About 1 in 25 hospitalized patients in the United States has an infection related to their hospital stay, according to new data from the Centers for Disease Control and Prevention that highlight the need for continued efforts to prevent such infections.
In 2011, an estimated 648,000 patients had at least one infection they aquired in a hospital, resulting in about 722,000 hospital-related infections for that year, according to a new report. On any given day, 4 percent of hospitalized patients had at least one hospital-related infection, and as many as 1 in 9 died from their infection, the report found.
The most common infections acquired in hospitals were pneumonia (about 22 percent of all infections), surgical site infections after an operation (22 percent), gastrointestinal infections (17 percent) and urinary tract infections (13 percent), according to the report, published today (March 26) in the New England Journal of Medicine.

The most common microbes that caused these infections were the bacteria Clostridium difficile (12 percent of infections), the bacteria Staphylococcus aureus (11 percent) and the bacteria Klebsiella (10 percent).
Still, some progress has been made in preventing such health care-associated infections in recent years, according to a second CDC report, also released today.
