Psoriasis vulgaris (PsV) is a chronic skin condition that has a major impact on health-related quality of life (HRQOL).
To determine the individual burden of PsV on HRQOL using willingness to pay (WTP) instrument.
Fifty-one consecutive PsV patients were asked to evaluate their overall health and psoriasis affected health by visual analogue scale (VAS), and interviewed on 8 domains (physical, emotional, sleep, work, social, self-care, intimacy, and concentration) of HRQOL and WTP for a hypothetical cure in each domain. Two additional questions proposing 6 alternatives for therapy were also asked. The analysis is performed with descriptive and frequency statistics, Mann-Whitney and Kruskal-Wallis tests.
The domains ranked highly were: physical comfort (90%), social comfort (77%), emotional health (75%) and work (53%). The following tendencies concerning WTP for top four impacted domains were found: the median WTP were the highest in the top impacted domains; the younger patients were willing to pay more than the older ones; the highest median WTP amounts appear in the lowest income group; the highest median WTP is associated with smaller psoriasis affected health VAS scores. The largest proportion and number of patients (37.3%, n=19) stated preferences for the systemic therapy. The second preferred choice was the thalassotherapy (29.4%, n=15).
The utility and reliability of the instrument based on the assessment of WTP stated preferences for 8 domains of HRQOL for evaluation the individual burden of psoriasis were strongly supported.
寻常型银屑病（PsV）是一种慢性皮肤病，对健康相关生活质量（HRQOL）有重大影响。
使用支付意愿（WTP）工具确定PsV对HRQOL的个体负担。
连续51例PsV患者被要求通过视觉模拟量表（VAS）评估其整体健康状况和银屑病对健康的影响，并就HRQOL的8个领域（身体、情绪、睡眠、工作、社交、自我护理、亲密关系和注意力）以及每个领域假设治愈的WTP进行访谈。还询问了另外两个提出6种治疗方案的问题。采用描述性和频率统计、Mann-Whitney检验和Kruskal-Wallis检验进行分析。
排名靠前的领域是：身体舒适度（90%）、社交舒适度（77%）、情绪健康（75%）和工作（53%）。发现了关于前四个受影响领域WTP的以下趋势：受影响最大的领域中WTP中位数最高；年轻患者比老年患者愿意支付更多；WTP中位数最高出现在收入最低的群体中；WTP中位数最高与银屑病对健康影响的VAS评分较低相关。最大比例和数量的患者（37.3%，n = 19）表示倾向于全身治疗。第二受欢迎的选择是海水疗法（29.4%，n = 15）。
基于对WTP评估的工具用于评估银屑病个体负担，在HRQOL的8个领域陈述偏好方面的效用和可靠性得到了有力支持。
