Psoriasis is one of the most common skin diseases with a chronic and recurrent course. The disease requires systematic treatment and appropriate care. Therefore, in the care of the patient with psoriasis, there must also be place for health education. The aim of this study was to determine the need for health education among patients with psoriasis by determining knowledge gaps occurring most frequently. Materials for this study were collected using an anonymous questionnaire created on the basis of the Psoriasis Disability Index (PDI). The study group included 149 patients with psoriasis. It has been proven in previous studies that patients with psoriasis see the need to improve their knowledge of the disease and self-care methods, and the greatest deficit of their education refers to the factors activating the process of the disease and to the methods of prophylactics in psoriasis.
