Role and challenges of severe asthma services: insights from the UK registry.

Severe bronchial asthma affects at least 5% of the asthmatic population and remains a clinical challenge. Data from the UK National Registry for Severe Asthma suggest that dedicated centers may improve asthma control, quality of life, reduce healthcare use and oral steroid burden. A multidisciplinary approach through complete lung function evaluation, optimization of adherence to treatment and immunological characterization are key issues to improve patients' care. In this paper, we provide an overview of the challenges of managing patients with severe asthma and the role of dedicated services.
