Details and patient eligibility

About

The national COPD screening program is in a cross-sectional manner at the baseline, planning to recruit a total of 800,000 participants from 160 districts or counties (5,000 for each site on average) from 31 provinces, autonomous regions or municipalities directly under the central government of China. The filtered COPD high-risk population and confirmed COPD patients will be managed and followed up according to the standardized clinical guidelines. The major aims of the program are to estimate the prevalences of COPD high-risk population and under- or miss- diagnosed COPD patients, and to manage the development and outcomes of the disease.
