Retrospective Cohort Study of Neonatal Early Onset of Sepsis and the role of the EOS calculator in a level II Nursery
2021
Abstract Background Sepsis is a major cause of mortality and morbidity in neonates. With the improvement in healthcare standards, the incidence of neonatal Early Onset Sepsis (EOS) has reduced significantly. A recent Web-based EOS-calculator has been introduced with the aim to reduce the use of IV antibiotics in neonates. The role of the EOS-calculator has yet to be ascertained in this regional Special Care Nursery (SCN) in Western Australia. This study aims at examining the local incidence of culture proven EOS and the role of the EOS calculator. Method It is a retrospective study examining all newborns ≥35 weeks gestation throughout 2019 (Jan - Dec 2019) who received IV-antibiotics. The local incidence of culture-proven EOS was established and applied onto the EOS calculator. The recommended management by the EOS-calculator was cross-examined with the local EOS guideline. Overall proportion of reduction in IV antibiotics use was formulated. Other relevant laboratory data extracted was analysed with Pearson’s correlation test with the EOS scores. Results Total included sample was n = 252 with an annual birth of 1880s indicating 13.4% of all neonates born throughout year 2019 was treated with IV antibiotics. The local incidence of culture-proven EOS was 0.5/1000. By applying the EOS-calculator, a significant reduction of IV antibiotics usage from 13.4% to 3.9% (z value 10.4, p Conclusion The EOS-calculator could reduce the use of IV antibiotics in the neonatal population significantly in this regional SCN (from 13.4% to 3.9%). Judicial use of IV antibiotics is imperative as part of the holistic care for the neonates. Implementation of the EOS-calculator must be done strategically considering the local incidence of EOS and other healthcare policies.
