Background: Bloodstream infections are common among patients in the neonatal intensive care unit (NICU). Here we show the frequency of the microroganisms found in the blood of patients in the NICU belonging to a national network in Colombia.
Methods: A country network with 27 public and private tertiary hospitals from 3 cities was stablished. Laboratory information was transferred monthly to a central data base and compiled by the use of Whonet software (WHO, ver 5.4). Bloodstream infections were selected from those patients in the NICU.
Results: Between 2001 and 2007 (june), a yearly average of 689 bloodstream infections were detected among patients in the NICU. 60% to 70% of the isolates were Gram-positive, while near 30% were Gram-negative bacilli. In the figure, the annual percentage of the microorganisms more commonly isolated is shown. Of interest, 84% of the coagulase negative Staphylococci (CNS) were resistant to oxacillin and between 6.9% and 10.8% of E. coli isolates had a phenotype that suggested the presence of extended spectrum b-lactamases (ESBL). Such phenotype was more frequently found in K. pneumoniae (41.1% to 51.1%). Candida albicans was the most frequently found yeast.
Discusion: Although oxacillin-resistant CNS predominated among bloodstream isolates, a high prevalence of Gram-negative bacilli was found, with a frequent expresion of ESBL. Fungal infections are not uncommon. Higher effords in infection control and antibiotic use should be made in order to diminished the number of resistant infections in high risk neonates.
