Abstract:

Objective

To investigate the current status of diagnosis of chronic obstructive pulmonary disease (COPD) among residents aged 40 years old and above in Shijingshan District, Beijing.

Methods

Random sampling method was used to conduct questionnaire survey, body measurement, and lung function test among residents aged 40 and above in 10 communities in Shijingshan District, Beijing, and statistical analysis was performed on the obtained data.

Results

A total of 4096 participants were finally included in the study, of whom 416 were diagnosed with COPD. The prevalence rate of COPD was 10.2% (9.2%~11.1%). Among the COPD population, only 59 cases had been diagnosed previously, with a diagnostic rate of 14.2% (11.1%~17.8%), and as high as 85.8% (82.2%~88.9%) of COPD patients had not been diagnosed before. Most of the missed COPD patients had no respiratory symptoms [35.6% (30.7%~40.6%)] or mild symptoms [56.3% (51.1%~61.4%)], had never heard of COPD [63.3% (58.2%~68.2%)], and were in the early stage of COPD [ 51.8% (46.6%~57.0) in GOLD 1 and 41.2% (36.2%~46.3%) in GOLD 2]. Undiagnosed COPD is related to never doing lung function [OR=22.82 (6.53~79.70)], never heard of chronic obstructive pulmonary disease [OR=9.21 (3.24~26.16)], no respiratory symptoms [OR=3.90 (1.11~13.73)], and slight respiratory symptoms [OR=2.88 (1.11~7.51)].

Conclusion

COPD is a common disease among residents of Shijingshan, Beijing, with a high prevalence rate, but a low diagnostic rate and a high rate of missed diagnosis. There is an urgent need to improve the awareness of COPD among community residents, and the identification ability and diagnostic rate of COPD by community doctors.
