One would think that with all the technology we have available and modern science there is no question about the safety of having a baby in the United States of America. Upon a close examination, there are some alarming trends that say otherwise. In this article, I address some of the factors causing the rising maternal death rate, the disparities in outcomes between black and white women, and the differences between the medical and midwifery models of care for birth.
According to the CDC 2015 National Vital Statistics Reports, approximately 98 percent of women give birth in the hospital with the majority of the remaining 2 percent giving birth at home (Martin, Hamilton, Osterman, Driscoll, and Matthews, 2017). One in three women nationwide are giving birth by cesarean section, which has its own set of risks for the mother, including infection, injuries to the bowel or bladder, blood loss, blood clots, and reactions to anesthesia or medications used for the surgery (Gregory, Jackson, Korst and Fridman, 2011). As with any major surgery, there is always a risk of death from complications.
In the United States, 26.4 out of 100,000 women die in childbirth every year (Kassebaum et al, 2016, as cited in The Lancet 388(10053). As can be seen in the chart below, we are the only country out of 13 other industrialized nations with a rising maternal death rate (i.e. death from pregnancy-related complications) (Kassebaum, et al, 2016).

For every woman who dies in childbirth, there are 70 near deaths (Kilpatrick and Berg, 2016). That adds up to more than 50,000 women every year. Black women are 3-4 times more likely to die in childbirth than white women, and 12 times more likely to die in NYC (Creanga, Syverson, Seed, Callaghan and William, 2017). There has been much research indicating that the cause of this disparity between black and white deaths is systemic, societal racism (Prather, Fuller, Marshall and William, 2016). There is physiological stress that stems from simply being a black woman in a white dominant culture.
Amani Nuru-Jeter (http://sph.berkeley.edu/amani-nuru-jeter), a social epidemiologist at the University of California, Berkeley, has been doing research to find out how as she puts it, racism gets under the skin. Nuru-Jeter has authored many articles on how race, and socioeconomic status contribute to stress, which contributes to chronic inflammation. This inflammation is the cause of many conditions; including cardiovascular disease. We know that stress hormones interfere with all of our biological systems, and can lead to many health problems, including during pregnancy.
There is no one single cause to blame for the rising maternal death rate in the United States. One thing is certain; there are two very distinct models of care for birth: the midwifery model and the medical model. It matters greatly which model of care is primary. The World Health Organization (2011) states, “In countries all over the world, retrospective studies attest that quality midwifery services are a well-documented component of success in saving the lives of women and newborns as well as promoting their health” (p 1). A Cochrane Review that included 15 trials involving 17,674 women,” suggests that women who received midwife-led continuity models of care were less likely to experience intervention and more likely to be satisfied with their care with at least comparable adverse outcomes for women or their infants than women who received other models of care.” (Sandall, J et al, 2016, p 2)
The midwifery model takes into account the individual woman and her family, and treats birth as a normal physiological process, while the medical model views birth as a crisis waiting to happen, with management and intervention at its core. Buckley (2015) points out that the medical interventions so commonly used in labor and birth disrupt the biological process and the hormones that would normally be activated for childbirth. This interference has long-range negative implications far beyond the birth. The hormone disruption also impacts bonding and breastfeeding.
Evidenced-based care takes into consideration the individual who requires the care, and what their wishes are. It also accounts for the latest best available external evidence and the expertise of the clinical care provider. In this context, some birthing women will need access to the medical intervention due to a medical condition, disease, or circumstance that could cause their labor and birth to stray from the normal physiological process. However, most healthy pregnant women can give birth without any intervention, with a trained midwife in attendance. Yet, in the Listening to Mothers Survey (2013), over 40% of U.S. women reported that they were induced to bring on labor. This single intervention can lead to a whole host of interventions, often referred to as the cascade.
One intervention can lead to another. Often times with induction the contractions become irregular and unbearable, as the body’s own endogenous endorphins can be prohibited from activating as they would with a normal physiologic birth. Many women request epidural once artificial induction has begun. Epidural requires administration of lots of fluid and careful monitoring because mother and baby are both at risk for a suppressed respiratory rate. Epidural also limits a woman’s mobility during labor and birth. This can lead to a cesarean section, a long labor, or complications for the mother or baby. There is always a risk with any intervention; whether it be infection, lasting pain, increase the risk for future complications, or, even death.
Access to Care
The long-term investigation done by ProPublica found several additional factors driving the rising U.S. maternal death rate. First and foremost is the access to care problem. Ideally, there will be a choice of hospital, birth center, and home. Women who have access to choice have the opportunity to give birth freely, exactly how they want to. This is where the first problem lies. In the United States, we do not have equal access to care. The color of one’s skin, and whether or not one has insurance or money affect access to care. In addition, there have been maternity hospitals in rural areas closing down, leaving many women without this choice, or forcing these women to commute an average of 29 miles more to get to prenatal care (Hung et al, 2016). Most of these closings are in areas that are economically disadvantaged, and also have fewer practitioners to begin with. Labor and birth units are very expensive to operate, with equipment that one sees in an intensive care unit. At the same time, midwifery, especially for homebirth, is still illegal in some states.
Provider Training
Let’s say the first problem doesn’t exist. Access to care is equal for all. What else would be driving the rising maternal death rate? One interesting fact uncovered in the ProPublica and NPR research is that many doctors in the United States who enter the obstetric field never step foot on a labor and birth unit. Mary D’Alton, chair of OB-GYN at Columbia University Medical Center, and one of the country’s foremost experts on maternal-fetal medicine told the researcher that a doctor may be responsible for life and death situations which they have never encountered, witnessed or been prepared for. (Dalton, ME et al 2013)
Another alarming fact in the same article referenced above is that there are no standard protocols in place in many hospitals, to deal with a major emergency. The hospitals are well equipped to observe and handle newborn complications, but not the complications that could arise for the newborn mother. We are not doing a very good job at observing mothers after birth. For example, you could be a healthy pregnant woman who had an uncomplicated pregnancy and either die or nearly die from childbirth. Women go home after birth with infections undetected, retained placenta, and symptoms related to pre-eclampsia. Inducing women to solve the problem of pre-eclampsia is not necessarily the solution. Yet, this is the protocol administered fairly routinely. According to the Pre-Eclampsia Foundation (2018), “97% of maternal deaths related to preeclampsia happen in the postpartum period.” (Creanga, A. (2017)
Failure to Listen to Women
This is another problem uncovered by the ProPublica and NPR investigation. Women have reported that they knew something was wrong but were told it was a normal after-birth reaction. Some persist and get the care they need, while others aren’t listened to fast enough to save their life. Many of the deaths are completely preventable. In many hospitals it isn’t routine to share information about warning signs, and when to seek medical attention. Listening to women is one of the most important things we can do to change what is happening. And, of course, educating women and families about the warning signs.
Unfortunately, the United States government stopped collecting accurate and up to date records of maternal deaths over a decade ago, and isn’t doing a very good job at tracking the near deaths. The way records are kept and recorded varies from state to state, and hospital to hospital. Not everyone asks questions about pregnancy, which alters the statistics for the maternal mortality rate. “It is an international embarrassment that the United States, since 2007, has not been able to provide a national maternal mortality rate to international data repositories such as those run by the OECD. This inability reflects the chronic underfunding over the past two decades of state and national vital statistics systems” (MacDorman et al, 2016, p.454). Perhaps this is a reflection of a cultural view on mothers, mothering, and women’s work. It is viewed as less important, and not equal to “real work.”
Mother’s health and lives matter greatly. It is a great indicator of the health of our nation.
The United States can do better. We can learn from the California Maternal Quality Care Collaborative, where they have been gathering the data, developing toolkits, and improving outcomes. We can also learn from other countries where the midwifery model of care proves to produce better outcomes.
There are many solutions to the challenges we have with the United States maternity care system. Knowledge is power. Educating women early in pregnancy or before pregnancy, about the normal physiological process of birth, training providers, and using the midwifery model of care as the norm would improve outcomes significantly. Women and families deserve better.
