Basic Therapeutic Approach for Patients with Plaque Psoriasis: Korean Expert Consensus Using the Modified Delphi Method

초록

Background: Currently, there is no consensus on the treatment of psoriasis in Korean pa- tients. Objective: This study aimed to establish a consensus on the basic therapeutic principles for Korean patients with plaque psoriasis. Methods: Using the modified Delphi method, a steering committee proposed 53 statements for the first Delphi round, which covered five subjects: (1) the goal of treatment and evalu- ation of disease severity, (2) topical therapy, (3) phototherapy, (4) conventional systemic therapy, and (5) biologic therapy. The panel of dermatologists scored the level of agreement for each statement on a ten-point scale with scores ranging from 1 (strongly disagree) to 10 (strongly agree). After discussing the results of the first round, the committee reformulated 41 statements. Finally, consensus was defined as more than 70% of the second round scores being ≥7. Results: The panel participants strongly agreed that the ideal treatment goals for Korean pa- tients with plaque psoriasis should include complete skin clearance and high dermatological quality of life. A strong consensus was also reached on the use of topical agents for psoriasis of any severity, the consideration of phototherapy before biologics therapy, the conventional systemic agents for moderate-to-severe psoriasis, and the recommendation of biologic for retractable psoriasis to conventional systemic therapy and phototherapy. Conclusion: This modified Delphi panel established an expert consensus on the therapeutic approach for Korean patients with plaque psoriasis. This consensus may improve the treat- ment outcomes for psoriasis in Korea.
