In 1952, when Dr. Virginia Apgar developed her 10-point scale for assessing neonates’ health, the U.S. obstetrical anesthesiologst may not have foreseen it would one day become one of the commonest medical tests in the world.
Assigned even before the mother first holds her newborn, the score rapidly evaluates neonates with a score of 0-10, which leads to an algorithm of potential medical interventions. The scale evaluates heart rate, respiratory effort, muscle tone, reflex response, and skin coloring (typically described as blue body, pink body/blue limbs, or pink body).
“The Apgar is a very important tool used in millions of babies around the world in the very first minute after birth,” said Amos Grunebaum, MD, a professor of obstetrics and gynecology at Hofstra University, Hempstead, N.Y., and director of perinatal research at Northwell Lenox Hill Hospital in Manhattan.
But recently the venerable system has increasingly come under fire for colorism and racial bias, with some calling for an overhaul. That pressure is due to the 2 out of 10 points allotted to an overall “pink” skin tone, a measure that lowers the scores of non-White newborns and may expose them to unnecessary measures such as resuscitation, neonatal intensive care, and intubation.
“This is their first encounter with systemic racism,” said Dr. Grunebaum in an interview. “The score is prejudiced against Black babies because they can’t get perfect scores.”
Propagating ‘race-based medicine’
Concern about racial bias embedded in the Apgar score is not new, Dr. Grunebaum noted.
“Decades ago, when I was doing my training in Brooklyn, the nurses said that using skin color was ridiculous since Black and brown babies couldn’t be pink. And skin color looks different in different lighting. Dr. Apgar herself recognized the problem.”
Furthermore, men see color differently than women do, and some people are actually color-blind.“But nobody wanted to speak out,” Dr. Grunebaum said. “It was like the emperor’s new clothes scenario.”
In his view, embedding skin color scoring into basic data and health care decisions propagates race-based medicine. “It should not be used for White, Black, or brown babies,” he said.
Removing the skin color portion of the Apgar score – and its racial, colorist, and ethnic bias – will provide more accurate and equitable evaluation of newborn babies worldwide, Dr. Grunebaum said.
“I think there’s a pretty good argument to be made that the skin color measure should be eliminated,” agreed Sara E. Edwards, MD, an obstetrician-gynecologist at the University of Illinois Hospital in Chicago, who has also studied Apgar and racial bias in the clinical care of Black babies.
And such clinical bias may soon be illegal in the United States thanks to a proposed new antidiscrimination provision to the Affordable Care Act regarding the use of clinical algorithms in decision-making. The proposed section, § 92.210, states that a covered entity must not discriminate against any individual on the basis of race, color, national origin, sex, age, or disability through clinical algorithms used in decision-making. Hospitals may soon have to alter clinical algorithms in response.
Dr. Grunebaum’s research in the area of clinical racism includes a large 2022 cohort study of almost 10 million mothers and more than 8 million fathers using 2016-2019 natality data from the National Center for Health Statistics, and Division of Vital Statistics. This study found that Black newborns had a less than 50% chance of having a 5-minute Apgar score of 10, compared with White newborns. White babies, both non-Hispanic and Hispanic, had the highest proportion of perfect 10s.
But can the 2-point skin tone indicator be easily replaced? According to Dr. Grunebaum, substituting indicators such as oral mucosa color or oximetry readings are not satisfactory either. “For one thing, oximetry gives different readings in Black [people],” he said.
In her group’s Apgar research, Dr. Edwards found that care providers applied variable and inaccurate scores based on neonatal race – independently of clinical factors and umbilical-cord gas values.
“In Black neonates umbilical cord gases were not in agreement with lower Apgar scores,” she said. In her view, these inaccuracies point to the existence of colorism and racial bias among health care providers.
