Abstract：
:The current debate on our healthcare system has focused primarily on the cost of care. Because of drastically rising costs and their burden on our economy, government and the private sector have developed many approaches to reduce these costs. Managed care, special contracting arrangements, and government fiat have all been used to stem the tide of rising costs--with variable success. We propose that the primary goal of healthcare is the provision of patient benefit, and we describe a model that calculates an expected benefit in terms of survival and quality of life. We have applied this model to a cohort of patients undergoing coronary angiography to determine the distributions of benefit. Furthermore, we describe a reimbursement strategy that relates the expected therapeutic benefit to the reimbursement received for that therapy--the greater the benefit, the greater the reimbursement. The future of our healthcare system lies in keeping the patient at the center of the debate on the delicate balance between optimal care and societal cost.
