Neonatal early-onset sepsis calculator safety in an Australian tertiary perinatal centre.

Abstract

To determine if any cases of culture-positive neonatal early-onset sepsis (EOS) would be missed using the neonatal EOS calculator, when compared with current guidelines and practices. Retrospective audit of all neonates born at ≥35 weeks and admitted to Royal Brisbane and Women's Hospital with EOS from January 2014 to December 2020. A missed case was defined as antibiotic therapy not being recommended within 24 h of birth. Management recommendations according to the neonatal EOS calculator were compared with current guidelines and current practices. There were significantly more missed cases using the neonatal EOS calculator compared to the current guideline and current management groups. Using the neonatal EOS calculator, 11 neonates (35%, 95% confidence interval 19.2-54.6%) would not have received antibiotics by 24 h of age. In comparison, only one neonate (3%, 95% confidence interval 0.1-16.7%) would not have received antibiotics by 24 h of age using the current guidelines. In terms of the current practice in the cohort of patients, two neonates (6%) did not receive antibiotics by 24 h of age. The significantly higher rate of missed cases using the neonatal EOS calculator compared with current guidelines and practice supports the concerns many neonatologists have regarding safety of the neonatal EOS calculator.
