COPD 2024: Applying the Canadian Thoracic Society (CTS) 2023 Chronic Obstructive Pulmonary Disease (COPD) Guideline for Preventing Exacerbations, Improving Health Status, and Preventing Mortality

Chronic Obstructive Pulmonary Disease (COPD) is a common, chronic respiratory condition that is associated with the risk of morbidity and mortality. Approximately 2 million Canadians live with COPD, and as many as 1 million suffer while remaining undiagnosed and untreated. COPD exacerbations represent the most expensive cause of hospitalization with the highest likelihood of hospital readmission. Exacerbations are the primary driver of mortality in patients with COPD. These exacerbations are the second leading cause of hospitalization in Canada with an average length of stay of 7 days. In fact, 1 in 5 patients with COPD will die within 1 year of their first hospitalization due to an exacerbation. For those 65 or older in Ontario, the overall 365-day mortality stands at nearly 28% following their first hospitalization due to an exacerbation. The best indicator of the risk of future exacerbations is a history of exacerbations. The time has come to end the stepwise pharmacologic escalation that has defined the treatment paradigm in COPD. The call to action is to shift from the slow promotion of inhaled pharmacotherapy based on exacerbations to a direct escalation to inhaled pharmacotherapy with demonstrated evidence to prevent the exacerbations.
