背景。人们越来越有兴趣将干预措施对无酬护理人员的影响纳入经济评估。目前的方法侧重于使用健康措施（忽略了与护理相关的生活质量的重要方面）或使用特定于护理人员的总评分措施（不基于偏好）。客观的。估计基于偏好的指数值，以衡量护理体验的概况（护理体验量表）。方法。最佳-最差量表实验中包含了护理人员体验量表中的 18 个资料。在每个配置文件中，受访者被要求从配置文件中选择最好和最差的属性级别。这项选择任务是由来自英国 5 个地理位置的 162 名无偿老年人护理人员通过邮寄问卷完成的。使用逻辑回归来估计护理者体验量表属性水平的效用权重。采用替代建模假设来确定参数估计的稳定性。这些参数估计值经过重新调整，以便护理人员体验量表的概况指数值处于 0 到 100 的范围内。结果。结果表明，与护理体验的其他属性相比，低水平的“活动”和“相处”会导致更大的效用下降。一般来说，底层和中层属性之间的差异比中层和顶层属性之间的差异更有价值。替代建模方法对指数值的影响可以忽略不计。结论。本研究报告的指数值提供了一种新的基于偏好的方法，将对护理人员的影响纳入经济评估，重点关注与护理（而不是健康）相关的生活质量。
Background. There is growing interest in incorporating the effects of interventions on unpaid carers in economic evaluation. Current methods focus on using health measures (which neglect important aspects of care-related quality of life) or using carer-specific sum score measures (which are not preference based). Objective. To estimate preference-based index values for a profile measure of the caring experience (the Carer Experience Scale). Methods. Eighteen profiles from the Carer Experience Scale were included in a best-worst scaling experiment. In each profile, respondents were asked to pick the best and worst attribute level from the profiles. The choice task was completed in a postal questionnaire by 162 unpaid carers of older people from 5 geographical locations in the United Kingdom. Logistic regression was used to estimate utility weights for the attribute levels of the Carer Experience Scale. Alternative modeling assumptions were employed to determine the stability of the parameter estimates. These parameter estimates were rescaled so that the profile index values for the Carer Experience Scale lay on a 0-to-100 scale. Results. The results indicate that low levels of "activities" and "getting on" result in larger decrements to utility than other attributes of the caring experience. In general, greater value is placed on differences between the bottom and middle levels of attributes than between the middle and top levels. Alternative modeling approaches had a negligible effect on the index values. Conclusion. The index values reported in this study offer a new preference-based approach to incorporating the effects on carers in economic evaluation, focusing on care (rather than health)-related quality of life.
