Background. Diagnosis of psoriasis arthritis (PsA) is often delayed in an outpatient dermatological setting. Therefore, we compiled a patient questionnaire (GEPARD, GErman Psoriasis ARthritis Diagnostic questionnaire) to detect PsA in psoriasis outpatients. Patients and methods. Initially, between 2005 and 2007, we evaluated GEPARD in the outpatient setting of our Department of Dermatology with the Vasey and Espinoza criteria. In May 2008, the questionnaire was distributed to practices in the Regensburg area, Germany. Patients who filled out the GEPARD questionnaire were invited for a rheumatological work-up and, where indicated, arthrosonography, conventional X-ray, MRI, and scintigraphy examinations were performed. PsA was classified on the basis of the CAS-PAR criteria. Results. We calculated a sum cut-off score of = 4 positive answers in the first cohort. Of all 54 patients examined 63% could be diagnosed with PsA according to the CASPAR criteria. After a complete work-up with all diagnostic means 79.6% (43 patients) could be detected with inflammatory joint manifestations. Conclusion. It is possible to detect PsA patients in a dermatologic outpatient setting with the GEPARD questionnaire.
