Abstract

OBJECTIVE:

To determine (a) the proportion of asymptomatic infants born at ≥35 weeks gestation evaluated for early-onset sepsis (EOS) and exposed to postnatal antibiotics; (b) reasons for and outcomes of the evaluations, and (c) anticipated changes when applying the Centers for Disease Control and Prevention (CDC) 2010 guidelines to this study population.

STUDY DESIGN:

Retrospective cohort study of infants born at ≥35 weeks gestation in 2008-2009 in a large maternity center.

RESULT:

Out of the 7226 infants that met the study criteria: 1062 (14.7%) were evaluated for EOS and half of those evaluated, received empiric antibiotics. 70.4% of evaluations were performed owing to maternal intrapartum fever, but 23% were prompted by inadequate Group B Streptococcus (GBS) prophylaxis alone. Three cases of blood culture-proven infection were identified.

CONCLUSION:

Improved approaches are needed to identify asymptomatic infants who are at risk for EOS to decrease unnecessary evaluations and antibiotic exposure. Transition to the 2010 CDC GBS guidelines may eliminate a quarter of EOS evaluations among these infants.
