This report provides clinicians with recommendations for the diagnosis and management of asthma. These recommendations are organized into four components of therapy: measures of assessment and monitoring, control of factors contributing to asthma severity, pharmacologic therapy, and education for a partnership in asthma care. The recommendations are an update of the 1991 "Expert Panel Report: Guidelines for the Diagnosis and Management of Asthma." The recommendations are based on the available scientific literature and the consensus of the expert panel.
