Asthma in the workplace: a case-based discussion and review of current evidence.

The relationship between asthma and the workplace is important to consider in all cases of adult asthma. Early identification of a cause in the workplace offers an opportunity to improve asthma control significantly and reduce the need for long-term medication if further exposures to the cause can be avoided. This typical but fictitious case is designed to give the reader clinical information in the order this would normally be received in clinical practice, with a real-time commentary about management decisions. Pertinent recent guidance is cited to stress the importance of evidence-based practice.
