In the 3 hospitals in the study, 144,904 deliveries occurred from January 1, 2007 to December 31, 2016. During this period, 102 maternal-neonate dyads met criteria and were included in the analysis. (Table 1) describes the maternal demographics and medical conditions. The mean gestational age at delivery was 38.4 weeks. There were 2 multiple gestations and approximately 10% of patients (10/102) attempted trial of labor after cesarean. Evaluating pregnancy complications, 22% of women had term or preterm premature rupture of membranes, 8% chorioamnionitis, 10% antenatal bleeding within 24 hours of delivery, and there was one vasa previa (Table 2 ). Prenatal diagnosis and ultrasound demonstrated growth restriction in 5% of pregnancies, suspected macrosomia in 3%, a major congenital anomaly in 6%, and a genetic abnormality in 5%.
