Compared with topical corticosteroids, topical combined active vitamin D 3 /corticosteroids and especially biologics are more expensive despite their marked efficacy in the treatment of psoriasis. The aim of the present study is to evaluate total costs as well as costs versus efficacy of various psoriasis treatments under the current Japanese health‐care insurance system. A prospective study was performed from the database of a single clinic located in Hokkaido Prefecture. Cost and quality of life of psoriatic patients were evaluated in a prospective manner during a total of 12 months from March 2017 until June 2018. Quality‐adjusted life year ( QALY ) of biologics was the highest among all treatments. Among the topical treatments, the cost versus efficacy of combined active vitamin D 3 /corticosteroid was lowest (¥10 557/1 Psoriasis Area and Severity Index). Furthermore, incremental cost‐effectiveness ratio ( ICER ) of combined active vitamin D 3 /corticosteroid was ¥1 024 031/ QALY when compared with topical corticosteroid treatment alone. The topical combined active vitamin D 3 /corticosteroid treatment showed the best cost‐efficacy in terms of medical economic burden.
