A search for covert precipitating clinical parameters in frequent exacerbators of chronic obstructive pulmonary disease

摘要

Introduction:Acute exacerbations are a significant source of morbidity and mortality associated with chronic obstructive pulmonary disease (COPD). Some patients suffer an inordinate number of exacerbations while others remain relatively protected. The aim of this study was to evaluate the potentially modifiable precipitating parameters of frequent severe exacerbations requiring hospital admission in COPD.
