Demographic, health behavioral, and self-management abilities associated with disease severity among patients with chronic obstructive pulmonary disease: An exploratory study.

This study aimed to identify the association between demographic characteristics, health behaviors, self-management abilities, and disease severity among patients with chronic obstructive pulmonary disease (COPD). The study was conducted from January to December 2015 in 4 hospitals in China. The DOSE index was assessed by grade of dyspnea (D), airflow obstruction (O), current smoking status (S), and frequency of exacerbation in the last year (E).
