STUDY OBJECTIVE: To assess the lipid-lowering efficacy, safety, and costs of a large-scale statin formulary conversion program. DESIGN: Prospective, observational study. SETTING: Tertiary academic medical center. PATIENTS: A total of 980 patients consented to participate; 942 patients completed the study. INTERVENTION: Patients were converted from their current statin therapy to either cerivastatin 0.4 or 0.8 mg/day, or simvastatin 80 mg/day, using a conversion algorithm. MEASUREMENTS AND MAIN RESULTS: Efficacy and safety were evaluated at baseline and after 6 weeks of therapy; costs were also measured. Overall attainment of the National Cholesterol Education Program (NCEP) goal for low-density lipoprotein cholesterol (LDL) increased from 64.8% to 74.5% of patients (p<0.001); mean LDL decreased from 115+/-30 mg/dl to 106+/-25 mg/dl (p<0.001). Adverse events occurred in 3% of patients, and included myositis (0.6%) and increased hepatic transaminases (0.1%). Overall costs were reduced by $115/patient treatment-year. CONCLUSION: Statin therapeutic interchange can improve lipid control at reduced costs. The possibility of uncommon but potentially serious adverse effects suggests that these programs require appropriate monitoring.
