Neonatal bloodstream infections in a pediatric hospital in Vietnam: a cohort study

Septicemia and bloodstream infections (BSIs) are major causes of neonatal morbidity and mortality in developing countries. We prospectively recorded all positive blood cultures (BSI) among neonates admitted consecutively to a tertiary pediatric hospital in Vietnam during a 12-month period. Among 5763 neonates, 2202 blood cultures were performed, of which 399 were positive in 385 neonates. Among these, 64 died, 62 in relation to septicemia. Of the BSI isolates, 56% was known pathogenic and 48% was gram-negative bacteria, most frequently Klebsiella spp. (n = 78), Acinetobacter spp. (n = 58) and Escherichia coli (n = 21). Only three Streptococcus spp. were identified, none group B. Resistance against antibiotics applied was common. The mortality was highest in neonates with gram-negative BSI compared with no confirmed BSI and gram-positive BSI (P < 0.01). In this setting, the majority of BSI were likely to have been transmitted from the environment. Improvement of hygienic precautions and systematic BSI surveillance are recommended.
