News — BALTIMORE (May 4, 2022) – University of Maryland Medicine, comprised of the University of Maryland Medical System (UMMS) and the University of Maryland School of Medicine (UMSOM), announced it has officially eliminated race as a factor in birthing decisions, which had become a national standard. The tool, called the Vaginal Birth After Cesarean (VBAC) calculator, included a modifier that assigned a higher risk of a complicated vaginal delivery to African American or Hispanic American women with previous surgical Cesarean section (C-section) compared to other women. This has led doctors, particularly at many community hospitals across the country, to be more likely to recommend a C-section to African American or Hispanic American women who had a previous one compared to women of other races or ethnicities.
The VBAC calculator was not frequently used at the University of Maryland Medical Center (UMMC), the System’s flagship academic medical center, or at the System’s hospitals in communities throughout the state. However, UM Medicine wanted to eliminate its use completely to ensure a race-free standard among physicians practicing in all UMMS hospitals.
As of May 1, UM Medicine has replaced the VBAC calculator with an updated assessment tool that excludes race or ethnicity as a risk factor. This revised calculator, VBAC 2.0, is endorsed by the , and adds consideration for a history of hypertension. UMSOM and UMMS leaders say the shift, which has been implemented across its statewide health system, could influence decision-making for thousands of births each year and have significant, sustainable impact toward establishing equity in maternal health.
“Racial disparities persist in nearly every field of medicine including obstetrics,” said , Executive Vice President for Medical Affairs, University of Maryland, Baltimore, and the John Z. and Akiko K. Bowers Distinguished Professor, and Dean, UMSOM. “As an obstetrician/gynecologist and a maternal-fetal medicine physician-scientist, I am in full support of the commitment of UMSOM and UMMS to mitigate inequities, including greater scrutiny of protocols in clinical practice and medical training. I am encouraged, not only by the immediate impact, but by the influence on the next generation of physicians.”
This latest change continues UM Medicine’s efforts to eliminate race-based clinical norms across its more than 150 UMMS locations as part of a broader commitment to reduce health disparities in the communities it serves. In January, UM Medicine transitioned to a race-free algorithm used to , increasing access to specialty care or transplantation for thousands of African American people living with advanced kidney disease.
“Reducing health disparity outcomes, especially those rooted in the inappropriate use of race or ethnicity as proxies for perceived biologic differences, is a principal priority for UMMS,” said the System’s Chief Diversity, Equity and Inclusion Officer, . “It starts with building stronger consciousness and working collectively to reinforce the vital importance of science and integrity in unraveling the structural and systemic inequities that have contributed to pervasive disparities in care and outcomes.”
Originally published in 2007, the VBAC calculator identified age, body mass index, history of vaginal delivery, or prior cesarean, along with race and ethnicity as key predictors. Rates of VBAC for African American and Hispanic American women have historically lagged somewhat behind those of white women or any other ethnic group according to the This matters, because while an elective C-section may be the safer option for many mothers, experts agree that the risk of complications is higher with repeat cesarean births as compared to a successful VBAC. These include excessive bleeding, infection or blood clotting issues. Such complications often come with longer, costlier recovery times or even potential complications in future pregnancies, including a need for repeat cesarean section for subsequent deliveries.
“It should never be a given that a woman of any race should undergo a repeat C-section after a prior uncomplicated cesarean delivery,” said , Associate Professor of Obstetrics, Gynecology and Reproductive Sciences at UMSOM, Chief of General Obstetrics and Gynecology at the University of Maryland Medical Center, and Chair of the UM Medicine Obstetric Patient Safety Committee. “Consideration of a trial of labor toward vaginal birth can and should be a part of an informed, patient-centered discussion and shared decision-making process. Taking race and ethnicity out of the decision-making equation is an important step toward eliminating racial and ethnic disparities in maternal health and I’m proud that UMMS and UMSOM are among the leading institutions to decisively take this action.”
Assessment algorithms are just one tool physicians draw from for clinical decisions, but leaders in obstetrics and gynecology welcome the move to a more equitable standard for every practice across the system. They also note that comprehensive sustainability of the practice change requires ongoing education and advocacy – elements UMMS leaders say make the close partnership with UMSOM critical.
In recent years, progress has been made through widespread acceptance that the concept of race is a social construct, not based in biology. Leaders in the medical field, however, concede that well-established standards that are deeply ingrained in medical practice take time to unravel. UM Medicine is currently undergoing a systematic review of each of the race-corrected clinical algorithms cited in a highly referenced article. The process could lead to more changes down the road to reverse racial bias in medicine.
In addition to taking coordinated, evidence-based actions with real and immediate impact, UMMS continues to take a leadership position in this movement with an important viewpoint of its own. In a , Joseph L. Wright, MD, MPH, Vice President and Chief Health Equity Officer for the system, notes it is critically important to understand the genesis of race-based medicine in order to unwind its roots.
“Acknowledgement of the ill-advised actions that have characterized these race-based clinical algorithms requires purposeful analysis and dismantling of those that are not embedded in science,” Dr. Wright said.
