The pursuit of evidence-based medicine is now at the core of the agenda for improving health care in the United States. All major quality measurement systems use science-based indicators of proper processes of care, such as the ORYX measures of the Joint Commission on Accreditation of Healthcare Organizations,1 the Health Employer Data and Information Sets measures of the National Committee on Quality Assurance,2 the measures used by the Quality Improvement Organizations under contract with the Centers for Medicare & Medicaid Services,3 and at least 70 of the 179 measures in the 2004 National Health Care Quality Report from the Agency for Healthcare Research and Quality.4
