Objective: To understand the situation of respiratory rehabilitation and oxygen inhalation therapy in chronic obstructive pulmonary disease (COPD) patients aged 40 years or older in China, and provide basic information for the development of pulmonary rehabilitation. Methods: The data were from 2014-2015 COPD surveillance in China. Chinese residents aged 40 years or older were recruited through a complex multi-stage stratified cluster sampling from 125 COPD surveillance points in 31 provinces (autonomous regions, municipalities). Standardized face to face electronic questionnaires were used to collect information about respiratory rehabilitation and oxygen inhalation therapy of the patients. Spirometry was performed on all participants, and patients with post- bronchodilator FEV(1)/FVC<70% were diagnosed with COPD. The number of defined COPD patients was 9 134. Based on the complex sampling design, the respiratory rehabilitation treatment rate and oxygen inhalation therapy rate of COPD patients aged 40 years old or older in China were estimated, and the influencing factors were analyzed. Results: A total of 9 118 COPD patients aged 40 years or older were included in the analysis. The rate of respiratory rehabilitation was 0.8% (95 CI : 0.6%-1.0%), and the rate of oxygen inhalation therapy was 2.5% (95 %CI : 2.0%-2.9%). Among patients with severe symptoms or high risk of acute exacerbation (combined COPD assessment groups B, C, D), the rate of respiratory rehabilitation was 1.4% (95 %CI : 0.9%-1.9%), and the rate of oxygen inhalation therapy was 5.4% (95 %CI : 4.4%-6.4%). Multivariate logistic regression analysis showed that urban or rural residences, geographic area, awareness of COPD, history of acute exacerbation and severity of airflow restriction had influences on the respiratory rehabilitation rate in the COPD patients. Gender, geographic area, awareness of COPD, history of acute exacerbation, mMRC scores and severity of airflow restriction had influences on the patients' oxygen inhalation therapy rate. Conclusions: The rate of respiratory rehabilitation and oxygen inhalation therapy in COPD patients aged 40 years or older was relatively low in China. It is necessary to explore an effective model of pulmonary rehabilitation and COPD management, so that more COPD patients may have access to scientific pulmonary rehabilitation treatment.
