Black pregnant people are 20% more likely to get an unscheduled C-section than white pregnant people, even when controlling for factors like health status, hospital quality, and socioeconomic characteristics. The remaining 20% gap is driven by physician discretion.
C-sections, especially among low-risk mothers, carry higher risks of complications and can affect future pregnancies, often necessitating additional C-sections.
The study controlled for observable medical risk factors, hospital quality, and socioeconomic characteristics, using data from around 900,000 births in New Jersey from 2008 to 2017.
The gap suggests that physician decisions may be influenced by factors other than medical necessity, such as implicit bias or differences in communication styles.
Promoting diversity in the medical profession, ensuring mothers have advocates like doulas, and implementing value-based payments to reduce financial incentives for unnecessary surgeries are key systemic changes.
The team is considering studying other decisions around childbirth, such as inductions, to see if there are similar racial disparities and their health consequences.
Disparities in health are not indicated by adverse outcomes alone. Adriana Corredor-Waldron, an assistant professor of economics at NC State University, sought to understand why Black infants are more likely to be delivered by C-section than white infants. A working paper she co-authored found that the elevated number of low-risk Black pregnant people who were given C-section surgeries in New Jersey from 2008 to 2017 was likely caused by physician discretion. Corredor-Waldron explains why unnecessary C-sections can be risky and what medical education and financial incentives could do to close the gap.
