Maternal mortality in the United States has been climbing over the last few decades.2 The U.S. maternal mortality rate in 2023 was 18.7 deaths per 100,000 births,3 compared to 10 deaths per 100,000 births in 1990.4 This means that the rate is almost double what it was 25 years ago.5
Rates of maternal deaths surged during the COVID-19 pandemic, but have since declined.6 According to provisional CDC data, 673 maternal deaths occurred in 2023.7 This is a decrease from 817 deaths in 2022 and 1,205 in 2021.8 However, the United States continues to have the highest rate of maternal deaths of any high-income country,9 and data shows massive disparities for women of color.10
The leading causes of maternal morbidity and mortality are hemorrhage and hypertensive disorders of pregnancy.11,12 Hemorrhage itself is the leading cause of maternal mortality worldwide.13 While hemorrhage can occur at any time during labor and delivery, it most commonly occurs postpartum and is defined by the term postpartum hemorrhage (PPH).
PPH is both common and incredibly dangerous, given how quickly a mother can bleed out. This is important in the context of structuring simulation drills. Labor and delivery teams need to recognize what’s happening, determine the cause, give medications, transfuse, resuscitate, and, if needed, transfer the patient to the operating room. PPH represents a radical change in the patient’s condition—and this a prime opportunity for simulation-based training.
Hypertensive disorders can also turn a patient case into an emergency. Identification of severe hypertensive disorders followed by rapid control by the labor and delivery team are essential—another area where patient simulation can help.
