Study design: Observational Study
Abstract: This is the first study to evaluate statin medication adherence and associated outcomes in a diabetic population based on a national Medicaid database.A retrospective claims-based study was conducted in patients who were continuously enrolled in Medicaid from January 2004 to December 2006.Patients (≥ 18 years) with diagnosis of hyperlipidemia and type 2 diabetes were identified by international classification of disease 9th revision (ICD-9) codes based on medical claims.Prescriptions of statin or oral antidiabetic medications were identified by national drug code (NDC) based on drug claims.Demographic, clinical and medication related information was extracted from the MarketScan ® Medicaid database.The eligible patients starting the use of statin medications in 2005 were followed for one year to measure medication use, hospitalization, outpatient visits, emergency room (ER) visits, and healthcare costs.A conceptual model based on modified health belief model and health services use behavior model was proposed in this study.Propensity scores were used to remove the imbalance of baseline characteristics between patients with diabetes and without diabetes.Regression models were used to compare mediation adherence and healthcare costs.Multiple linear regression analysis was implemented to assess associations between healthcare costs and statin medication possession ratio (MPR) , while logistic regression
