Community-Associated MRSA More Common in Smaller Hospitals

Smaller hospitals with healthier, but poorer, patients had a larger percentage of patients with community-associated methicillin-resistant Staphylococcus aureus, according to a study in Infection Control and Hospital Epidemiology.

Researchers analyzed clinical MRSA isolates from inpatients in 30 hospitals in Orange County, Calif., from October 2008 through April 2010. Community-associated MRSA strains accounted for 46 percent of all MRSA isolates. The community-associated strain was associated with smaller hospitals, hospitals with more Medicaid patients and hospitals with more patients with low comorbidity scores, according to the study.
