Towards an expanded definition of value.

Abstract

Much of the change being sought in the United State's health-care system is predicated on improving value. Value is most simply defined as quality divided by cost, and physicians increasingly rely on the quality-adjusted life year as the numerical measure to justify their services. However, there are many other definitions of value being advocated by various stakeholders in the health-care reform effort. Incentive programs and pilot studies implemented by private and public payers are steering much of the current change. Expanding our understanding of how value is defined by health-care economists and policy makers can help spine providers navigate the evolving health-care landscape.
