Objective: To measure the effectiveness of managed care-led interventions in Medicaid subjects with asthma on medication adherence and acute hospitalization in Pennsylvania.

Methods: A total of 3589 members (age range, 5-64 years) served by two Pennsylvania-based Medicaid managed care plans (southeastern Pennsylvania [SEPA] and Lehigh-Capital/New West Pennsylvania [LCNWPA]) with low adherence rates (proportion of days covered [PDC]; 20%-67%) for asthma controller prescription fills in 2012 were guided through a care continuum by a comprehensive asthma strategy, consisting of adherence-improvement interventions (grouped as general intervention [GI] or personalized intervention [PI] for higher-risk subjects). Medication adherence and acute hospitalization rates (emergency department [ED] and inpatient [IP]) were compared at baseline versus one-year post-intervention using paired t-test or signed-rank tests.
