Adverse Delivery and Neonatal Outcomes Among Women with Severe Maternal Morbidity in Illinois, 2018–2019

Objective: To examine adverse delivery outcomes from 2018 to 2019 severe maternal morbidity (SMM) cases that were reviewed by facility-level review committees in Illinois ( n = 666) and describe the burden of adverse delivery outcomes among demographic subgroups, SMM etiology, and whether the SMM event was potentially preventable. Materials and Methods: This is a descriptive analysis of the SMM review cohort. Consistent with expert recommendations to identify SMM for hospital quality review, SMM was defined as any intensive care or critical care unit admission and/or transfusion of four or more units of packed red blood cells from conception to 42 days postpartum. Adverse delivery outcomes were fetal death, low birthweight, preterm birth, neonatal intensive care unit admission, and 5-minute Apgar score
