Abstract
Economic evaluations are an important input to decision-making and priority-setting in the health care sector. Measuring preferences for health improvements, as the demand-side value (willingness to pay) of gaining a quality-adjusted life year (QALY), is one relevant component in the interpretation of the results from health economic evaluations. Our article addresses whether willingness to pay for a QALY (WTP-Q) is sensitive to the size of the health differences and the probability for improvement. We use data from a contingent valuation survey based on 1400 respondents conducted in the spring of 2014. The results show that the expectation of sensitivity to scope, or higher WTP to the larger expected quality of life improvement, is not supported. We find WTP-Q values that conform reasonably well to previous studies in Sweden.
摘要
经济评估是医疗保健领域决策和优先级设定的重要依据。衡量对健康改善的偏好，即获得质量调整生命年（QALY）的需求方价值（支付意愿），是健康经济评估结果解释的一个相关组成部分。我们的文章探讨了支付意愿是否对健康差异的大小和改善的可能性敏感。我们使用了 2014 年春季基于 1400 名受访者的问卷调查数据。结果表明，对范围敏感性的预期，或者对更大预期生活质量改善的更高支付意愿，没有得到支持。我们发现，支付意愿符合瑞典之前研究的合理范围。
