In June 2021, in response to high rates of severe maternal morbidity (SMM) due to hemorrhage, the Hawaii Perinatal Collaborative, in partnership with the Healthcare Association of Hawaii (HAH), began implementation of the AIM Obstetric Hemorrhage Patient Safety Bundle in 10 of the state’s 12 birthing facilities. Between April 2021 and June 2022, the proportion of patients who had their blood loss measured from birth through the recovery period using quantitative and cumulative techniques increased from 49.0% to 67.0%. Among participating birthing facilities, the rate of SMM among people who experienced an obstetric hemorrhage, excluding those who received blood transfusions alone, decreased from 9.0% in 2019 to 7.1% in 2021, a reduction of 21.1%. HAH continues to assist facilities with quarterly reporting of data, learning opportunities, and quality improvement support.
