在医疗保健的临床和经济评价中，应从公众角度确定所获得的利益价值。本研究的目的是建立附加到不同的健康状态的相对估值，形成的基础上，用于量化病人从医疗保健中受益的“社会关税”。3395个访谈进行了具有代表性的样本的成年英国人口。使用EuroQol健康状态分类和视觉模拟量表（VAS），每个受访者对15个健康状态进行了评估，总共对45个州进行了直接评估。大约10周后进行了221次重新访谈。生成了一个接近完整且逻辑一致的VAS数据集，具有良好的重测信度（平均ICC = 0.78）。社会阶层和教育都有显着的影响，其中较高的中位数评价是由受访者在社会阶层III-V和那些与中等或没有教育学历。这些影响对于更严重的状态尤其明显。在社会关税中使用这种估值提出了一些重要问题，涉及使用VAS方法本身来对假设的健康状况进行估值，根据社会阶层和/或教育程度制定单独的关税，以及适当衡量集中趋势。
In the clinical and economic evaluation of health care, the value of benefit gained should be determined from a public perspective. The objective of this study was to establish relative valuations attached to different health states to form the basis for a 'social tariff' for use in quantifying patient benefit from health care. Three thousand three hundred and ninety-five interviews were conducted with a representative sample of the adult British population. Using the EuroQol health state classification and a visual analogue scale (VAS), each respondent valued 15 health states producing, in total, direct valuations for 45 states. Two hundred and twenty-one re-interviews were conducted approximately 10 weeks later. A near complete, and logically consistent, VAS data set was generated with good test-retest reliability (mean ICC = 0.78). Both social class and education had a significant effect, where higher median valuations were given by respondents in social classes III-V and by those with intermediate or no educational qualifications. These effects were particularly noticeable for more severe states. The use of such valuations in a social tariff raises important issues regarding the use of the VAS method itself to elicit valuations for hypothetical health states, the production of separate tariffs according to social class and/or education and the appropriate measure of central tendency.
