Between 2013 and 2015, complications related to hypertension and cardiovascular disease were the leading causes of pregnancy-related death in Mississippi. In response, the Mississippi Perinatal Quality Collaborative (MSPQC) began implementation of AIM’s Severe Hypertension in Pregnancy patient safety bundle in October 2019 and recruited 37 of the state’s 41 birthing facilities to participate. Between Q4 2019 and Q1 2022, the percentage of obstetric physicians and midwives who received education on severe hypertension and preeclampsia increased from 48% to 89%, and the percentage of obstetric nurses who received similar education increased from 62% to 93%. During the same time, the percentage of participating birthing facilities that had established unit policies and procedures to respond to hypertensive emergencies increased from 24% to 88%. The MSPQC continues to work with participating facilities on patient safety bundle implementation through quarterly leadership calls and other educational opportunities.
