INTRODUCTION: We estimated the cost-effectiveness of atorvastatin in the primary prevention of cardiovascular events in patients with type 2 diabetes using data from the Collaborative AtoRvastatin Diabetes Study (CARDS). METHODS: A total of 2838 patients aged 40-75 years with type 2 diabetes and no documented history of cardiovascular disease and without elevated low-density-lipoprotein cholesterol were recruited in the UK and in Ireland. Patients were randomly allocated to atorvastatin 10mg daily (n=1428) or placebo (n=1410) and were followed up for a median of 3.9 years. Direct treatment costs and effectiveness were analysed to provide estimates of cost per event avoided and cost per life-year gained over the trial period and over a patient's lifetime. RESULTS: The incremental cost-effectiveness ratio over the trial period was estimated to be Euro 3862 per clinical event avoided. Over the patient's lifetime, the incremental cost per life-year gained was Euro 2506 when considering cardiovascular deaths, and Euro 1418 per year when considering all-cause death. CONCLUSIONS: Primary prevention of cardiovascular disease with atorvastatin is cost-effective in patients with type 2 diabetes, with the incremental cost-effectiveness ratio for this intervention falling within the current acceptance threshold.
