Abstract

An observational study using pharmacy and medical claims was used to determine whether there are differences in asthma care cost between patients that are newly started on montelukast and low-dose fluticasone propionate. Patients were identified who had at least one ICD-9 (493.XX) claim for asthma and were newly prescribed inhaled fluticasone propionate 44 microg (FP) or montelukast 5 or 10 mg (MON). Subjects could not have had a claim for any inhaled corticosteroid or oral leukotriene modifier in 9 months prior to the first prescription claim for either FP or MON. They were subsequently followed for 9 months. Multi-variate regression analysis was used to determine the influence of these single-controller therapies on post-index asthma related costs. Positively skewed cost variables were log-transformed prior to their inclusion into the multi-variate model. Asthma-related costs were adjusted for age, gender, health plan, co-morbidities, pre-index asthma medication use and pre-index asthma care costs. Multivariate regression analysis, adjusting for baseline covariates, indicated that compared to treatment with montelukast, treatment with FP had significantly (P<0.001) lower post-index total asthma related costs. Adjusted least squares mean total asthma care costs for the 9-month post-index period were $US649 for FP 44 microg compared to $US1028 for montelukast
