A 12-bed ICU experienced an outbreak of multiresistant Acinetobacter baumannii (MRA) from October 2009 to May 2010. A multifaceted strategy involving segregation, enhanced infection control procedures, and microbiological surveillance was implemented. We evaluated its impact on antibiotic stewardship.
A retrospective review of patient notes and results using AcuBase® was conducted: 90 consecutive patients before the outbreak (January to June 2008) and 91 thereafter (October 2010 to May 2011). Data included patient profiles, admission criteria, ICU survival, antimicrobials used, antibiotic days, number of patients on antibiotics, prescribing cost and the demographic of microbes isolated.
The need for a complex strategy to manage and eradicate an MRA outbreak in the ICU led to a clinically significant decrease in antibiotic use and prescribing cost saving following eradication of MRA. Improved antibiotic stewardship is achievable through better infection control strategies.
