ABSTRACT
BACKGROUND: Currently, no formalized international consensus guidelines exist to direct optimal topical treatment including long-term treatment. OBJECTIVE: In this survey, we aim to examine if and which topicals are used in clinical practice in long-term continuous treatment of psoriasis and how topicals are used in treating specific sites of the body. METHODS: A questionnaire was distributed electronically to dermatologists from the International Psoriasis Council (IPC) representing 26 countries. RESULTS: The top three topicals used across all severities of disease were topical corticosteroids, vitamin D analogs, and potent topical corticosteroids in combination with vitamin D analogs. On locations where the skin is thin, flexural and genital psoriasis, lower potency topical corticosteroids were used, whereas on other sites, in particular in palmoplantar psoriasis, superpotent topical corticosteroids and combination vitamin D analogs/corticosteroids were used. CONCLUSIONS: It is relevant to optimize localized therapy for all severities of psoriasis reconciling disease activity (stable vs. unstable disease), localization of the lesions and the individual patient and his/her perspectives on disease control. Topical therapies are valuable treatments for classical mild disease and may have a position in some patients with more severe manifestations.

BACKGROUND: Topical treatment of mild to moderate psoriasis is first-line treatment and exhibits varying degrees of success across patient groups. Key factors influencing treatment success are physician topical treatment choice (high efficacy, low adverse events) and strict patient adherence. Currently, no formalized, international consensus guidelines exist to direct optimal topical treatment, although many countries have national guidelines. OBJECTIVE: To describe and analyse cross-regional variations in the use and access of psoriasis topical therapies. METHODS: The study was conducted as an observational cross-sectional study. A survey was distributed to dermatologists from the International Psoriasis Council (IPC) to assess topical therapy accessibility in 26 countries and to understand how body surface area (BSA) categories guide clinical decisions on topical use. RESULTS: Variation in the availability of tars, topical retinoids, dithranol and balneotherapy was reported. The vast majority of respondents (100% and 88.4%) used topical therapy as first-line monotherapy in situations with BSA < 3% and BSA between 3% and 10%, respectively. However, with disease severity increasing to BSA > 10%, the number of respondents who prescribe topical therapy decreased considerably. In addition, combination therapy of a topical drug and a systemic drug was frequently reported when BSA measured >10%. CONCLUSION: This physician survey provides new evidence on topical access and the influence of disease severity on topical usage in an effort to improve treatment strategies on a global level.
