A retrospective review of administrative claims data was conducted to identify health plan members with asthma who were persistent with their controller medications and those who were not persistent. Utilization of health care services and associated costs were measured for both groups. Non-persistent use of controller medications resulted in more asthma-related emergency department visits and home health services whereas persistent controller use was associated with more physician office and outpatient visits. Mean asthma-related medical costs per member were greater in the non-persistent cohort ($577.62) than in the persistent cohort ($323.03). These findings support the need for targeted interventions to address non-persistence in a managed Medicaid population.(Drug Benefit Trends. 2009;21:112-118)
