Validity of COPD diagnoses reported through nationwide health insurance systems in the People's Republic of China.

ABSTRACT:

Background

COPD is the fourth leading cause of death worldwide, with particularly high rates in the People's Republic of China, even among never smokers.

Methods

During 7 years of follow-up, 11,800 COPD cases were identified by linkage with mortality registries and the national health insurance system. We randomly selected ~10% of the reported COPD
