The national COPD screening programme in China: rationale and design

Background COPD is the most prevalent chronic respiratory disease in China. It is estimated that there is a large, as-yet undetected, high-risk population who will develop in COPD in future. Methods and design In this context, a nationwide COPD screening programme was launched on 9 October 2021. This multistage sequential screening programme incorporates a previously validated questionnaire (i.e. COPD Screening Questionnaire) and pre- and post-bronchodilator spirometry to target the COPD high-risk population. The programme plans to recruit 800 000 participants (eligible age 35–75 years) from 160 districts or counties of 31 provinces, autonomous regions or municipalities across China. The filtered COPD high-risk population and early-detected COPD patients will receive integrated management and be followed-up for ≥1 year. Discussion This is the first large-scale prospective study to determine the net benefit of mass screening for COPD in China. Whether the smoking cessation rate, morbidity, mortality and health status of individuals at high risk of COPD could be improved along with this systematic screening programme will be observed and validated. Moreover, the diagnostic accuracy, cost-effectiveness and superiority of the screening programme will also be assessed and discussed. The programme marks a remarkable achievement in the management of chronic respiratory disease in China. The national COPD screening programme is the first large-scale prospective study to determine the net benefit of mass screening for COPD in China. The programme aims for remarkable achievements in management of chronic respiratory disease in China. https://bit.ly/3Hi475g
