INTRODUCTION
Infection in the setting of cardiovascular surgery is not infrequent and associated with adverse outcomes and mortality. Multidrug resistant organism related infection cases have augmented in in this setting lately whereas in the other type of ICU’s. Acinetobacter baumannii (AB) is a gram-negative coccobasillus, which is a ubiquitous microorganism having ability to colonize and survive in diverse environments and improve diverse mechanisms of resistance, due to AB is difficult to control in hospitals. [1-6]. Particularly multidrug-resistant (MDR)-AB infections (isolate is non-susceptible to at least one agent in three or more antibiotic classes) associated with high mortality rates in intensive care units (ICUs) [3,6,7].
After an MDR-AB infection epidemic in our hospital at the end of 2009 we aimed to search the rate of multidrug-resistant acinetobacter baumannii infections in cardiovascular surgery intensive care unit (CS-ICU) and risk factors and independent outcome predictors retrospectively for 2 year time period.
