Our aims were to determine the incidence of bacteraemia in a cohort of neonatal patients over a 14 year period, to describe the organisms involved, and to establish the rates of sepsis with regard to both early onset sepsis (EOS) and late onset sepsis (LOS). Lastly, we investigated the trends of neonatal sepsis, to determine whether changes in clinical practice influenced the rate of blood culture positivity. With regards to EOS, GBS was the predominant pathogen, followed by E.coli, CoNS, and S. aureus . The overall mean EO rate per 1000 live births (LBs) was 1.19. Looking at LOS, S. aureus , CoNS , Enterococcus spp. were the most common bacteria cultured. The mean LOS rate was 1.88 per 1000 live births. The overall rate of EOS remained fairly steady. GBS remains the major pathogen in EOS; however its incidence has remained largely unchanged over time in relation to both EOS and LOS. Conversely the rate of LOS peaked from ’05-’09, mainly due to an increase in Staphylococcus aureus , CoNS and Enterococcus spp. cases, and then improved dramatically in the following years. This was likely due to a change in hospital policies in relation to hand hygiene and intravenous line placement and maintenance.
