The effects of long-acting bronchodilators on total mortality in patients with stable chronic obstructive pulmonary disease
Background:
Chronic obstructive pulmonary disease (COPD) is the 4th leading cause of mortality worldwide. Long-acting bronchodilators are considered first line therapies for patients with COPD but their effects on mortality are not well known. We performed a comprehensive systematic review and meta-analysis to evaluate the effects of long-acting bronchodilators on total mortality in stable COPD.
Methods
Using MEDLINE, EMBASE and Cochrane Systematic Review databases, we identified high quality randomized controlled trials of tiotropium, formoterol, salmeterol, formoterol/budesonide or salmeterol/fluticasone in COPD that had a follow-up of 6 months or longer and reported on total mortality. Two reviewers independently abstracted data from the original trials and disagreements were resolved by iteration and consensus.
Results
Twenty-seven trials that included 30,495 patients were included in the review. Relative risk (RR) for total mortality was calculated for each of the study and pooled together using a random-effects model. The combination of inhaled corticosteroid (ICS) and long-acting beta-2 agonist (LABA) therapy was associated with reduced total mortality compared with placebo (RR, 0.80; p = 0.005). Neither tiotropium (RR, 1.08; p = 0.61) nor LABA by itself (RR, 0.90; p = 0.21) was associated with mortality.
Conclusions
A combination of ICS and LABA reduced mortality by approximately 20%. Neither tiotropium nor LABA by itself modifies all-cause mortality in COPD.Medicine, Department ofPharmaceutical Sciences, Faculty ofRespiratory Medicine, Division ofNon UBCMedicine, Faculty ofReviewedFacult
