Why Not the Best?WhyNotTheBest.org includes process-of-care measures, patient satisfaction measures (from the Hospital Consumer Assessment of Healthcare Providers and Systems), readmission rates, mortality rates, and average reimbursement rates. All of these performance measures are publicly reported on the Centers for Medicare and Medicaid Services Web site, Hospital Compare, and include data from nearly all U.S. hospitals. WhyNotTheBest.org also includes data on the incidence of central line-associated bloodstream infections, from over 1,500 hospitals across the nation. It also includes measures assessing whether and to what extend hospitals have adopted electronic medical records (from the American Hospital Association survey), as well as measures of population health and utilization and costs, from the Institute of Medicine. Finally, the site includes performance data for a subset of the Agency for Healthcare Research and Quality Inpatient Quality Indicators (IQIs), Patient Safety Indicators (PSIs), and Prevention Quality Indicators (PQIs). Currently, we have such data for the majority of hospitals in 12 states. For further information on the particular measures, please see Methodology.
