Abstract
Objective: To assess the cost-effectiveness of budesonide/formoterol (B/F)+tiotropium (TIO) versus placebo (PBO)+TIO for the treatment of chronic obstructive pulmonary disease (COPD) patients eligible for inhaled corticosteroid/ long-acting β2-agonist from societal and healthcare perspectives in Denmark, Finland, Norway and Sweden.
Method: The cost-effectiveness analysis was based on the 12-week, randomised, double-blind CLIMB trial (NCT00496470) of 659 COPD patients with pre-bronchodilator FEV1 ≤50%, and at least one severe exacerbation (hospitalisation, emergency room visit or systemic glucocorticosteroids) the preceding year. Subjects were treated with B/F 320/9µg bid+TIO 18µg qd or PBO bid+TIO 18µg qd. Effectiveness was defined as the number of exacerbations avoided. A sub-analysis included antibiotics in the definition of an exacerbation. Resource use from the trial was combined with 2010 Danish (DKK), Finnish (€), Norwegian (NOK) and Swedish (SEK) unit costs. The incremental cost-effectiveness ratios (ICERs) were estimated by bootstrapping.
Results: From a societal perspective, the ICER was estimated at €174 per exacerbation avoided (pEA) in Finland while B/F+TIO was dominant in the other countries. From a healthcare perspective, B/F+TIO was dominant in Norway and the ICERs were estimated at DKK 1,580 (€212), €307, SEK 1,573 (€165) pEA for Denmark, Finland and Sweden, respectively. Including antibiotics decreased ICERs by 8-15%. Sensitivity analyses showed that results were overall robust.
Conclusion: The results indicate that B/F+TIO represents a clinical and economic benefit to health systems and society for the treatment of COPD in the Nordic countries.
