EQ-5D-3L量表两种中国效用积分体系的比较：基于西藏城乡居民的应用

Comparison of Two Chinese Value Sets of EQ-5D-3L Scale: Based on the Application of Urban and Rural Residents in Tibet

目的:比较EQ-5D-3L中国的两种效用积分体系在西藏自治区城乡居民应用的差异,为合理选择积分体系提供参考。方法:数据来源于西藏第五次国家卫生服务调查,用EQ-5D量表测量健康相关生命质量,运用Tobit模型分析影响健康效用值因素的差异。结果:在5个维度中,自我照顾存在的问题最少,疼痛或不舒服维度存在问题最多,2014版和2018版的积分体系下全人群的健康效用值分别为0.927 8和0.969 2,Tobit回归分析发现2018版的组间差异小于2014版。结论:2018版积分体系得到的健康效用值高于2014版,两种效用积分体系具有较好一致性,但一致性区间(0.32)明显大于最小显著性差异(MID)0.074,两种积分体系不可互相替代。

Objective: To compare the differences between EQ-5 D-3 L China’s two value sets in the application of urban and rural residents in Tibet Autonomous Region, and to provide a reference for the rational selection of the integral system. Methods: Data from Tibet’s fifth National Health Service Survey, the health-related quality of life was measured by the EQ-5 D scale. The Tobit model was applied to analyze differences in factors affecting health utility values. Results: Among these five dimensions, self-care had the least problems, and the pain or discomfort dimension had the most problems. The health utility values of the whole population in the 2014 and 2018 points were 0.927 8 and 0.969 2 respectively. Tobit regression analysis found that the difference between groups in 2018 was less than the 2014 version. Conclusion: The 2018 version of the value set had higher health utility value 2014 version. The two value sets had good consistency, but the consistency interval(0.32) was significantly larger than the minimum significant difference(MID) 0.074. The two value sets were not interchangeable.
