Retrospective cohort study of neonatal early onset of sepsis and the role of the EOS calculator in a level II nursery.

Sepsis is a major cause of mortality and morbidity in neonates. With the improvement in health care 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. 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. 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 < 0.0001) could be achieved in this cohort. Sixty three percent of neonates who received IV antibiotics in this cohort were classified as 'clinically well' based on the EOS-calculator. 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 health care policies.

Neonatal early-onset sepsis calculator: Impact on antibiotic use in a level II neonatal unit in Western Australia.

Overuse of empirical intravenous antibiotics in neonates in high-income countries (HICs) is well documented. The Kaiser Permanente neonatal early-onset sepsis (EOS) calculator is an evidence-based sepsis risk assessment tool that has demonstrated potential to reduce antibiotic usage in this population. The incidence of early-onset sepsis in most HICs is 0.4-0.8 per 1000 live births. The objective was to evaluate the calculator's impact on antibiotic rates and length of stay in a regional level II Special Care Nursery. A single-centre retrospective cohort study compared antibiotic administration rates in the first 72 h in neonates ≥35 weeks gestation born during two 6-month periods in 2019 (pre-EOS calculator) and 2021 (post-EOS calculator). Electronic and paper case records were accessed to capture data. Continuous data were summarised using mean and standard deviation, and categorical data were summarized using frequency distributions. There were 951 (2019) and 1129 (2021) infants born during the study periods. Following implementation of the calculator, antibiotic exposure decreased from 13.7% to 4.7% of all neonates without reported negative outcomes. Mean length of stay for neonates born across the two periods decreased from 2.38 to 2.13 days. Indications for antibiotic use shifted more towards clinical condition and away from obstetric risk factors. There were no culture-proven cases of sepsis or readmissions with EOS in either period. Implementation of the EOS calculator significantly reduced exposure to antibiotics, without adverse outcomes.

Potential benefit from the implementation of the Kaiser Permanente neonatal early-onset sepsis calculator on clinical management of neonates with presumed sepsis.

To assess the potential benefit from the implementation of the Kaiser Permanente early-onset sepsis calculator (EOS-C), in terms of antibiotic use and requested laboratory tests, in a network of neonatal intensive care units (NICUs) in Greece, and to determine the incidence of early-onset sepsis (EOS) in Greek NICUs, a prospective surveillance study was conducted in 7 NICUs between April 2018 and June 2019. Data were collected for all newborns ≥ 34 weeks' gestation receiving empiric antibiotic therapy within the first 3 days of life. The number of live births and positive blood or cerebrospinal fluid cultures within the first 3 days of life were used for calculation of EOS incidence. Evaluation of possible impact of implementing the calculator was done by comparing the clinicians' recorded management to the calculator's suggested course of action. The unit-specific incidence of culture-proven EOS ranged between 0 and 2.99/1000 live births. The weighted incidence rate for all 7 units was 1.8/1000 live births. Management of EOS guided by the calculator could lead to a reduction of empiric antibiotic initiation up to 100% for the group of "well-appearing" neonates and 86% for "equivocal," lowering exposure to antibiotics by 4.2 and 3.8 days per neonate, respectively. Laboratory tests for blood cultures drawn could be reduced by up to 100% and 68%, respectively. Sensitivity of the EOS-C in identifying neonates with positive blood cultures was high.Conclusion: Management strategies based on the Kaiser Permanente neonatal sepsis calculator may significantly reduce antibiotic exposure, invasive diagnostic procedures, and hospitalizations in late preterm and term neonates. What is Known: • Neonates are frequently exposed to antibiotics for presumed EOS. • The Kaiser Permanente sepsis calculator can reduce antibiotic exposure in neonates.. What is New: • EOS calculator can be an effective antibiotic stewardship tool in a high prescribing country and can reduce invasive diagnostic procedures and mother-baby separation. • Incidence of EOS in Greece is higher compared to other European countries.
