A patient safety bundle is a set of evidence-based interventions that has been shown to improve outcomes and safety in health care when performed consistently and reliably. This article describes a quality improvement project to implement the Alliance for Innovation on Maternal Health's Severe Hypertension in Pregnancy patient safety bundle to increase the percentage of patients who receive evidence-based treatment during hypertensive emergencies. After several cycles of plan-do-study-act, the percentage of patients receiving appropriate treatment increased from 64% to more than 80% and was sustained for 6 months.
