A comparison of Triple I classification with neonatal early-onset sepsis calculator recommendations in neonates born to mothers with clinical chorioamnionitis.

Objective: To compare the early-onset sepsis (EOS) calculator recommendations for infants born to mothers with clinical chorioamnionitis with those made by the Triple I classification. Study

Design: Retrospective analysis of chorioamnionitis-exposed neonates ≥35 weeks. EOS risk was calculated with baseline risks of 0.5/1000 and 4/1000. Mothers were retrospectively categorized using the Triple I classification. Calculator recommendations were compared with the Triple I classification recommendations.

Results: We included 687 chorioamnionitis-exposed neonates. With a baseline risk of 0.5/1000, the calculator recommended no evaluation in 68.4% of infants of mothers with confirmed Triple I. With a baseline risk of 4/1000, 62.3% of infants of mothers with confirmed Triple I and 57.1% of infants born to mothers who did not meet fever criteria would have received evaluation.

Conclusions: The EOS calculator with either baseline risk does not recommend evaluation in a large number of infants born to mothers with confirmed Triple I.
