The level of adherence to treatment by patients with psoriasis is low. Previous studies showed that results of psoriasis treatment are significantly influenced by the level of medication adherence. We evaluated the level of adherence to treatment by patients with psoriasis and its association with Psoriasis Area and Severity Index (PASI), Body Surface Area (BSA), Dermatology Quality of Life Index (DLQI) using author's questionnaire. The research included 60 patients with psoriasis. Skin lesions have been evaluated using PASI and BSA. Patients completed DLQI and the author's own questionnaire about adherence to treatment. PASI>10 and BSA>10 was received by 66.6% of patients, PASI<10 and BSA<10-25% of patients. As much as 76.6% of patients declared that the disease moderately or significantly lowers their quality of life. According to the questionnaire, 41.7% patients suffering from psoriasis showed poor adherence to treatment. Patients with PASI>10 and BSA>10 and DLQI>6 achieved a statistically significant higher result (worse adherence) in the author's own questionnaire when compared to patients with PASI<10 and BSA<10 and DLQI ≤ 6. A better understanding of the determinants of adherence can improve the outcomes of psoriasis treatment and lead to higher patient satisfaction.
