Objectives: Psoriasis is a chronic skin disease requiring a multidimensional approach, given its varying appearance, presence of comorbidities and complex treatment regimens. Psoriasis care is however often performed fragmented and, in case of flares, reactive with little integrated information on and for the patient. Literature suggests a multileveled approach of psoriasis, but the effects of its implementation have not yet been validated. The aim of this study is to analyze the impact of a multileveled psoriasis consultation format, named PsoPlus, which has been implemented since 2012 in the Department of Dermatology at Ghent University Hospital in Belgium.Methods: The patient population was divided into two groups: one following the regular consultation and one following the PsoPlus format. Demographic data, clinical outcome and treatment approach of psoriasis patients were compared.Results: Patients who opted for the specialized PsoPlus consultation were younger and had longer disease duration. Decision parameters such as disease severity and quality of life were reported more often in the PsoPlus group. In the latter, a higher rate of patients were started on systemic therapy compared to the regular consultation group, and reporting on adverse events was done more frequently. Conclusion:The implementation of a specialized consultation with comprehensive guidance facilitates documentation on disease-relevant parameters such as disease severity and quality of life. This format can be seen as a guidance for capturing data in a structured manner, with evidence showing that it significantly impacts treatment decision, treating not only psoriasis but the patient as a whole.

This study provides clinical evidence that CMN may influence the age of onset of vitiligo and trigger the development of halo naevi in patients with vitiligo.
