Abstract

Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) update2023 proposed new definitions of chronic obstructive pulmonary disease (COPD)and COPD exacerbation. However, an agreement on the definitions has not been made,either internationally or domestically. This study aimed to reach an agreement betweenexperts on the new definitions of COPD and COPD exacerbation in South Korea. Methods: A modified Delphi method was used to make an agreement on the definitionsof COPD and COPD exacerbation proposed by the GOLD update 2023. We performedtwo rounds of the survey including 15 Korean experts on COPD, asthma, andtuberculosis. Results: More than two-thirds of the experts agreed on 12 of the 13 statements relatedto the definitions of COPD and COPD exacerbation in the two rounds of the survey. The experts agreed on the definitions of COPD and COPD exacerbation that should berevised in line with the definitions proposed by the GOLD update 2023. However, theexperts showed an uncertain opinion on the statement that the definition of COPD includespatients with persistent airflow obstruction due to bronchiectasis. Conclusion: Based on this Delphi survey, experts’ agreement was made on the definitionsof COPD and COPD exacerbation proposed by the GOLD update 2023.
