Fewer COPD Exacerbations and Pneumonia Hospitalizations with LABA-LAMA Inhalers Compared to ICS-LABA in COPD

Dr. Coursen Clinical question: Is a long-acting beta agonist and long-acting muscarinic antagonist (LABA-LAMA) inhaler combination better than an inhaled corticosteroid and long-acting beta agonist (ICS-LABA) combination to improve clinical outcomes in patients with chronic obstructive pulmonary disease (COPD)? Background: Clinical guidelines recommend LABA-LAMA over ICS-LABA in COPD patients but randomized clinical trials have shown mixed data on clinical outcomes comparing these maintenance combination inhalers. Study design: Large retrospective cohort study Setting: National insurance database Synopsis: From a national insurance database, 30,216 pairs of COPD patients were identified as starting maintenance combination inhalers with either LABA-LAMA or ICS-LABA. Those with a prior diagnosis of asthma were excluded. LABA-LAMA showed improved clinical outcomes compared to ICS-LABA with a 20% reduction in first pneumonia hospitalization and an 8% reduction in moderate or severe COPD exacerbation. No difference was found in patients with higher eosinophil counts. Limitations included only one year of follow-up time. These results were overall consistent with findings from the 2016 FLAME trial. Bottom line: A large retrospective cohort study demonstrated fewer COPD exacerbations and pneumonia hospitalizations for COPD patients initiated on LABA-LAMA as opposed to ICS-LABA for new start of maintenance combination inhalers.
