Title: A Prospective Study of Salvational Intervention With ICS/LABA for Reducing Chronic Obstructive Pulmonary Disease Exacerbation Under Severe Air Pollution (SIRCAP) in Beijing
Brief Summary: This is a multi-center, prospective, randomized and standard treatment parallel control clinical trial.A total of 764 stable COPD patients according to GOLD will be recruited and equally divided into two parallel groups, salvational intervention group (SI group) and control group (CT group).On the foundation of basic medicine, inhaled ICS/LABA will be used as an intervention drug for patients in SI group on severe air pollution days. It is aimed to evaluate whether this novel treatment strategy will decrease the frequency of AECOPD per year.
