Maternal morbidity and mortality remains a major public health concern, particularly among pregnant people of color. This US hospital established a multi-disciplinary committee, the obstetric Quality and Peer Review Committee (OBQPRC), to review all cases of severe maternal morbidity (SMM). This article compares the pre- and post-intervention periods to determine if rates of potentially preventable SMM decreased. While there was no difference in SMM rates pre- and post-intervention, the rate of potentially preventable events significantly decreased after implementation of routine review of all SMM.
