A comparison of patient and general population weightings of EQ‐5D dimensions
比较患者自评当前健康状态与普通人群评价假设健康状态在EQ-5D维度上的权重差异，发现焦虑/抑郁在患者模型中影响最大，而疼痛/不适在普通人群模型中影响最大。
This paper examines the differences in health state evaluations given by patients when they are asked to value their own current states, and those given by members of the general population who were asked to value hypothetical health states. Patient data consist of 4137 observations on EQ-5D profiles and Visual Analogue Scale (VAS) obtained from 3376 patients, covering eight different conditions. General population data are taken from the EQ-5D valuation set. Two analyses were carried out. In the first, the patient self-rated VAS was compared with population VAS values for the same health states. In the second, the patient self-rated VAS values were modelled, and the regression coefficients were compared with the corresponding coefficients from the general population study. The first analysis resulted in a statistically significant mean difference of -0.012 (0.647 for patient VAS, 0.659 from the population value set). The second analysis found statistically significant differences between the coefficients for the EQ-5D health dimensions Pain/Discomfort, Mobility and Anxiety/Depression. Anxiety/Depression had the largest impact on the patient model compared with Pain/Discomfort in the general population model. A further regression analysis suggests that the magnitude of disagreement between patient self-rated VAS model and the population VAS model depends on the patients' condition.
