The majority of patients with psoriasis can be managed in primary care, although specialist care may be necessary at some point in up to 60% of cases. Patients with erythrodermic or generalised pustular psoriasis should be referred for a same day dermatological opinion, and if psoriatic arthritis is suspected, early referral for a rheumatological opinion is recommended. Recent guidance from NICE and SIGN will contribute significantly to the care of psoriasis sufferers in both primary and secondary care. [With external links to the evidence base]
