ARTICLE HIGHLIGHTS
Research background
Globally, sepsis is the third leading cause of maternal mortality. China has relatively high rates of sepsis-related maternal morbidity and neonatal mortality. However, the risk factors for maternal sepsis in mainland China are not well-characterized.
Research motivation
We aimed to analyze the etiology of maternal sepsis and to identify the associated risk factors using the new definitions of sepsis and septic shock. The identified risk factors can be used to develop prediction models for early intervention.
Research objectives
To analyze the etiology of maternal sepsis and to identify the associated risk factors.
Research methods
Data of obstetric patients with infection who were admitted to the Third Affiliated Hospital of Guangzhou Medical University between January 2009 and June 2018 were retrospectively analyzed. Patients were divided into the sepsis group and non-sepsis group based on the definition of sepsis. Patient characteristics, obstetric factors and duration of hospitalization were compared between the two groups. Risk factors for maternal sepsis were identified using multivariate logistic regression models.
Research results
The morbidity rate of maternal sepsis was 9.76/10000; the fatality rate in the sepsis group was 11.6%. Mode of admission, poor prenatal care, labor induction, cervical cerclage and first trimester and second trimester pregnancy were risk factors for maternal sepsis. Escherichia coli was the most common causative organism for maternal sepsis; the uterus was the most common site of infection.
Research conclusions
This study determined the incidence and fatality rate of sepsis in pregnant women and identified the risk factors for sepsis in infected pregnant women.
Research perspectives
The identified risk factors can be used to establish prediction models for early intervention against maternal sepsis.
