Apr. 20, 2009 Healthcare Reform should start with "evidence-based reimbursement", structuring physician payment incentives around existing empirical evidence of clinical benefit, which would improve quality and reduce the cost of healthcare, says a commentary written by two cardiologists and published in Circulation: Cardiovascular Quality and Outcomes.
For example, some 500,000 U.S. patients suffering from mild chest pain due to coronary artery disease undergo balloon angioplasty or percutaneous coronary intervention (PCI) every year, a procedure that costs approximately $20,000 per patient, for a total U.S. expenditure of $10 billion a year. However, empirical studies document that 10 percent-20 percent of PCI patients are asymptomatic, only 50 percent have undergone a stress test to determine the severity of their disease and as many as 30 percent aren't taking prescription heart medications that, for patients with mild coronary artery disease, could be just as effective as PCI.
The authors cite a recent COURAGE (Clinical Outcomes Utilizing Revascularization and Aggressive drug Evaluation) trial which followed 2,000 patients with mild to moderate chronic stable angina. All patients received optimal medical therapy. Half of the patients also underwent angioplasty. The patients received follow-up care for 4.6 years, but there was no significant difference between the groups in the mortality rate.
As an example of Evidence-based Financial Incentives, the authors propose that physicians of the patients who undergo PCI be paid on a sliding scale, from $8,000 to $24,000, with the highest payments going to the physicians of patients with the most severe symptoms because the sickest patients receive the most benefit from the procedure.

"A lot of care isn't tied directly to proof of patient benefit in clinical trials," Diamond said. "It's not that the care is wrong. It's not documented to be of value. And if it's not documented to be of value, then it should be worth less. The purpose is not to deny anybody of healthcare, but rather to funnel them to the best proven care alternatives."
Diamond and Kaul suggest empirical data could be used to determine how much physicians would be paid by Medicare and private insurers for performing specific procedures. They hope to prompt a discussion of "evidence-based reimbursement incentives" rather than "pay for performance" among the public and policy makers. President Barack Obama has called for a national discussion of healthcare reform in the fall of 2009.
