MDR Infection Risk Rises With Each Hospital Day

Extended stays in hospital appeared to increase the risk of infection with a multidrug-resistant Gram-negative pathogen, researchers said.

In a single-center study, the risk of such infection rose by 1% for every day in hospital, according to Tonya Smith, PharmD, of the University of Utah.
