Patients with psoriasis attending general practitioner and dermatology clinics may complain about their joints, but it may be difficult for the nonrheumatologist to distinguish psoriatic arthritis (PsA) from other forms of arthritis. A screening tool for PsA would therefore be useful to both general practitioners and dermatologists and help identify patients for further evaluation by a rheumatologist. Although several screening tools have been developed, the Psoriasis Epidemiology Screening Tool (PEST) has the advantage of simplicity and ease of use. This new instrument consists of 5 simple questions supported by the addition of a manikin for patient markup. During development, the questionnaire has shown a sensitivity of 0.94 and a specificity of 0.78. Further validation of this and the other questionnaires is now required. A "head to head" study of the PEST, ToPAS (Toronto Psoriatic Arthritis Screening questionnaire), and PASE (Psoriatic Arthritis Screening and Evaluation) tools is planned in a secondary-care population with psoriasis. This study is important not only to confirm the comparative performance of the instruments, but also to confirm the high figures for sensitivity in a secondary-care population.
就诊于普通科医生和皮肤科诊所的银屑病患者可能会抱怨关节问题，但非风湿病专家可能难以将银屑病关节炎（PsA）与其他类型的关节炎区分开来。因此，一种用于筛查 PsA 的工具对普通科医生和皮肤科医生都很有用，并有助于将患者识别出来以供风湿病专家进一步评估。尽管已经开发出了几种筛查工具，但银屑病流行病学筛查工具（PEST）具有简单易用的优点。这种新工具由 5 个简单的问题组成，并附有一个患者标记的人体模型。在开发过程中，该问卷的敏感性为 0.94，特异性为 0.78。现在需要对该问卷和其他问卷进行进一步验证。计划在二级保健人群中进行 PEST、ToPAS（多伦多银屑病关节炎筛查问卷）和 PASE（银屑病关节炎筛查和评估）工具的“面对面”研究。这项研究不仅对于确认这些工具的比较性能很重要，而且对于确认二级保健人群中高敏感性数字也很重要。
