Methods Respiratory specialists from 42 hospitals in Chongqing were investigated through questionnaire survey. The questionnaire contains two parts. The first part contains nine questions about the knowledge of 2011 GOLD new COPD classification system and its clinical use. The second part contains six questions about the reasons of failing to clinical use of the COPD classification system.
Results A total of 204 valid questionnaires were recovered. More than 90% respiratory specialists had understood the new COPD classification system with different degree, and believed it is suitable for clinical use. More than twothirds respiratory specialists knew well the ways about CAT and mMRC, but only 24% specialists were using these ways. The main reasons of failing to clinical use were as follows: 60% specialists believed the pulmonary function test can evaluate the COPD classification, and 66. 7% specialists were limited by short visit time. The cognition degree and clinical use of the new COPD classification systemin the specialists from third grade A class hospitals was better than those from the other hospitals. But the difference was not significant among specialists with different professional title.
