USMLE Guide: Maternal Mortality

An informative guide for the United States Medical Licensing Examination (USMLE)


Maternal mortality refers to the death of a woman during pregnancy or within 42 days of the termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management. It is an important topic in obstetrics and gynecology, and understanding the risk factors, causes, and prevention strategies related to maternal mortality is crucial for medical professionals. This USMLE guide aims to provide an overview of key points related to maternal mortality.


  • Maternal mortality is a global issue, but rates vary significantly between countries.
  • According to the World Health Organization (WHO), approximately 810 women die every day from preventable causes related to pregnancy and childbirth.
  • Sub-Saharan Africa has the highest maternal mortality rate, while high-income countries have the lowest rates.

Risk Factors

Several risk factors contribute to increased maternal mortality rates:

  1. Socioeconomic Factors: Poverty, limited access to healthcare, and lack of education are associated with higher maternal mortality rates.
  2. Geographic Factors: Rural and remote areas often lack adequate healthcare facilities and resources, leading to increased maternal mortality.
  3. Age: Pregnant teenagers and women over 35 years old have a higher risk of maternal mortality.
  4. Obstetric Factors: Pre-existing medical conditions (e.g., hypertension, diabetes), multiple pregnancies, and complications during pregnancy or childbirth increase the risk.
  5. Lack of Skilled Care: Insufficient access to skilled healthcare providers, including midwives and obstetricians, contributes to maternal mortality.

Causes of Maternal Mortality

Understanding the leading causes of maternal mortality is essential for effective prevention and management:

  1. Postpartum Hemorrhage (PPH): Excessive bleeding after childbirth, often due to uterine atony or trauma, is a leading cause of maternal mortality.
  2. Hypertensive Disorders: Pre-eclampsia, eclampsia, and gestational hypertension can lead to severe complications, including organ failure and death.
  3. Infections: Maternal infections, such as sepsis and postpartum infections, can rapidly progress and result in maternal mortality.
  4. Unsafe Abortion: In regions where safe abortion services are limited, unsafe abortion practices contribute significantly to maternal deaths.
  5. Obstructed Labor: Prolonged labor, often due to cephalopelvic disproportion or malpresentation, can lead to maternal mortality if not managed appropriately.

Prevention and Management

Efforts to reduce maternal mortality should focus on the following strategies:

  1. Improving Access to Healthcare: Expanding healthcare facilities, particularly in underserved areas, and providing transportation options can help ensure access to skilled care.
  2. Antenatal Care: Regular prenatal visits and screenings allow for early identification and management of potential complications.
  3. Emergency Obstetric Care: Availability of well-equipped obstetric facilities and trained healthcare providers is crucial for managing complications during pregnancy and childbirth.
  4. Family Planning: Access to contraception and family planning services helps prevent unintended pregnancies, reducing maternal mortality.
  5. Education and Empowerment: Educating women about their rights, health, and pregnancy-related complications empowers them to seek appropriate care and make informed decisions.


Maternal mortality remains a significant global health challenge. Understanding the risk factors, causes, and prevention strategies related to maternal mortality is essential for medical professionals. By employing effective prevention strategies and providing quality care, healthcare providers can contribute to reducing maternal mortality rates worldwide.
