ABSTRACT
To investigate physicians' knowledge about chronic obstructive pulmonary disease (COPD) in tertiary hospitals in northeast China.Physicians from 77 tertiary hospitals in northeast China were surveyed with a questionnaire,which included questions such as risk factors,symptoms,exacerbations,comorbidities and diagnostic criteria of COPD.Besides cigarette smoking,air pollution and pulmonary infections,only 22.5% (40/178) physicians recognized that the biomass fuels may induce COPD.Totally 59.0% (105/178) physicians recognized the importance of spirometry to the diagnosis of COPD.Besides dyspnea,cough,sputum production,wheezing and chest tightness,only 23.7% (42/177)of physicians considered that limitation of activity was an important symptom of COPD.65.5% (116/177)physicians believed that recurrent lung infections was one of the most important comorbidities of COPD.However,less than 30% [20.9% (37/177)-28.8% (51/177)] physicians were aware of the other important comorbidities.The physicians of tertiary hospitals in northeast China need to be systematically educated on COPD to meet the new guideline.
