的EQ-5D-5L量表。EQ-5D量表的测量结果需通过效用积分体系转化成健康效用值,目前,加拿大、西班牙、英国、乌拉圭、韩国及荷兰已构建起基于本国人群健康偏好的EQ-5D-5L效用积分体系。通过对上述国家构建的研究方案、测量方法、健康状态选取、样本估计、数据处理及模型结果等进行介绍和比较,以此为中国EQ-5D-5L积分体系的构建提供参考。
To reduce the ceiling effect and enhance its ability to discriminate between less-healthy conditions, the European Quality of Life team developed a new EQ-5D-5L based on the EQ-5D-3L scale. The EQ-5D measures need to be converted into health utility values through the utility integration system. At present, EQ-5D-5L utility points system has been constructed based on the health preferences of their populations in Canada, Spain, the United Kingdom, Uruguay, South Korea and the Netherlands. Through the introduction of the national research programs, measurement methods, health status selection, sample estimation, data processing and model results introduced and compared, so as to provide reference for the construction of EQ-5D-5L integral system in China.
