Acinetobacter baumannii (Ab) is a nosocomial, multiresistent pathogen, affecting especially critically ill patients, leading to mortality; is unknown its impact in our hospital. Objectives: this study pretends to determinate infection incidence of Ab and its risk factors associated. Methods: it was performed an observational, case and control study, in 257 children admitted to Manuel Ascencio Villarroel Children Hospital; we found 4 spreads in a year, the incidence was 7,8/100 of admitted patients. Ab was isolated in environmental cultures, but was not found in personal cultures. Results: we found following risk factors after 10 days exposure: PICU days internship (OR=10,09; p=0,000), mechanical ventilation (OR=15,75; p=0,000), endothacheal tube (OR=17,09; p=0,000), urinary catheter (OR=11,9; p=0,000), central venous catheter (OR=12,9; p=0,000), peripherical venous catheter (OR=14,2; p=0,000), oro or nasogastric catheter (OR=13; p=0,000); mortality found associated to Ab was similar to the found in the control group Conclusions: we concluded that Ab is the most frequent pathogen isolated in our PICU, prolonged stay and invasive methods increase risk to be infected by this pathogen; control measures are necessary to decrease its incidence.

Keywords : Acinetobacter baumannii; incidence; risk factors; mechanical ventilation; PICU stay.
