Focus groups in Swedish psoriatic patients with pruritus

Pruritus is a common complaint among patients of psoriasis vulgaris of the chronic plaque type. Despite a high prevalence of pruritus in psoriasis, limited information is available on this subject. The aim was to assess patients' perspective of pruritus in psoriasis vulgaris of plaque type, by using focus groups. A total of 20 patients with chronic plaque psoriasis participated in focus group discussions and were divided into five groups, on different occasions. Themes for the discussion were introduced and moderated by the investigators. The focus groups created a proper atmosphere for discussion on different aspects of pruritus in psoriasis. The patients regarded themselves able to discriminate between pruritus and pain. Pruritus was most common on the lower back and legs. Stress, cold weather and skin dryness were seen as the most common worsening factors for pruritus. Sunbathing and application of emollients with or without steroids and calcipotriol cream were suggested as factors that relieved pruritus. Quality of life was affected in some patients, for instance they were reluctant to participate in social activities. Patients' perspectives on pruritus in psoriasis were important for a better understanding of this sensation. The information collected from the focus group discussions might be useful for further study in this area.
