BackgroundChronic obstructive pulmonary disease (COPD) is a debilitating disease and places a large financial burden on health-care systems and society. We prospectively evaluated the cost-effectiveness offluticasone propionate (FP) treatment in patients with moderate-to-severe COPD, who were symptomatic on regular bronchodilator therapy.MethodsAn economic analysis was performed in a 6-month, randomized, double-blind clinical trial comparing FP 1,000 microg/day with placebo in 281 patients aged 45-79 years with symptomatic moderate-to-severe COPD. Data on clinical efficacy, health-care resource use and productivity loss associated with the management of COPD were prospectively collected. The main outcome measures were the incremental cost-effectiveness of achieving a > or = 10% improvement in FEV1 and of remaining exacerbation-free throughout the study. The economic evaluation was costed from the perspective of the NHS (direct costs) and of society (direct and indirect costs).ResultsFP was significantly more effective than placebo in terms of the proportions of patients demonstrating a > or = 10% improvement in FEV1 (32 vs. 19%; P = 0.02) and remaining free of moderate/severe exacerbations (75 vs. 63%; P = 0.02). The difference between the groups in total costs was not significantly different. Incremental cost-effectiveness analyses showed that the additional clinical benefits of FP relativeto placebo, in terms of a > or = 10% improvement in FEV1 or an increased number of patients free of moderate/severe exacerbations, were achieved at minimal additional costs from an NHS perspective (additional 0.25 pounds per day for bath) or at a net saving from a societal perspective. Sensitivity analysis showed that these results were robust to changes in the underlying assumptions.ConclusionsTreatment with FP was associated with statistically significant clinical benefits in patients with moderate-to-severe COPD currently symptomatic on regular bronchodilator therapy. As the differences in direct and total costs compared with placebo were small and non-significant, this treatment can be considered cost-effective in this patient population.
