Infants born prematurely have a greater likelihood of experiencing complications and health issues. One such issue is early-onset sepsis (EOS)—a serious and potentially fatal infection of the blood and/or cerebrospinal fluid occurring within the first three days after birth. Delivery characteristics – including mode of delivery, presence of labor, and rupture of membranes (ROM) duration prior to delivery – are all thought to contribute to EOS risk. However, a framework was lacking to understand the association of these combinations of delivery characteristics with EOS incidence in preterm infants.
Study design & findings
Deliveries of 2,937 pre-term infants were categorized by delivery mode, presence of labor, and duration of ROM. Then, the researchers analyzed EOS occurrence across groups to further understand which subsets of pre-term infants had the highest EOS incidence. A total of 21 (0.7%) of infants studied had EOS, and the majority were born in the setting of prolonged ROM (≥18 hours).
These data suggest that certain delivery circumstances are associated with higher rates of EOS in pre-term infants. Validation of these findings in a larger cohort may help better direct resources, inform deployment of preventive measures, and help reduce unnecessary antibiotic exposure for those at a lower risk for infection.
