Abstract

The American health care system is plagued by high costs and poor public health outcomes, due in part to the overuse of costly diagnostic tests and treatments. In 2009, the Institute of Medicine estimated that unnecessary care wastes $750 billion, equivalent to about 30 percent of health care spending. Moreover, overtreatment can directly harm patients as a result of surgical complications, drug toxicity, and hospital-acquired infections. Yet while the problem of medical waste has long been recognized, solving the problem has proven elusive. In part, this difficulty is due to perverse economic incentives for physicians and hospitals, which still primarily receive reimbursement on a fee-for-service basis. Providers are financially motivated under this system to generate a higher volume of invasive procedures independent of their likely benefits. Patients generally lack the information needed to decline unnecessary services, even when they wish to actively share in medical decision-making, and a strong cultural bias pushes both patients and physicians to “do more,” even when evidence suggests that doing more may result in harm. In the 1990s, managed health care organizations attempted to rein in health care waste by stringently reviewing and prospectively denying payment for unnecessary tests and treatments, but that experiment was a political failure. Similarly, attempts to reduce overuse by shifting financial risk directly onto providers through capitated payment mechanisms have had limited success. The ability of these mechanisms to limit waste is compromised by the real or perceived incentive to also reduce spending on appropriate care. We propose a new conception of medical necessity that will reduce inappropriate care by allowing informed consumers to actively participate in decisions about their medical care. Where evidence-based guidelines are available, medical necessity should be determined on the basis of an objective, multi-level Matrix of Appropriateness rather than the subjective binary decision of an insurance company’s medical reviewer. Such Matrices have already been created by systematically combining published evidence with expert judgment to create clinically detailed, evidence based, multilevel medical necessity ratings for elective procedures based on individual patient characteristics. In our proposed system, if a patient desires a service proposed by a physician under clinical circumstances that receive low medical necessity ratings, the third-party payer would offer to cover the service but at a sliding co-payment scale imposing greater patient cost sharing based on the service’s appropriateness. This system would preserve patient choice while discouraging the overuse of costly treatments that provide little marginal value, reducing medical waste and improving the overall value of medical care.
