Background: Group B streptococcal disease is the leading cause of neonatal sepsis in the United States. We assessed predictors of compliance with the consensus guidelines for perinatal group B streptococcus disease prevention at two Group Health Cooperative hospitals.
Methods: A descriptive and cohort analysis was conducted of failure to comply with the screening-based approach to group B streptococcus prevention among singleton birth pregnancies in two Group Health Cooperative hospitals, September 1, 1996 to December 31, 1997. We studied determinants of failure to screen pregnant women for group B streptococcus at 35 to 37 weeks' gestation and failure to deliver intrapartum antibiotic prophylaxis to Group B streptococcus-positive women.
Results: Nearly 28 percent of 1969 women delivering at two Group Health Cooperative hospitals were not screened appropriately for group B streptococcus. Women who were not screened properly were more likely to be in their teens. A short length of hospital stay before delivery was the strongest predictor of the lack of administration of intrapartum antibiotic prophylaxis to infected multiparas at delivery. Group B streptococcus-positive women without pregnancy complications were less likely to receive intrapartum antibiotic prophylaxis than infected women with complications.
Conclusions: The findings of this study suggest that to improve group B streptococcus disease prevention, screening efforts should focus on teenage women, and intrapartum antibiotic prophylaxis delivery efforts should be aimed at low-risk women with precipitous labor.
