Initial attention has focused on mortality rates as a measure of quality. Since the Medicare mortality rates were first released in 1986 [1], increasingly numerous and various parties have compiled actual and expected hospital mortality rates to motivate improvements in quality and to compare hospitals. The federal government, state governments, peer review organizations, private insurers, and hospital associations have been among those producing such assessments. Lately, large employers have also become interested in assessing hospital quality [2]. Concerned about the value they receive for dollars invested in employee health benefit packages, companies are ...References1. U.S. Health Care Financing Administration.
