Nosocomial bacterial and fungal meningitis in children; an eight year national survey reporting 101 cases. Pediatric Nosocomial Meningitis Study Group.
One hundred and one cases of nosocomial meningitis in children from a national survey over 8 years have been analyzed for risk factors and outcome. From 101 cases, 115 organisms were isolated. Seventy six were Gram-positive bacteria, 29 were Gram-negative and there were ten fungal isolates. Major risk factors for acquisition of nosocomial meningitis were neurosurgery (70.2%), ventriculoperitoneal shunt (42.9%), prior therapy with broad spectrum antibiotics (64.1%), central venous catheter (94.5%), premature neonates with very low birth weight (32.8%) and total parenteral nutrition (68.8%). Overall attributable mortality was 14. 9%; in bacterial infection it was 13.2% and in fungal nosocomial meningitis, 30.0%. Higher mortality was significantly related to perinatal pathology with CNS abnormality, prematurity polymicrobial infection with Enterobacteriaceae and concomitant bacteraemia. Prematurity in neonates, very low birth weight and infection with Enterobacteriaceae were significantly associated with a worse outcome.
