Objective: To investigate the patients with stable chronic obstructive pulmonary disease (COPD) to understand the use of double bronchodilator therapy and influencing factors.
Methods: The patients with stable COPD who used double bronchodilators were continuously enrolled in our hospital. The information of demographic characteristics, medical history, physical examination, drug use, and correct treatment methods after using inhaled drugs were collected by standardized questionnaire. Measurement data between groups were compared by using the independent sample t-test, and counting data between groups were compared by using the chi-square test.
Results: A total of 102 patients were included in the analysis. The proportion of patients with stable COPD who correctly used dual bronchodilators was 59.8% (61 patients). In the GOLD classification, the correct use rate of C-level patients was 69.8%, which was significantly higher than the used correct rate of D-level patients (49.0%) (P=0.032). In the age group, the correct use rate of patients <65 years old was 72.1%, which was significantly higher than that of patients ≥65 years old (50.8%) (P=0.031). In addition, education level, duration of drug use, and drug type may also affect the correct use of drugs, but no significant statistical significance was found between the groups of these three factors (P > 0.05).
Conclusion: There is still a gap between the treatment of dual bronchodilators in patients with stable COPD and the guidelines, so the management of COPD should be strengthened. Besides, the correct use rate could be affected by the GOLD classification and age.
