Psoriasis is a chronic inflammatory skin condition that can have a debilitating impact on patients. It affects 2% of the UK population (Gelfand et al, 2005), and although it can develop at any age, usually occurs in adults rather than children (NHS Choices, 2015). General practice nurses (GPNs) will often encounter patients with psoriasis in their dayto- day practice, but can lack confidence when advising these patients on the effective management of the condition. This article outlines the causes of psoriasis and provides practical advice for GPNs on assessment and treatment in primary care. The author also outlines the psychological effects of psoriasis, and discusses referral guidelines.
