Code Crimson OB: A Lifeline for Maternal Health

Introduction: Postpartum hemorrhage (PH) accounts for 12% of maternal deaths in the U.S. and affects approximately 5% of obstetric individuals. Despite available treatments, delays in recognition and response can lead to severe complications or death. The purpose of this evidence-based practice project was to improve maternal outcomes by implementing Code Crimson OB, a specialized obstetric rapid response team (RRT) for managing maternal hemorrhage. Methods: An unannounced maternal hemorrhage drill revealed critical delays in mobilizing appropriate personnel. In response, the RRT protocol was revised to include Code Crimson OB, ensuring rapid, coordinated intervention. Hospital-wide education was conducted, and the protocol officially launched in May 2022, with the first activation in July 2022. Results: Following implementation, Code Crimson OB significantly improved response times and outcomes. There was a 90.9% reduction in transfers to higher levels of care, an 88.2% decrease in blood transfusions, and an 85.7% decline in emergency hysterectomies. Discussion: The success of Code Crimson OB supports its expansion to other maternal care sites within the health system. Plans are also underway to develop a similar rapid response protocol for non-obstetric hemorrhage cases hospital wide.
