In 2017, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) substantially changed its ABCD group categorization. Although several studies had been conducted to assess the impact of the new GOLD category, there was no research on the change in the GOLD classification in Vietnam. This retrospective analysis was conducted at the Asthma and Chronic Obstructive Pulmonary Disease (COPD) Clinic at the University Medical Center in Ho Chi Minh City, Vietnam. Our study population comprised patients visiting the medical center from January 2018 to January 2020. We categorized patients’ demographics, clinical characteristics, and pharmacotherapy based on GOLD 2011 and 2017 guidelines. A comparison between the two versions was also determined. A total of 457 patients were included in this study. The percentage of groups A, B, C, and D according to GOLD 2011 was 5%, 20.8%, 13.1%, and 61.1%, respectively, and according to GOLD 2017, it was 6.1%, 34.1%, 12%, and 47.8%, respectively. In terms of gender, male patients constituted nearly 95% of the study’s population (433/457 patients). Regarding pharmacotherapy, approximately 20% of the low-risk group (groups A and B) was overtreated with inhaled corticosteroid (ICS) components: long-acting β-agonists (LABA) + ICS (15.8%) and long-acting muscarinic antagonist + LABA + ICS (3.8%). There were 13.3% and 1.1% of patients transferred from D to B and from C to A, respectively. All of them had a lower predicted percentage of forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and FEV1/FVC than the patients who remained in groups B or A (p<0.005). This is the first research in Vietnam to show the distribution of COPD patients using both the GOLD 2011 and GOLD 2017 criteria. 14% of patients were reclassified from high-risk to low-risk groups when changing from the 2011 version to the 2017 one, and there was discordance of medications between guidelines and real-life practice. Therefore, clinicians should use their clinical competence to consider patients’ conditions before deciding on the appropriate therapeutic approach. Consequently, further studies were required to evaluate the effect of the change in the GOLD classification.
