Abstract

Background: Intensive efforts to control nosocomial MRSA remain controversial. We report a decline in MRSA blood stream and other clinical isolates from our ICU in the absence of specific interventions against MRSA. Methods: Retrospective time series analysis of Staphylococcus aureus (SA) isolates from the Royal Melbourne Hospital ICU 2000-2007. Clinical isolates were electronically extracted from the microbiology database. Screening swabs and duplicate isolates collected within 7d from sterile and 30d from non-sterile sites respectively were excluded. Results: Consecutive 6 monthly MRSA (& total SA) clinical isolates/1000 occupied ICU bed days and MRSA (& total SA) blood culture isolates (unadjusted for occupancy) from 2000-2007 is presented in table 1. Trauma, cardiothoracic & other surgical comprised 63% (mean) of ICU admissions/ year. No MRSA specific interventions i.e. active screening, decolonisation or isolation were implemented. Interventions included antibiotic stewardship incorporating a computerized program (Jan 2001), regular rounds by infectious diseases physicians (April 2004), temporary screening & barrier nursing of Acinetobacter colonised patients during an outbreak of non-multiresistant Acinetobacter (Nov 2004-Dec 2005) and hand hygiene education (May 2005). Conclusions: Sustained reduction of endemic MRSA was achieved by quality improvement measures and limited infection control interventions. Intensive and expensive control measures may not always be necessary.
