Abstract
INTRODUCTION: Statins can reduce the risk of cardiovascular events in patients with diabetes. The objective of this analysis was to evaluate whether primary prevention with statin treatment is cost-effective for newly diagnosed type 2 diabetes mellitus (T2DM) patients in the Chinese context. METHODS: An economic analysis of primary prevention with statin treatment was conducted using the Chinese Outcomes Model for T2DM with a time horizon of a lifetime, which was developed and validated based on the Chinese population. Clinical costs and utility inputs were gathered from published sources. Lifetime discounted quality-adjusted life-years (QALYs), costs, and the incremental cost-effectiveness ratio (ICER) were measured. The uncertainty was evaluated by one-way and probabilistic sensitivity analyses. RESULTS: Statin treatment with atorvastatin 10 mg could add 0.08 QALYs with an additional $1676 compared with that of no statin management (control strategy) over a lifetime horizon, which led to an ICER of $21,924 per QALY gained. At a willingness-to-pay threshold of $27,351 per QALY gained, there was an approximately 80% probability of statin treatment being cost-effective compared with the control strategy. The model outcomes were most sensitive to the length of the expected life and age at the T2DM diagnosis. CONCLUSIONS: Statin treatment with atorvastatin is most likely cost-effective for primary prevention in Chinese patients newly diagnosed with type 2 diabetes. FUNDING: Partially funded by Pfizer Inc.
