Outcomes Associated With Tiotropium Use in Patients With Chronic Obstructive Pulmonary Disease.

The article presents a cohort study which evaluates the effectiveness of regimens containing tiotropium bromide in patients with chronic obstructive pulmonary disease (COPD). The study observed two separate groups of patients with a diagnosis of COPD in the U.S. Veterans Affairs health care system. Results of the study indicate that the use of tiotropium, with inhaled corticosteroids (ICS) and long-acting β-agonists (LABA), was associated with reduced risk of mortality in COPD patients.
