Chinese guidelines for childhood asthma 2016: Major updates, recommendations and key regional data

Objective: With increased industrialization and urbanization in China, pediatric asthma is becoming more prevalent. Despite a growing body of evidence, there remains a significant unmet need for adequate management of childhood asthma. The Subspecialty Group of Respiratory Diseases of the Society of Pediatrics, the Chinese Medical Association, and the editorial board of the Chinese Journal of Pediatrics have recently updated the "Guidelines for diagnosis and optimal management of asthma in children," first published in 2008. Methods: This article reviews the major updates to the guidelines and covers the main recommendations for diagnosis, assessment, and treatment of pediatric asthma in China. Key regional data on epidemiology, clinical features, disease burden, knowledge among children and parents, and risk factors including pollution are provided to contextualize the recommendations. Results: The major updates to the guidelines include: (1) A more practical definition of asthma; (2) assessment of asthma control that takes into account both current symptom control and future risk; (3) classification based on disease severity that corresponds with treatment step; (4) differentiation between difficult-to-treat and poorly controlled asthma; (5) an open-ended approach to pharmacological management; and (6) allergen immunotherapy (AIT) in mild- to moderate-persistent asthma. Conclusions: The updated "Guidelines for the diagnosis and optimal management of asthma in children (2016)" combine the latest national and international clinical evidence and experience to provide practical and reliable recommendations to Chinese clinicians.
