All together, these hospital-acquired infections cost the U.S. health care system an estimated $3.5 billion per year.

"We had a great opportunity to study the effect of private rooms on infection acquisition rates because we could compare two close-by university hospitals -- less than a mile apart -- that serve the same area," she told Reuters Health in an e-mail.
In total, the hospitals recorded 6,597 bacteria, yeast and fungi infections over the 5-year period.
For the three bacteria that were at the focus of infection control -- methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus species (VRE) and Clostridium difficile -- the combined risk of a patient acquiring an infection fell by 54 percent after the transition to private rooms, taking into account the infection rate at the comparison hospital.
