Editorial: Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 Guidelines for COPD, Including COVID-19, Climate Change, and Air Pollution

The 2023 Global Initiative for Chronic Obstructive Lung Disease (GOLD) report includes relevant topics from the clinician’s perspective and evidence published on chronic obstructive pulmonary disease (COPD) since GOLD 2017. The World Health Organization (WHO) and GOLD 2023 have developed an updated definition of COPD as, “a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea, cough, expectoration, exacerbations) due to abnormalities of the airway (bronchitis, bronchiolitis) and/or alveoli (emphysema) that cause persistent, often progressive, airflow obstruction.” GOLD 2023 includes recommendations for COPD patients diagnosed with COVID-19 and acknowledges the role of reduced air quality in the etiology and progression of COPD. In May 2023, the GOLD Scientific Committee on Air Pollution and COPD reported that air pollution increasingly contributes to the pathogenesis of COPD. This Editorial aims to introduce the updated GOLD 2023 report in the context of climate change and the aftermath of the COVID-19 pandemic.
