    Abstract:
    OBJECTIVES: To evaluate the performance of the early-onset sepsis (EOS) risk calculator in a cohort of neonates born to mothers with clinical chorioamnionitis, and to compare the diagnostic utility of the EOS calculator, clinical signs, and laboratory evaluations for correctly identifying EOS in this cohort. STUDY DESIGN: This was a retrospective study of neonates born at ≥35 weeks of gestation to mothers with chorioamnionitis. The risk and management categories for all neonates were calculated using the EOS calculator, and these results were analyzed and compared with laboratory data and clinical signs. RESULTS: Of the 1159 neonates born to mothers with chorioamnionitis, 5 (0.43%) had culture-proven EOS. Data for calculation of EOS risk were available for 896 neonates, including the 5 neonates with culture-proven EOS. The management recommendation based on the calculator was no empiric antibiotic treatment for 67% of the neonates, including 2 of the 5 with EOS. All neonates with culture-proven EOS had abnormal complete blood counts and C-reactive protein levels at 6-12 hours. Three of the 5 neonates with EOS had clinical signs of sepsis. CONCLUSIONS: The risk of EOS in neonates born to mothers with chorioamnionitis is low. The use of an EOS calculator may reduce the use of empiric antibiotics in chorioamnionitis-exposed neonates, but in our cohort, some neonates with culture-confirmed EOS would have been missed. A larger study is needed to evaluate whether limiting antibiotics to chorioamnionitis-exposed neonates with clinical and/or laboratory signs of infection can safely decrease antibiotic use.
