支付意愿在测量皮肤疾病负担中的意义与应用

Application and significance of willingness-to-pay in measuring the burden of skin diseases

"生物-心理-社会"的新型医学模式要求我们综合评价疾病的状态和负担,健康相关生活质量在疾病负担的测算中是一个重要的考量指标。传统的健康相关生活质量的评价方法有基于间距的测量方法和基于偏好相关的测量方法,后者包括健康效用和支付意愿等。本文系统介绍支付意愿,回顾其在皮肤疾病中的应用。目前关于皮肤疾病的支付意愿研究总体仍存在数量少、涉及皮肤病种类少、样本量小等问题。在对于皮肤疾病的卫生经济学评价的实际应用中,支付意愿作为治疗增益的近似指标,较以健康效用为指标的效用增益更具实用价值。随着卫生经济学研究在皮肤疾病中逐渐起步,皮肤疾病支付意愿等评价方法的重视程度增高,有望开展基于更大规模人群、涉及更多病种的皮肤疾病卫生经济学相关研究。

According to the new biopsychosocial medical model,status and burden of diseases should be evaluated comprehensively,and health-related quality of life can be an important measurement index of the burden of diseases.Conventional assessment methods for health-related quality of life include interval-based assessment methods and preference-based assessment methods(health utilities and willingness-to-pay).This review introduces willingness-to-pay,and summarizes its applications in skin diseases.However,at present,only a small quantity of small-scale studies are available on willingness-to-pay,with only a few kinds of skin diseases involved.In the application of health-economic assessment of skin diseases,willingness-to-pay can serve as an approximate index of benefit gains,and be more valuable in practice than health utilities(the index of utility gains).With the increase in health-economic researches on skin diseases,more attention is paid to the willingness-to-pay for skin diseases and other health-economic assessment methods,and large-scale health-economic assessment-related researches are expected to be conducted on more kinds of skin diseases.
