In Ohio, preeclampsia and eclampsia were found to be the leading causes of pregnancy-related death between 2008 and 2016, with 85% of those deaths determined by review to have been preventable. In 2020, Ohio began implementation of the AIM Severe Hypertension in Pregnancy Patient Safety Bundle in 30 of the state’s 91 birthing facilities. Between October 2020 and September 2021, the percentage of pregnant and postpartum people with persistent severe hypertension who were treated within one hour increased from 56.8% to 71.4%, an increase of 25.7%, with no statistically significant differences observed across racial and ethnic groups. As of April 2024, Ohio has reached 81 of its 91 birthing facilities through the AIM Severe Hypertension in Pregnancy bundle. The Ohio Hospital Association and Ohio Department of Health continue to work with birthing facilities to expand the bundle to all hospitals in the state and sustain improvements among those already participating in patient safety bundle implementation.
