Abstract

OBJECTIVE:

We sought to assess the efficacy of a clinical protocol to reduce the incidence of early-onset neonatal group B Streptococcus (GBS) infection.

STUDY DESIGN:

We assessed neonatal sepsis from GBS and other organisms with use of a before-after study design to evaluate the effects of implementation of combined intrapartum antimicrobial prophylaxis given selectively to mothers with GBS risks and penicillin G given to all neonates.

RESULTS:

In 1994, early-onset GBS infection developed in 31 of 13,887 live births (2.2/1000), 13 preterm and 18 term cases. After implementation of the prophylaxis protocol (1995), 6 of 13,527 live births had early-onset GBS (0.4/1000) (P <.001). There were no preterm (P =.0004) and 6 term GBS cases (P =.02). The efficacy continued through 1999 (0.5/1000) without an increase in neonatal infections from other bacteria.

CONCLUSION:

Combined maternal and infant antimicrobial prophylaxis can significantly and safely reduce rates of early-onset GBS infection in both preterm and term infants.
