The prevalence and clinical features of chronic obstructive pulmonary disease patients with traits of asthma in Taiwan

The application of the checkbox for identifying patients with traits of both chronic obstructive pulmonary disease (COPD) and asthma proposed by the 2015 Global Initiative for Asthma (GINA)/Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations has not been well studied although such identification is important in clinical practice. Thus, we aimed to investigate the prevalence and features of COPD coexistent with asthma traits diagnosed based on the 2015 GINA/GOLD strategies, and explore the gap between guidelines and routine practice in the diagnosis and pharmacological management of such condition in a COPD cohort.
