Consensus document on the evaluation and treatment of moderate‐to‐severe psoriasis: Psoriasis Group of the Spanish Academy of Dermatology and Venereology

Abstract

AbstractPsoriasis is a highly prevalent disease with a major impact on quality of life; therefore, appropriate patient management is mandatory. Given that many issues in psoriasis are controversial and not clearly defined by evidence‐based medicine, management of psoriasis is very variable. Expert consensus can generate practical guidelines for optimization of patient care. Much has changed since 2009, when the Consensus Document on the Evaluation and Treatment of Moderate to Severe Psoriasis was published by the Spanish Psoriasis Group (GEP) of the Spanish Academy of Dermatology and Venereology (AEDV). The objective of the present consensus document is to provide the dermatologist with updated recommendations for the evaluation and treatment of patients with moderate‐to‐severe plaque psoriasis. All active members of the GEP of the AEDV were invited to participate in the survey. The final group comprised 46 members from various areas of Spain and with substantial experience in managing psoriasis. A 3‐round Delphi process was used to reach consensus. Consistent agreement and consistent disagreement (consensus) required the achievement of at least two of the following three criteria: Criterion 1, which was based on the position occupied by the mean on a scale of 1–9 and an SD <2; Criterion 2, which was based on the median and interquartile range (IQR) on a scale of 1–9; Criterion 3, which considered the percentage of the voting experts on a scale of 1–9. The items studied were definition of severity, therapeutic objectives, indications for systemic treatment and biologic therapy, induction and maintenance periods, therapeutic failure, loss of response, relapse and rebound, continuous and intermittent therapy, screening of patients before treatment, adherence to therapy, follow‐up of treatment outcome, combination of drugs, transitioning and associated comorbidities. Consistent agreement or disagreement (consensus) was achieved for 198 items (agreement, 3 criteria 146 items, 2 criteria 43 items; disagreement, 3 criteria 9 items, 2 criteria 0 items) based on the criteria described above. Completion of the Delphi consensus process enabled a broad and experienced group of Spanish psoriasis experts to provide useful and practical guidelines for the management and treatment of patients with moderate‐to‐severe psoriasis, particularly in areas where evidence is lacking.
