  1. Colonization with antibiotic-resistant Gram-negative organisms in a pediatric intensive care unit.

    Article - En anglais


    To measure the prevalence of colonization with antibiotic-resistant Gram-negative organisms and its association with potential risk factors, including antibiotic exposure, in a pediatric intensive care unit (ICU).


    Prospective, observational study.


    A 16-bed tertiary care pediatric ICU.


    All children admitted to the pediatric ICU for>24 hrs over a 5-month period.

    Measurements and Main Results 

    Two hundred ninety-six patients, approximately half of all patients admitted to the ICU, were enrolled in the study ; 236 patients had sufficient data collected for analysis and were prospectively examined for nasopharyngeal and gastrointestinal colonization by antibiotic-resistant Gram-negative organisms (ceftazidime minimal inhibitory concentration of>16 mug/mL, or tobramycin minimal inhibitory concentration>8 mug/mL).

    Association between colonization and potential predisposing factors including demographics, diagnosis, Pediatric Risk of Mortality (PRISM) score, invasive instrumentation, and prior ICU antibiotic exposure was assessed.

    More than 20% of patients were found to be colonized with an antibiotic-resistant Gram-negative organism.

    Examination of the timing of colonization indicated that more than half were identified within 72 hrs of admission. (...)
