title: Severity levels in psoriasis: a separate 'very severe' category not required.
abstract: This study assessed the need for a 'very severe (BSA > 20%)' category for psoriasis. Though impact on quality of life differs between severe (BSA 11-20%) and very severe groups, considerable overlap exists between them. BSA > 10% predicts severity sufficiently, deterring the need for a 'very severe' category. Severity was self-assessed and may not reflect true clinical severity.
