In 2017, preeclampsia/eclampsia was the most common cause of death during pregnancy and up to 42 days postpartum in Missouri. Missouri AIM began implementation of AIM’s Severe Hypertension in Pregnancy patient safety bundle in 36 of the state’s 62 birthing facilities in November 2019. Among the 29 birthing facilities who reported data, treatment of persistent severe hypertension within 60 minutes of episode onset increased from a median of 62% at baseline (November 2019 through January 2020) to a median of 87% post-intervention (July 2020 through December 2021). During the same period, the percentage of participating facilities who established processes for scheduling postpartum follow-up appointments for people with diagnoses of hypertension, preeclampsia, or eclampsia increased from 0% to 31%. Missouri AIM continues to support birthing facilities whose implementation of the Severe Hypertension in Pregnancy patient safety bundle was halted or stalled during the COVID-19 pandemic and provides technical assistance to address health disparities related to hypertension in pregnancy and postpartum.
