In July 2021, in response to high rates of severe maternal morbidity (SMM) due to severe hypertension in pregnancy, the Hawaii Perinatal Collaborative, in partnership with the Healthcare Association of Hawaii (HAH), began implementation of the AIM Severe Hypertension in Pregnancy Patient Safety Bundle in 10 of the state’s 12 birthing facilities. Between July 2021 and September 2022, in participating facilities, the percentage of pregnant and postpartum people with persistent severe hypertension who were treated within one hour increased from 46.3% to 63.9%, an increase of 38%. HAH continues to assist facilities with quarterly reporting of data, learning opportunities, and quality improvement support.
