Between 2014 and 2016, hypertensive disorders of pregnancy were among the leading causes of severe maternal morbidity and mortality in New Jersey. In January 2017, the New Jersey Perinatal Quality Collaborative (NJPQC) began implementing AIM’s Severe Hypertension in Pregnancy patient safety bundle in 36 of the state’s 48 birthing facilities. Between Q1 2018 and Q1 2019, treatment of persistent severe hypertension within 60 minutes of episode onset increased from 53.4% to 64.3% among the participating birthing facilities. During the same time, the percentage of participating facilities who reported having established unit policies and procedures to respond to hypertensive emergencies increased from 51.0% to 63.3%. The New Jersey Perinatal Quality Collaborative continues to work with its birthing facilities to fully implement the AIM Severe Hypertension in Pregnancy patient safety bundle through expanded education opportunities and other technical assistance opportunities.
