In the United States, the rate of mortality caused by severe maternal morbidity has improved over time, but failure to rescue is significantly more common among racial and ethnic minorities.
These failures are a “major contributing factor” to the disproportionately higher rate of maternal mortality among women of color, reported lead author Jean Guglielminotti, MD, PhD, of Columbia University, New York, and colleagues.
“Racial and ethnic disparities in severe maternal morbidity are a growing public health concern in the United States,” the investigators wrote in Obstetrics & Gynecology.
“The reported incidence of severe maternal morbidity is twofold to threefold higher among Black American women, compared with non-Hispanic White women; and although the difference is less pronounced, the incidence of severe maternal morbidity also is higher among Hispanic, Asian and Pacific Islander, and Native American women.”
The ensuant, disproportionate risk of maternal mortality may be further exacerbated by disparities in hospitals, according to the investigators. They noted that non-Hispanic White women tend to give birth in different hospitals than racial and ethnic minorities, and the hospitals serving people of color “are characterized by lower performance on maternal safety indicators.”
Even within hospitals that most often serve minorities, severe maternal morbidity is more common among women of color than women who are White, they added.
“However, the simple severe maternal morbidity rate is insufficient to assess hospital performance and should be complemented with the rate of failure to rescue,” wrote Dr. Guglielminotti and colleagues.
Measuring failure to rescue across racial and ethnic groups
According to the investigators, failure-to-rescue rate advances focus from complications themselves – which can occur when care is appropriate and may stem from patient characteristics – to a hospital’s response to such complications.
Using this metric, a 2016 study by Friedman and colleagues, which included data from 1998 to 2010, showed failure to rescue was more common among Hispanic and non-Hispanic Black women than white women.
The present study built upon these findings with data from almost 74 million delivery hospitalizations in the National Inpatient Sample (1999-2017). The population included 993,864 women with severe maternal morbidity, among whom 4,328 died.
Overall, the failure-to-rescue rate decreased over the course of the study from 13.2% in 1999-2000 to 4.5% in 2017 (P < .001).
Yet racial and ethnic inequities were apparent.
Compared with White women, non-Hispanic Black women had a significantly higher failure-to-rescue rate ratio (1.79; 95% CI, 1.77-1.81), as did Hispanic women (RR, 1.08; 95% CI, 1.06-1.09), women of other non-White racial/ethnic backgrounds (RR, 1.39; 95% CI, 1.37-1.41), and women documented without racial/ethnic designations (RR, 1.43; 95% CI, 1.42-1.45).
“Failure to rescue from severe maternal morbidity remains a major contributing factor to the excess maternal mortality in racial and ethnic minority women in the United States,” the investigators concluded. “This finding underscores the need to identify factors accounting for these disparities and develop hospital-based interventions to reduce excess maternal mortality in racial and ethnic minority women.”
Striving for progress through systemic change
According to Eve Espey, MD, MPH, of the University of New Mexico, Albuquerque, “this study adds to the literature demonstrating that structural racism and implicit bias have profound negative impacts,” which “has implications for action.”
“We must increase efforts to improve maternal safety, including the rollout of Alliance for Innovation on Maternal Health [AIM] bundles through statewide perinatal quality collaboratives,” Dr. Espey said. “AIM bundle implementation must focus on the context of health inequities related to racism and bias. Similarly, we must consider large scale public policy changes building on the Affordable Care Act, such as universal health coverage throughout the life span, [which] equitably increases access to quality health care for all.”
Constance Bohon, MD, of Sibley Memorial Hospital, Washington, offered a similar viewpoint, and suggested that further analyses could reveal the impacts of systemic changes, thereby guiding future interventions.
“It would be interesting to determine if declines in failure to rescue rates were greatest in states that implemented AIM safety bundles [in 2012] as compared with the states that did not,” Dr. Bohon said. “The same assessment could be made with a comparison between the states that did and those that did not approve the Medicaid expansion [in 2014]. Other beneficial data would be a comparison of the failure-to-rescue rates in hospitals that provide the same obstetrical level of care. Further studies need to be done in order to identify factors that have the greatest impact on the failure-to-rescue rate. Subsequently, proposals can be suggested for actions that can be taken to decrease the excess maternal mortality in racial and ethnic minorities.”
Comparing the U.S. with the rest of the world
In an accompanying editorial, Marian F. MacDorman, PhD, of the University of Maryland, College Park, and Eugene Declercq, PhD, of Boston University, put the findings in a global context.
They noted that, in the United States over the past 2 decades, the rate of maternal mortality has either remained flat or increased, depending on study methodology; however, the relative state of affairs between the United States and the rest of the world is more straightforward.
“What is clear is that U.S. maternal mortality did not decline from 2000 to 2018,” wrote Dr. MacDorman and Dr. Declercq. “This contrasts with World Health Organization data showing that maternal mortality declined by 38% worldwide and by 53% in Europe from 2000 to 2017. In fact, North America was the only world region to not show substantial declines in maternal mortality during the period, and U.S. maternal mortality rates are nearly twice those in Europe.”
Within the US, these shortcomings are felt most acutely among racial and ethnic minorities, they noted, as the present study suggests.
“The U.S. is still plagued by wide racial disparities, with similar or larger Black-White maternal mortality disparities in 2018 than existed in the 1940s,” they wrote. “Thus, any euphoria generated by the lack of increase in maternal mortality (if accurate) must be set in the context of worldwide improvements, in which the U.S. is an outlier with no improvement. The U.S. can and should do better!”
To this end, Dr. MacDorman and Dr. Declercq wrote, “additional training and vigilance among clinicians can help to avert these largely preventable deaths. In addition, applying this same rigor to preventing deaths that occur in the community before and after birth, combined with a focus on social determinants among women during the reproductive years, will be essential to lowering U.S. maternal mortality overall and eliminating longstanding racial inequities.”
The study received no external funding. The investigators reported no conflicts of interest.
