Users of WhyNotTheBest.org can search for and compare data from nearly 1,000 hospitals on the incidence of central line–associated bloodstream infections (CLABSIs)—one of the most lethal hospital-acquired complications. The updated data show wide variation in CLABSI incidence, despite strong evidence on how to prevent these infections. The data are available on WhyNotTheBest.org through a partnership among The Commonwealth Fund, The Leapfrog Group, and Consumers Union.
