Abstract

Asthma is a chronic disease whose effects are controlled/ prevented using appropriate medication. Although benefits of asthma medication is well known, poor medication adherence among asthma patients has been reported. Medication non-adherence is associated to increased healthcare costs, unnecessary hospital utilization, readmission and even death in few cases. The overarching goal of this research was to evaluate the impact of medication non-adherence on hospital admissions, and identify key factors that result in medication non-adherence for Medicaid insured asthma patients.

To achieve these objectives, Correlation analysis, T-tests, Multivariate logistic analysis and odds ratios were performed. Based on results of the study, the present study did not find significant relationships between control medication adherence and the different types of hospital visits (i.e. emergency department visits, inpatient admits, and readmission). However, patients with high rescue medication adherence had fewer emergency department visits (p-value=0.0004) and inpatient admissions (p-value=0.0303). Patients with more than 4 office visits had better rescue medication adherence, older and low-income patients had higher 30-day readmissions rate. While, male and low-income patients had emergency visits

Additionally, The two types of insurance coverage (Temporary Assistance for Needy Families and Supplemental Security Income-Non Dual) were the only significant predictors of control medication adherence among the factors analyzed (with p-values =0.0001). Asthma patients with TANF and SSI- Non Dual coverage are less adherent to control medication adherence compared to other coverage. Also, control and rescue medication adherence was not significantly different among case managed and non-case managed asthma patients.
