The Psoriasis Symptom Inventory (PSI) is a patient-reported outcome measure designed to assess psoriasis signs and symptoms.
The aim was to assess the usefulness of the PSI in enhancing patient care in the clinical setting.
Eight dermatology clinics in six countries enrolled adults representing the full spectrum of psoriasis severity who regularly received care at the clinic. Patients were administered the eight-item PSI (score range 0-32; higher scores indicate greater severity) while waiting for the physician; the physician conducted a static physician global assessment (sPGA) and estimated psoriasis-affected body surface area (BSA) at the same visit. Physicians completed a brief questionnaire after each patient visit, and were interviewed about the PSI after all patients were seen.
The clinics enrolled 278 patients; mean [standard deviation (SD)] psoriasis-affected BSA was 7.6% (11.4). Based on BSA, 47.8% had mild psoriasis, 29.1% had moderate psoriasis, and 23.0% had severe psoriasis. Based on sPGA, 18.7% were clear/almost clear, 67.3% were mild/moderate, and 14.0% were severe/very severe. The mean (SD) PSI total score was 12.2 (8.3). Physicians spent a mean (SD) 4.9 (4.8) min discussing PSI findings with their patients (range 0-20 min). Key benefits of PSI discussions included the following: new information regarding symptom location and severity for physicians; prompting of quality-of-life discussions; better understanding of patient treatment priorities; change in treatment regimens to target specific symptoms or areas; and improvement of patient-physician relationship.
The PSI was useful for treated and untreated patients to enhance patient-physician communication, and influenced treatment decisions.
银屑病症状量表（PSI）是一种患者报告的结局测量工具，旨在评估银屑病的体征和症状。
评估 PSI 在增强临床环境中患者护理的实用性。
六个国家的八个皮肤科诊所招募了代表银屑病严重程度全貌的成年患者，这些患者经常在诊所接受治疗。在等待医生就诊时，患者接受了八项 PSI 评估（评分范围 0-32；得分越高表示病情越严重）；医生在同一就诊时进行了静态医生总体评估（sPGA）并估计了银屑病受累的体表面积（BSA）。每位患者就诊后，医生都会完成一份简短的问卷，并在所有患者就诊后对 PSI 进行访谈。
诊所共招募了 278 名患者；平均（标准差）银屑病受累 BSA 为 7.6%（11.4）。根据 BSA，47.8%的患者为轻度银屑病，29.1%为中度银屑病，23.0%为重度银屑病。根据 sPGA，18.7%的患者为清除/几乎清除，67.3%为轻度/中度，14.0%为重度/非常重度。PSI 总分的平均（标准差）为 12.2（8.3）。医生与患者讨论 PSI 结果平均花费 4.9（4.8）分钟（范围 0-20 分钟）。PSI 讨论的主要好处包括以下内容：医生获得有关症状部位和严重程度的新信息；引发生活质量讨论；更好地了解患者的治疗重点；调整治疗方案以针对特定症状或部位；改善医患关系。
PSI 对治疗和未治疗的患者均有用，可增强医患沟通，并影响治疗决策。
