Abstract:
Objective:To understand the medication treatment rate and its associated factors among chronic obstructive pulmonary disease (COPD) patients aged ≥40 years in China, and to provide basic data for targeted interventions to improve the diagnosis and treatment of COPD patients.Methods:Data were from COPD surveillance of Chinese residents in 2014-2015. Questionnaire and pre-bronchodilator and post-bronchodilator spirometry were performed on all respondents. Individuals with post-bronchodilator FEV 1/FVC<70% were diagnosed as COPD patients. A total of 9 120 COPD patients were included in the analysis. Based on the complex sampling design, the medication treatment rate and 95% CI among COPD patients were estimated, and the associated factors were analyzed. Results:The medication treatment rate for COPD patients aged ≥40 years was 11.7% (95% CI: 10.2%-13.0%), the treatment rate with inhaled medication was 3.4% (95% CI: 2.9%-4.0%), and the treatment rate with oral or intravenous medication was 10.4% (95% CI: 9.0%-12.0%). All treatment rates were higher in patients who knew that they had COPD before the investigation. The rate of medication treatment in patients aged ≥60 years was higher than that in patients aged <60 years. Medication treatment rate, and oral or intravenous medication treatment rate among women were higher than those among men. These two treatment rates in patients with harmful occupational exposure were higher than those in patients without exposure. The medication treatment rate, and oral or intravenous medication treatment rate in former smokers were higher than those in current smokers and never smokers. Patients who knew that they had COPD before the investigation had higher rates of three treatments than those who were not aware of their disease conditions. Those with respiratory symptoms had higher three treatments rates than those without symptoms. Conclusion:In China, the rate of medication treatment for COPD patients aged ≥40 years old, especially the rate of inhaled medication treatment was very low. Being aware of their own COPD status and the emergence of respiratory symptoms were important factors associated with COPD medication treatment. Early diagnosis of COPD should be strengthened and the level of standardized treatment for patients should be improved.
