AIMS: To examine the clinical and economic outcomes associated with the use of long-acting bronchodilators for initial maintenance treatment of chronic obstructive pulmonary disease (COPD) by analyzing health insurance claims data in the US. METHODS: A retrospective, observational, matched cohort study used health insurance claims data (January 2008 to June 2013) to assess COPD-related outcomes for subjects aged ≥40 years. Subjects were assigned to a study cohort according to the first observed prescription fill for a long-acting bronchodilator (fluticasone propionate 250 mcg/salmeterol 50 mcg [FSC] or tiotropium bromide 18 mcg [TIO]). The analysis period for each subject comprised a 1-year pre-index date and 1-year post-index date. Primary outcome measure was total COPD-related costs per-patient per-year (PPPY) during the follow-up period. Secondary outcome measures included COPD-related exacerbations and the components of COPD-related costs. RESULTS: Overall, 24,040 subjects were identified; the analysis sample consisted of 19,090 subjects (9,545 per cohort) with no significant differences between cohorts. Mean COPD-related total costs PPPY were numerically lower among the FSC cohort; however, the difference was not statistically significant ($2,224 [±4,108] vs $2,352 [±3,721], p = .057). There was no difference between cohorts for COPD-related medical costs (p = .894). COPD-related pharmacy costs were significantly, yet modestly, lower in the FSC cohort compared with the TIO cohort ($1,160 [±1,106] vs 1,275 [±1,110], p < .001). There were no statistically significant differences in the rate or number of exacerbations between the matched cohorts. LIMITATIONS: While propensity scoring achieved balance in baseline characteristics, some residual confounding unobserved in the database may be present. CONCLUSIONS: Few clinical and economic differences between subjects initiating maintenance therapy with FSC or TIO were observed.
