Material-method: 333 physicians who completed the questionnaire were included in this cross-sectional questionnaire study. The questionnaire contained demographic data, professional information, extent of guideline use, rationales behind using or not using a guideline. The data was compared with the same survey conducted previously in 2011 and was analyzed by appropriate statistical methods. Results: 80 physicians were resident pulmonologists (24%), 250 physicians were specialists (75.1%). 298 (89.5%) physicians reported that they follow at least one guideline for selection of the appropriate treatment in COPD. The current application of guidelines when compared with the first survey in 2011, was found to be decreased, 91.2% and 89.5%, respectively (p = 0.07). 46.8% (n = 156) of participants thought that guidelines provided the physicians more legal protection (p < 0.001). The number of physicians who didn't follow the guidelines due to workload increased over this period of time (36.8% in 2011, 85.3% in 2018, p < 0.001). The number of physicians using inhaler steroid combinations as their first choice of treatment was found to be similar with the previous survey (p = 0.909). Conclusion: According to the results of previous questionnaire, the application of COPD guidelines has decreased. The number of pulmonologists who declared they have no time for following or applying guidelines has profoundly increased since 2011. Despite the warnings of these guidelines, the use of inhaler steroid combination as a first treatment option in COPD is still common.
