WhyNotTheBest.org was created and is maintained by The Commonwealth Fund, a private foundation working toward a high performance health system. It is a free resource for health care professionals interested in tracking performance on various measures of health care quality. It enables organizations to compare their performance against that of peer organizations, against a range of benchmarks, and over time. Case studies and improvement tools spotlight successful improvement strategies of the nation’s top performers.

Currently, the site includes measures of hospital quality that are publicly reported on the Centers for Medicare and Medicaid Services Web site, Hospital Compare. We will update these data sets four times a year. Data are included for nearly all U.S. hospitals, over 4,500. It also includes data on the incidence of central line associated bloodstream infections, from some 900 hospitals across the nation. For information on the particular measures, please see Methodology.

We will continue to add new measure sets and develop additional functionality over time. If you would like to provide feedback on the site or make a suggestion for improvement, please contact wntb@cmwf.org. If you are having technical problems with the site, please contact wntb-support@ipro.us.
