Molly Schnell, an assistant professor of economics at Northwestern University, dives into the alarming racial disparities in C-section rates, revealing that Black mothers are 25% more likely to undergo unscheduled C-sections than their white counterparts. She discusses the implications of implicit bias in healthcare and the potential financial incentives affecting medical decisions. Exploring big data, Molly emphasizes the need for policy changes, such as promoting doulas and increasing workforce diversity, to improve maternal outcomes and combat these disparities.
A significant racial disparity exists in C-section rates, with Black mothers 25% more likely to have uncontrolled deliveries by C-section than white mothers.
Understanding the interplay of implicit biases and financial incentives in healthcare is crucial for addressing the racial gap in C-section rates.
Deep dives
Overview of C-Section Rates in the U.S.
Around one-third of all deliveries in the U.S. are cesarean sections, with only about 16% being planned. High rates of C-sections are concerning, as they are major abdominal surgeries that carry risks for both mothers and babies. The World Health Organization suggests that only 10 to 15% of births should be C-sections, indicating a possible overuse in the U.S. Notably, a significant racial disparity exists, with Black women disproportionately affected by higher C-section rates compared to their white counterparts.
Factors Contributing to Racial Disparities in C-Sections
Black mothers are found to be 25% more likely to have an unscheduled C-section compared to white mothers, even after considering various factors like maternal health and hospital type. Possible explanations for this disparity include differences in health risk at the time of delivery, variations in hospital practices, the racial bias of providers, and patient requests. Despite various hypotheses, understanding the core reasons for these disparities is essential for creating effective solutions. Without addressing these underlying issues, it is challenging to formulate policies to lower C-section rates among Black mothers specifically.
Methodology of Addressing C-Section Disparities
The research employs detailed administrative data from New Jersey to analyze C-section rates, focusing particularly on unscheduled deliveries. This innovative approach helps to evaluate medical risk and compare the likelihood of C-sections among mothers of different racial backgrounds. By predicting each mother's appropriateness for a C-section based on a decade's worth of data, the study finds that racial disparities persist even amongst similar risk profiles. This indicates the need to assess factors beyond observable health conditions, such as potential biases in clinical judgment.
Implications of C-Section Rates on Health Outcomes
When analyzing the impact of C-sections on maternal and infant health, it becomes evident that unnecessary C-sections for low-risk mothers lead to additional complications. Low-risk mothers experiencing unnecessary C-sections have a higher risk of surgical complications, while their infants face increased chances of NICU admissions. Conversely, postponing necessary C-sections for high-risk mothers is linked to poorer health outcomes for their babies. The findings emphasize the need for targeted interventions that prioritize minimizing unnecessary C-sections among low-risk populations while ensuring timely procedures for those at higher risk.
When we talk about C-sections, it’s often prefaced with “unplanned” or “emergency.” About a third of all the deliveries in the U.S. are cesarean sections, and only about 16% of those are planned. And that leaves a lot of mothers in a position where they’re delivering differently than they planned or intended to. And in the U.S., a disproportionate number of those are being performed on black women. So how are we going to get to the root of what's going on?
Today on ParentData, we're joined by Molly Schnell, whose paper “Drivers of Racial Differences in C-Sections” explores this phenomenon. Molly is an assistant professor of economics at Northwestern University and her paper found that black mothers with unscheduled deliveries are 25% more likely to deliver by C-section than white mothers. And she argues that implicit racial bias among providers or possibly even a financial incentive in hospitals to fill their operating rooms may play a role in this racial gap.
