Community-acquired MRSA could skew your numbers

As if there wasn’t enough to impede the prevention of healthcare-acquired MRSA (HA-MRSA), it seems that community-acquired MRSA (CA-MRSA) could have a significant effect on current and future prevention efforts.

Researchers from the Medical University of South Carolina in Charleston, SC, presented data at the 36th International APIC Meeting in Fort Lauderdale, FL, which showed the impact of USA 300 CA-MRSA on the healthcare facility over a four-year period.

The researchers looked at data from patients who developed MRSA at the facility from January 2004 to June 2008, according to Pediatric Supersite [1]. Of the 377 cases of HA-MRSA recorded, 101 were bloodstream infections, 165 were surgical site infections and 50 were pneumonia; the rest were classified asĀ  “other.”

After analyzing the infections, researchers determined that USA 300 CA-MRSA may have been responsible for as many as 24.1% of HA-MRSA infections. More importantly numbers indicated that CA-MRSA increased “significantly” from the beginning of the study to the end.

Furthermore the percentage of surgical site infections caused by USA 300 CA-MRSA was higher compared to all other types of HA-MRSA (31% vs. 20.8%).

If you’d like more information about how to prevent and control MRSA infections in your facility, read about the Infection Prevention Core Training Bundle [2]. The bundle consists of an infection prevention handbook and a series of Webcasts, the first of which deals specifically with MDROs.
