Maternal sepsis causes significant morbidity and mortality, but little is known about outcomes of patients who recover from antepartum sepsis. This study evaluates perinatal outcomes of patients with sepsis who were discharged prior to delivery. We performed a retrospective cohort study of patients who delivered at our institution from 8/1/2012 to 8/1/2018 and had a prior antepartum admission for sepsis with subsequent discharge prior to delivery. Multifetal pregnancies, major fetal structural or genetic anomalies, TORCH infections, and patients who delivered during their antepartum admission were excluded. Primary outcomes were composites of obstetric and neonatal complications. Between group differences were assessed by Fisher’s exact test or t-test. 70 of 15,055 patients (0.5%) had an antepartum admission for sepsis. 59 of 70 patients (84%) were discharged without delivery. Of these, 8% were admitted to the intensive care unit (ICU), overall mortality was 1.7%, and median days from hospital discharge to delivery was 79 (IQR 34–141). Patients with sepsis were more often Black (22% vs 6%, p < 0.001), more likely to have pregestational diabetes mellitus (9% vs 2%, p = 0.003), and younger (30.6 vs 33.1 years, p < 0.001) than patients without sepsis. There were no differences in composite neonatal complications between the groups (25% vs 28%, p = 0.77). Patients with sepsis had higher rates of obstetric complications (49% vs 34%, p = 0.02), cesarean delivery (39% vs 25%, p = 0.02), postpartum hemorrhage (24% vs 14%, p = 0.04), and hypertensive disease of pregnancy (24% vs 11%, p = 0.006) than patients without sepsis. In subgroup analyses, severe sepsis defined by ICU admission was associated with earlier gestational age at delivery (36.1 vs 38.9 weeks, p = 0.01) and a trend towards more neonatal complications (60% vs 28%, p = 0.14). Patients that recover from sepsis during the antepartum period may have higher rates of adverse perinatal outcomes. Close surveillance for obstetric and neonatal complications is warranted in these patients.View Large Image Figure ViewerDownload Hi-res image Download (PPT)
