Costs of providing antiplatelet medication for percutaneous coronary intervention patients

Academic Article


  • Objectives: To propose a model in which insurers work with hospitals to provide a discharge supply of antiplatelet medication to patients receiving stents and to examine the cost implications of this strategy. Study Design: A decision tree was modeled using data from previously published research. The study adopts an insurer's perspective. Methods: Data on patient delays in filling antiplatelet prescriptions and rates of associated adverse events were taken from published research. The costs of adverse events (death or acute myocardial infarction [AMI]) are taken from Healthcare Cost and Utilization Project estimates of hospital costs for diagnosis-related groups associated with AMI. Results: In the base case, expected costs totaled $1782 when stent implantation patients were provided with a discharge supply of medication and $1857 under the current standard of care, a difference of $75. Insurers can supply up to 60 days of medication without increasing total costs. The strategy of offering a discharge supply of medication is cost saving under a range of estimated rehospitalization costs and medication costs. However, this result is dependent on the ability of a discharge supply of medication to reduce rates of death or AMI. Conclusions: Providing discharge supplies of antiplatelet medication resulted in lower overall costs for insurers in most of the cases modeled.
