Resumen

BRAUN J, Stephanie et al. Risk factors associated to vancomycin-resistant enterococccus colonization in the Army Hospital in Santiago . Rev. chil. infectol. [online]. 2009, vol.26, n.4, pp.374-375. ISSN 0716-1018.  http://dx.doi.org/10.4067/S0716-10182009000500014.

Since the appearance of Vancomicin-resistant enterococci (VRE) in our country, the Chilean Ministry of Health recommended the surveillance of intestinal colonization in patients in critical wards. We report the results of surveillance in ICU and onco-hematological wards from 2002 to 2008, with analysis of possible risk factors: demographical data, use and type of antibiotic, days of hospitalization prior to sampling, and year of hospitaliza-tion. Colonization rate increased from 0.03 cases per lOOObed-days in2003 to 0.18 cases during2008. Univariate analysis identified 7 risk factors associated with ERV colonization: hospitalization in ICU, use of antibiotics, use of 3 or more compounds, use of imipenem or colistin, > 10 days of hospitalization prior to the study and year of hospitalization ( before 2007 or after). Multivariate analysis by logistic binary regression showed that only the last two: >10 days of hospitalization prior to the study and year of hospitalization (before 2007 or after), were significantly associated to colonization by ERV.

Palabras clave : Risk factors; vancomycin-resistant Enterococcus; intestinal colonization.
