COPD guidelines, including the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, offer evidence-based recommendations on optimal medication use [4]. However, many COPD patients do not receive these medications [5–7]. Previous studies have described appropriate use of long-acting inhaled medications in the COPD population and others have trended medication use over time [8, 9]. However, none that we are aware of, have described or quantified trends in guideline recommended long-acting inhaled medications over time in a large, complete, real world COPD population. This was the focus of the current descriptive study.FootnotesThis manuscript has recently been accepted for publication in the ERJ Open Research.
