The Commonwealth Fund’s landmark www.WhyNotTheBest.org website now includes information on the incidence of central-line-associated bloodstream infections (CLABSIs) in intensive care units in hospitals nationwide. These preventable infections occur when catheters are placed in large veins to speed administration of fluids. Experts estimate a mortality rate of between 12% and 25% for each infection, of which there are an estimated 25,000 cases annually in the U.S. The hospital-specific data on the WhyNotTheBest site are made available under arrangement between The Commonwealth Fund, Consumer Reports Health and the Leapfrog Group. Data are arrayed by standardized infection rates as defined by the Centers for Disease Control and Prevention and measured against national rates. While 10 states require reporting under state law, voluntary reporting is now taking place in another 34 states. All programming of the website was undertaken by IPRO’s e-Services Department.
