In 2018, cardiovascular concerns and conditions related to hypertension accounted for one-fourth of pregnancy-related deaths in Louisiana, and Black people were three times more likely to experience a pregnancy-related death compared to White people. In response, the Louisiana Perinatal Quality Collaborative (LaPQC) was established to address the state’s leading causes of morbidity and mortality, and in August 2018 LaPQC began implementation of AIM’s Severe Hypertension in Pregnancy patient safety bundle, eventually recruiting 43 of the state’s 49 birthing facilities. Between August 2018 and January 2022, the percentage of participating birthing facilities that had established unit policies and procedures to respond to hypertensive emergencies increased from 21% to 100%. The LaPQC continues to work with facilities to refine and improve identification of and response to severe hypertension, including assuring appropriate integration of treatment algorithms into emergency department settings.
