Is group C really needed as a separate group from D in COPD? A single-center cross-sectional study

OpenAlex İngilizce

INTRODUCTION: GOLD 2017 report proposed that the combined COPD assessment should be done according only to symptom burden and exacerbation history in the previous year. OBJECTIVE: This study aims to investigate the change in the COPD groups after the GOLD 2017 revision and also to discuss the evaluation of group C and D as a single group after the GOLD 2019 report. METHOD: The study was designed as a cross-sectional. 251 stable COPD patients admitted to our out-patient clinic; aged ...40 years, at least one-year diagnosis of COPD and ...10 pack-year smoking history were consecutively recruited for the study. RESULTS: values of group A and B patients were significantly low and group C and D patients had had exacerbations in more frequently the previous year in GOLD 2017 compared to GOLD 2011. CONCLUSION: After the GOLD 2017 revision, the rate of group C patients decreased even more compared to GOLD 2011 and the group C and D may be considered as a single group in terms of the treatment recommendations with the GOLD 2019 revision. We think that future prospective studies are needed to support this suggestion.
