Obstetric hemorrhage is a leading cause of severe maternal morbidity in Montana. To strengthen capacity of birthing facility teams to respond to obstetric hemorrhages using evidence-informed practices, the Montana Perinatal Quality Collaborative (MPQC) began implementation of the AIM Obstetric Hemorrhage Patient Safety Bundle in October 2021 with 17 of the state’s 26 birthing facilities. Between July 2021 and September 2022, the percentage of birthing facilities conducting hemorrhage risk assessments increased from 59.0% to 87.2%. During the same period, the percentage of participating birthing facilities who had policies and procedures in place to measure blood loss during the birth admission using quantitative and cumulative techniques increased from 23.5% to 68.9%. The MPQC continues to support hospitals in their quality improvement work and will assess and monitor rates of severe maternal morbidity as data are available.
