- Approximately one-third of deaths (31%) happened during pregnancy;
- Approximately one-third (36%) happened at delivery or in the week after; and
- Approximately one-third (33%) happened 1 week to 1 year postpartum.
- Heart disease and stroke cause the most deaths overall.
- Obstetric emergencies, like severe bleeding and amniotic fluid embolism (when fluid enters a mother’s bloodstream), cause most deaths at delivery.
- In the week after delivery, severe bleeding, high blood pressure and infection are most common.
- Cardiomyopathy (weakened heart muscle) is the leading cause of death one-week to one-year after delivery.
- Pregnancy-related deaths in the United States steadily increased from 7.2 deaths per 100,000 live births in 1987 to 16.9 deaths per 100,000 live births in 2016.
- Postpartum hemorrhage (PPH) is the leading cause of maternal mortality. National statistics suggest that approximately 11.4% of maternal deaths are caused by PPH.
- A recent study from the CDC Foundation notes that hospitals may be able to prevent up to 70% of hemorrhage-related obstetric deaths. This means that, with the right strategies, one of the most common causes of maternal mortality can be drastically reduced. Since black women have greater risk of death from postpartum hemorrhage than white women, improving postpartum hemorrhage care has significant implications for improving health equity.
