伤残权重方法学研究进展

Progress in researches on methodology of disability weight

伤残权重(DW)表示某特定伤残状态健康损失的严重程度,是估算伤残调整生命年(DALY)的一个重要指标。目前DW估算主要分为基于全球疾病负担的伤残权重(GBD DW)和基于健康相关生命质量的健康状态权重(HRQOL HSW)2种。为促进DW的进一步发展,本文对DW这2种方法学研究的评估人群、健康状态定义和评估方法进行了综述比较,从而分析不同方法的优缺点,为DW研究方法的改进提供综合参考依据。

Disability weight(DW),one of important indicators for estimating disability-adjusted life years(DALY),represents the severity of health loss in a particular disability state.Currently,DW has two sets of methodology named as“disability weight from the Global Burden of Disease Study”(GBD DW)and“health status weight from Health-Related Quality of Life”(HRQOL HSW).In order to promote the further development of DW methodology,this study briefly reviewed and compared these two sets of methodological study,including the respondents for the assessment,definition of health status,assessment methods and the methods’strength and weakness,which would provide a comprehensive reference for the improvement of DW research.
