Extract
The population burden of COPD remains high well into the 21st century, although with great regional variability [1]. Changes in the geographical and secular distribution of COPD points to the interaction of a number of risk factors beyond tobacco and other forms of smoking, which is still considered the first and foremost causal risk factor of COPD. We read with interest the new Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 document, proposing a new taxonomy of COPD and suggesting six etiotypes on the origin of COPD [2]. This taxonomy is based on work found elsewhere [3, 4]. To the best of our knowledge, these etiotypes are not evidence-based, and the information required to obtain them has not been explored. We aimed to identify the information required to determine the classification of COPD etiotypes by GOLD 2023, by means of panel discussion and consensus by the authors.
