Secondary prevention after PCI: the cost-effectiveness of statin therapy in the Netherlands
MetadataShow full item record
Background Little is known about the cost-effectiveness of secondary prevention after percutaneous coronary intervention (PCI). The aim of this study was to estimate the cost-effectiveness of statin therapy. Methods A cost-effectiveness analysis was performed using data from the Lescol Intervention Prevention Study (LIPS). In the LIPS trial, patients with normal-to-moderate hypercholesterolaemia who had undergone a first PCI were randomised to receive either fluvastatin 40 mg twice-daily plus dietary counselling or dietary counselling alone. A Markov model was used to estimate the incremental costs per quality-adjusted life year (QALY) and life year gained (LYG). Costs were based on prices and reimbursed charges, utility data were drawn from literature. Monte Carlo simulations and multivariate analysis were used to assess uncertainty. Results Routine statin treatment costs an additional ෳ4 (SD ම6) per patient over ten years compared with controls. It resulted in an additional 0.078 (0.047) QALYs or 0.082 (0.041) LYG. The incremental costs per QALY and LYG were 12 (,648) and ู54 (,617) respectively. Anticipating a willingness to pay of ರ,000 per QALY, there is a 75.1% chance that fluvastatin treatment is cost-effective. Conclusion Statin therapy with fluvastatin is economically efficient with regard to reducing heart disease in the Netherlands when given routinely to all patients following PCI.
