Maternal mortality in the United States

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Maternal Health

Background:

• US maternal mortality ratio has seen little progress since 1982, despite earlier improvements.
• Most maternal deaths are preventable, according to the US Centers for Disease Control and Prevention.
• Significant underestimation of maternal mortality and persistent racial disparities are key issues.

Purpose of the Study:

• To analyze the trends and contributing factors of maternal mortality in the US.
• To highlight the challenges and opportunities in reducing preventable maternal deaths.
• To emphasize the importance of addressing racial disparities and near-miss cases.

Main Methods:

• Review of historical and current maternal mortality data.
• Analysis of factors contributing to the plateau in maternal mortality, including delayed childbearing and multifetal pregnancies.
• Examination of causes of pregnancy-related mortality, including thromboembolic disease, hemorrhage, hypertension, infection, and trauma.

Main Results:

• Maternal mortality has stagnated since 1982, with significant racial disparities.
• Delayed childbearing, older reproductive age, multiparity, and multifetal pregnancies contribute to increased risk.
• Peripartum cardiomyopathy, thromboembolic disease, hemorrhage, hypertension, infection, and traumatic injuries are major causes of maternal death.

Conclusions:

• Reducing maternal mortality requires addressing preventable factors and persistent racial disparities.
• Understanding the impact of delayed childbearing and new trends like cesarean delivery on maternal request is essential.
• Learning from "near-miss" cases offers a promising avenue for improving maternal safety and outcomes.
