abstract = {Background: In 2017, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) proposed new classification criteria for patients with chronic obstructive pulmonary disease (COPD), which categorizes them into groups A–D based on risk of exacerbations and symptoms. The impact of the 2017 revisions on categorization and subsequent drug selection has been insufficiently studied in China.
Methods: This observational, multicenter, cross-sectional study recruited patients attending the outpatient clinics of 12 tertiary hospitals in China between April 2016 and July 2018. Patients were classified according to the GOLD 2014 and 2017 classification criteria and profiled based on categorization, demographics, clinical characteristics, and treatment regimens.
Results: In total, 1,278 COPD patients [mean age (±SD), 62.4±8.4 years; body mass index (BMI), 22.3±3.4 kg/m2] were included. According to the GOLD 2014 and 2017 classification criteria, the distribution in groups A–D was 58 (4.5%), 288 (22.5%), 28 (2.2%), 904 (70.7%) and 71 (5.6%), 573 (44.8%), 15 (1.2%), 619 (48.4%), respectively. Overall, 32% of patients in groups C–D were reclassified to groups A–B. Based on both GOLD 2014 and 2017, low BMI and education level were independent risk factors for high risk of exacerbation (i.e., being in groups C–D) (P},
