Bronchial asthma (hereinafter referred to as asthma in this text) is one of common chronic respiratory diseases, and its global prevalence has been on the rise over the recent years. Clinical studies and practices show that standardized diagnosis and treatment, plus practically effective management, are important to achieve better asthma control and quality of life. The Asthma Workgroup, CMA Society of Respiratory Diseases, revised the Chinese Guidelines for Prevention and Treatment of Bronchial Asthma (hereinafter referred to as the Guidelines) twice, in 2003 and 2008.
