title: Three years after the publication of the German (S3) evidence based psoriasis guidelines--was it worth the effort?
abstract: The S3 (evidence-based) psoriasis guidelines were an important milestone in German dermatology. Three years after their publication, a review and evaluation of their success is important. Since the publication of the guidelines, the quality of care of psoriasis patients has improved. The proportion of patients with a PASI above 20 in the general patient population has decreased, there are less days of work lost due to psoriasis, uncertainties in administering systemic therapies have been decreased and the proportion of patients with severe psoriasis receiving a systemic treatment has increased. The guidelines' website as well as the original publication in the JDDG has been accessed more than 50,000 times. The guidelines' discussion was continued even after its publication and in further publications from within the group a therapeutic algorithm, treatment goals and indicators for the quality of care have been developed.
