title: Risk factors for and impact of methicillin-resistant Staphylococcus aureus nasal colonization in patients in a medical intensive care unit.
abstract: This retrospective cohort study investigated the impact and predictive factors of methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization in 180 patients admitted to a medical intensive care unit between July 2009 and June 2010. No significant associations between MRSA nasal colonization and the incidence of health care-associated multidrug-resistant-related infections, intensive care unit length of stay, or inpatient mortality were found. Significant risk factors for MRSA colonization included previous medical history of diabetes mellitus and congestive heart failure.
