The U.S. maternal mortality crisis
Dr. Shah, an ob.gyn. at Beth Israel Deaconess Medical Center and director of the Delivery Decisions Initiative at Harvard Medical School’s Ariadne Labs, both in Boston, where he has “been on this mission to improve safety in childbirth for years now,” echoed Ms. Saba’s dismay regarding the pace of progress.
“It’s not just about the present, it’s about the future, it’s about the pact that every generation ought to have with the next one to leave things at least as well as they found them. And when it comes to the health of our moms in this country, we are not doing that,” he said. “An American mom today is 50% more likely to die in childbirth than her own mother was, and 3-4 times more likely to die if she’s black than if she’s white.”
Indeed, the data released Jan. 30 by the CDC’s National Center for Health Statistics (NCHS) – the first on maternal mortality released by the agency since 2007 – show a U.S. maternal mortality rate of 17.4 maternal deaths per 100,000 live births in 2018.
The rate is higher than the 12.7 per 100,000 live births reported in 2007, but the increase is attributable mostly to changes in data collection and reporting methods. In 2003, “a consensus process recommended that all states add a standardized ‘checkbox’ to improve the identification of maternal deaths,” and implementation wasn’t complete until 2017 as “funding, technology, and state laws allowed,” meaning 2018 was the first year that data were reported in a standardized fashion across states, the CDC explained in a press release.
The data demonstrate ongoing wide racial/ethnic disparities: the maternal mortality rates for non-Hispanic black women, non-Hispanic white women, and Hispanic women were 37.1, 14.7, and 11.8 per 100,000 live births, consistent with earlier data.
Further, the rates for women aged 40 years and over were nearly eightfold higher than for those under age 25 years (81.9 vs. 10.6 per 100,000 live births).
CDC officials noted, however, that inconsistencies in reporting still leave some question about the accuracy of the data, stating in the release that “NCHS has identified instances where application of the checkbox information according to coding rules led to misclassification of maternal deaths.”
The agency is making changes in rules and reporting to ensure greater accuracy, but the numbers nevertheless reveal a startling truth: “The United States is the most dangerous place to deliver a baby in the industrialized world.”
Progress and challenges
Rebekah Gee, MD, an ob.gyn. who served for 4 years as Secretary of the Louisiana Department of Health before leaving the position in January, made that statement during another panel discussion at ACOG 2019 – The President’s Panel: Maternal Mortality: Progress Toward Prevention – which was moderated by Lisa M. Hollier, MD, now the immediate past president of ACOG.

That’s not to say progress hasn’t been or can’t be made, Dr. Gee said.
In fact, quality improvement measures she facilitated in Louisiana led to a 25% reduction in infant mortality and a 10% reduction in neonatal intensive care unit admissions, demonstrating the potential for improvement with such initiatives, but addressing maternal issues is a greater challenge, she said.
“I think part of the sad truth is that we really focus on babies first, not moms ... and that needs to change,” Dr. Gee said.
Dr. Hollier focused much of her attention during her tenure as ACOG president on doing just that, particularly through an emphasis on heart disease, which is the leading cause of U.S. maternal deaths in pregnancy and the postpartum period.
In an interview, she shared her thoughts on the progress achieved and the work that remains.
ACOG was instrumental in the enactment of the Preventing Maternal Deaths Act of 2018, which appropriated funding for Enhancing Reviews and Surveillance to Eliminate Maternal Mortality (ERASE MM), a CDC initiative to support state-based maternal mortality review committees, said Dr. Hollier, professor of obstetrics and gynecology at Baylor College of Medicine, Houston.
“The really great news is that almost immediately after passage of the legislation, the CDC put out the notice of the funding opportunity, and they were able to provide 24 awards supporting 25 states,” she said.
ERASE MM will enhance state data collection and availability and enable a level of data sharing that “will really add strength and depth to reporting from the maternal mortality review committees, which really provides us with the best information we have to truly understand the causes, the contributing factors, and the strategies that can be put in place to prevent future maternal deaths.”
Further, the Alliance for Innovation on Maternal Health (AIM) program, a cooperative agreement with the Health Resources and Services Administration (HRSA) Maternal and Child Health Bureau to improve safety and outcomes through evidence-based patient safety bundles, was extended, and in May 2019, ACOG updated its guidance on managing cardiac contributors to maternal mortality, releasing its “Pregnancy and Heart Disease” Practice Bulletin, she said.
Dr. Hollier continues in her quest for improved maternal outcomes. She is slated to deliver a keynote address at the American College of Cardiology/World Congress of Cardiology conference March 28 in Chicago.
“I’m so excited ... to talk about the new guidelines that we’ve put out and to really talk about how cardiologists and ob.gyns. can work together to improve women’s health outcomes,” she said, adding that she already is seeing a strengthening of such partnerships.
A number of academic institutions are developing “pregnancy heart teams” to identify and care for women who have or develop heart disease during pregnancy.
“This type of collaboration ... is going to be essential to address mortality from cardiovascular causes and from cardiomyopathy, which accounts for about 25% of all maternal mortality,” she said. “The next area where we really need some buy-in is from our emergency physicians.”
Enhanced collaboration with emergency physicians and other specialties present opportunities to better identify and address pregnancy-related complications and sequelae, she said.
“Women are dying because they’re not being diagnosed,” she added. “We have to raise that level of awareness – it’s just absolutely critical.”
