Do personal and societal preferences differ by socio‐demographic group?
研究利用美国2000年医疗支出面板调查数据，比较不同社会人口群体在EQ-5D指数（社区偏好）和EQ VAS（个人偏好）上的差异，发现差异很小且大多不显著，初步表明使用EQ-5D指数进行成本效果分析可能不会加剧社会人口不平等。
For equity, preferences used in cost-effectiveness analyses (CEAs) should yield similar values for different groups with similar health states. We used data from the US 2000 Medical Expenditure Panel Survey, including socio-demographics, EQ-5D Index and EQ Visual Analog Scale (EQ VAS) scores, to examine whether EQ-5D Index (representing community preferences) and EQ VAS (representing personal preferences) scores differed systematically by socio-demographic group. Differences between EQ-5D Index and EQ VAS scores by socio-demographic group were small and mostly not statistically significant. These preliminary findings suggest that using the EQ-5D Index in CEAs may not contribute to socio-demographic inequities.
