Cost-effectiveness analysis of fluticasone versus montelukast in children with mild-to-moderate persistent asthma in the Pediatric Asthma Controller Trial.

Abstract

Cost-effectiveness analyses of asthma controller regimens for adults exist, but similar evaluations exclusively for children are few. We sought to compare the cost-effectiveness of 2 commonly used asthma controllers, fluticasone and montelukast, with data from the Pediatric Asthma Controller Trial. We compared the cost-effectiveness of low-dose fluticasone with that of montelukast in a randomized, controlled, multicenter clinical trial in children with mild-to-moderate persistent asthma. Analyses were also conducted on subgroups based on phenotypic factors. Effectiveness measures included (1) the number of asthma-control days, (2) the percentage of participants with an increase over baseline of FEV(1) of 12% or greater, and (3) the number of exacerbations avoided. Costs were analyzed from both a US health care payer's perspective and a societal perspective. For all cost-effectiveness measures studied, fluticasone cost less and was more effective than montelukast. For example, fluticasone treatment cost $430 less in mean direct cost (P < .01) and resulted in 40 more asthma-control days (P < .01) during the 48-week study period. Considering sampling uncertainty, fluticasone cost less and was more effective at least 95% of the time. For the high exhaled nitric oxide (eNO) phenotypic subgroup (eNO ≥25 ppb) and more responsive PC(20) subgroup (PC(20) <2 mg/mL), fluticasone was cost-effective compared with montelukast for all cost-effectiveness measures, whereas not all the effectiveness measures were statistically different for the other 2 phenotypic subgroups. For children with mild-to-moderate persistent asthma, low-dose fluticasone had lower cost and higher effectiveness compared with montelukast, especially in those with more airway inflammation, as indicated by increased levels of eNO and more responsivity to methacholine.
