Hospital-onset cases of MRSA, a staph infection resistant to the antibiotic methicillin, decreased 54% in the U.S. between 2005 and 2011, according to a study reported Sept. 16 in JAMA Internal Medicine. Cases involving healthcare-associated community-onset decreased 28% over the period, while community-associated cases decreased only 5%.
The large decrease in hospital-onset infections “is highly encouraging and may be attributable to increased awareness and implementation of local and nationwide infection prevention measures in many health care settings, including those targeting intravascular catheter-related infections and health care transmission of multidrug-resistant organisms,” the authors said. “…Significant progress in preventing invasive MRSA infections in the dialysis and post-discharge settings is needed to substantially reduce the overall burden of invasive MRSA infections.”
In related news, CDC also released a report aimed at increasing awareness of the threat that antibiotic resistance poses to the treatment of bacterial infections, and what states, communities, health care providers and others can do to combat antibiotic resistance.
