Abstract
The pattern of neonatal bacterial infection, its management and the types of infection control policy were ascertained in 20 neonatal intensive care units (NICU) in Australia by questionnaire survey. Group B Streptococcus and Escherichia coli were the predominant organisms responsible for perinatally acquired infection for which the most common antibiotic combination used was Penicillin and Gentamicin. Staphylococcus epidermidis and aureus (majority Methicillin resistant) were the predominant organisms responsible for nosocomial infection for which the most common antibiotic combination used was Vancomycin and Cefotaxime. A Serratia epidemic was experienced in four NICU. Lumbar and suprapubic punctures were frequently done as part of the diagnostic workup in nosocomial infections but not with perinatally acquired infections. Haematological indices considered useful as a diagnosis aid varied between NICU and acute phase reactants were rarely relied upon for diagnosis or for monitoring treatment response. Granulocyte transfusion and intravenous immunoglobulins were infrequently used in therapy. No consensus was found on infection control policies. Eight NICU required routine gowning on entry, two restricted sibling visiting and four restricted visiting by relatives and friends. Although routine bacteriological surveillance on staff or equipment was uncommon, serial cultures were carried out in infants from the body surface in six NICU and from the endotracheal aspirate in 17 NICU. Antiseptics used with technical procedures included iodine, chlorhexidine and alcohol used singly or in combination. Skin and umbilical cord care also varied between NICU. The literature was reviewed to determine the effectiveness or otherwise of some of the existing policies in the prevention or management of neonatal infection to encourage consensus towards a more rational approach to neonatal infection in Australia.
