Prevalence of Acinetobacter baumannii carriage in patients of 53 French intensive care units on a given day

Objective. - This study was made to evaluate multiresistant Acinetobacter baumannii colonization in French intensive care units. Design. - We conducted a prevalence study on the carriage of A. baumannii for a one-day period in various French ICUs. On December 10, 2003, one nasal and/or rectal swab sampling was performed in 506 patients of 53 ICUs. Results. - Sixteen patients (3.16%) from 7 centers (13%) were colonized by A. baumannii. None of the known risk factors for colonization by multiresistant A. baumannii were identified in these patients. Conclusions. - Overall, A. baumannii colonization is limited except during epidemic situations. Our study reflects the carriage of A. baumannii in ICUs on a given day. This study showed that there was no multiresistant A. baumannii epidemic clone, potentially responsible for outbreaks, present in the tested French ICUs. (c) 2007 Elsevier Masson SAS.
