Background:
Experimental clinical studies have demonstrated that the addition of salmeterol to inhaled corticosteroids (ICSs) is superior to the addition of montelukast to ICSs. Observational research from real-world clinical practice is needed to confirm these results.
Objective:
The present study was designed to assess, in clinical practice, the comparative impact on health care utilization and cost of 2 dual-controller therapies, ICS + salmeterol and ICS + montelukast.
Methods:
This study involved the use of a 24-month pre/post retrospective design in patients continuously enrolled in any of 14 United HealthCare plans. Outcomes assessed were post-index pharmacy costs, rates of emergency department visits and hospitalizations, numbers of filled prescriptions for short-acting beta-agonists (SABAs), total asthma costs, and total health care costs.
Results:
Subjects in the ICS + salmeterol group had 35% fewer post-index SABA claims than subjects in the montelukast add-on group (P
Conclusion:
In comparison with the use of montelukast and ICS, the use of salmeterol and ICS was associated with a significant reduction in SABA use, decreased hospital event rates, and significantly lower total asthma care costs.
