Abstract

BACKGROUND

Profile instruments are frequently used to assess health-related quality of life and other patient-reported outcomes. However, preference-based measures are required for health-economic cost-utility evaluations.

RESULTS

Although regression-based approaches are commonly used to map from profile measures to preference measures, we show that this results in biased estimates because of regression to the mean.

CONCLUSIONS

Linking (scale-aligning) is proposed as an alternative.

摘要

背景

概况量表常用于评估与健康相关的生活质量和其他患者报告的结果。然而,健康经济成本效益评估需要偏好量表。

结果

尽管基于回归的方法常用于从概况量表到偏好量表的映射,但我们表明,由于回归均值,这会导致有偏估计。

结论

提出了链接(量表匹配)作为替代方法。
