Objectives: To assess adherence to screening recommendations for the prevention of neonatal sepsis, and describe the prevalence of colonization by Group B streptococcus (GBS) as well as the perinatal outcomes associated with colonization by this bacterium.
Material and methods: Retrospective cohort study that included pregnant women at term and their newborns, seen at a private high-complexity clinic in Bogota, between July 1 and December 31, 2019. Adherence to screening and intrapartum antibiotic prophylaxis in pregnant women colonized with group B streptococcus, as well as the prevalence of colonization and early adverse perinatal outcomes were assessed.
Results: Overall, 1928 women were included. Adherence to screening was 68.0 % (95 % CI: 66-70.1) and 87.9 % to intrapartum antibiotic administration (95 % CI: 87.8-88); non-indicated use of antibiotics occurred in 14.7 % of the women, for 86.3 % final adherence to antibiotic prophylaxis. The prevalence of GBS colonization was 12.5 % (95 % CI: 10.7-14.3); the incidence of neonatal hospitalization was 27.5 % (95 % CI: 16.3-33.7). There were no cases of mortality or early neonatal sepsis attributable to screening status, colonization or prophylactic antibiotics for GBS.
Conclusions: Additional studies in other centers are required in order to determine adherence to this guideline, particularly in those that receive users affiliated to the subsidized regime which covers the most vulnerable population. Also, new population studies of GBS prevalence and cost-effectiveness of universal screening compared to risk factor-based antibiotic prophylaxis are needed.
