[A survey on the application of diagnostic and evaluation tools for chronic obstructive pulmonary disease among respiratory physicians].

Objective: To investigate the current status of the application of diagnostic and assessment tools for chronic obstructive pulmonary disease(COPD) by respiratory physicians in China. Method: An on-line questionnaire was designed to address the common questions in COPD diagnosis and evaluation, and this survey was conducted through Wechat. Result: A total of 3 204 valid questionnaires were collected. 71.7% of the physicians were from tertiary hospitals. 75.4% of the physicians diagnosed COPD strictly on the basis of lung function results after inhaled bronchodilators, and this percentage was higher in tertiary hospitals than in secondary hospitals(78.71% vs. 66.92%, P<0.01). 99.3% of the physicians evaluated symptoms of dyspnea, but 26.8% of physicians did not use a scoring system(CAT or mMRC) for quantitative assessment. Although 83.8% of physicians would use the guideline-recommended comprehensive assessment(ABCD classification), only 45.1% of them chose initial therapy exactly according to the classification. In addition, 28.3% of physicians did not routinely order blood eosinophil counts and 20.1% did not inquire the history of tuberculosis. Conclusions: Although most respiratory physicians followed the guidelines in the diagnosis and evaluation of COPD, the use of assessment tools was inadequate, which should be addressed in educational programs for COPD management.
