Look out later this month for new features enabling users to compare hospital groups and regional data, and to more easily explore performance variation via an interactive U.S. map, on The Commonwealth Fund's performance benchmarking site, WhyNotTheBest.org. Updated data on the CMS process-of-care and patient experience measures also will be available soon, as will the latest data on the incidence of central-line bloodstream infections in hospitals across the nation. Register on WhyNotTheBest.org to receive alerts when new data or functionality are added.
