Epidemiology and risk factors for colonization and infection by Acinetobacter baumannii in an ICU in Tunisia, where this pathogen is endemic

摘要: Because Acinetobacter baumannii has become an alarming endemic pathogen in our country we decided to conduct this prospective study, from January 2004 December 2005, order determine risk factors and outcomes involved clinical colonization or infection by A. a 16-bed Tunisian intensive care unit (ICU). One hundred two isolates were obtained 63 patients, with rate of 45%. The multidrug-resistant (MDR) was 39% during the 2-year epidemic outbreak October 2004. This followed closure all ICU rooms selective intestinal decontamination polymyxin. During 12-month post-intervention program (January–December 2005), declined. analysis for spread showed that only Simplified Acute Physiological Score (SAPS II) involved. On other hand, no factor identified multidrug resistance patients either colonized infected baumannii. There statistically significant difference crude mortality (67.5% MDR vs 46.7% susceptible baumannii; P = 0.04).
