Race, Risk, and the VBAC Calculator: The Politics of Race Correction in Childbirth

"At first, I treated it as coincidence. Childbirth is unpredictable. Cesarean delivery can be lifesaving. Obstetric care is complex. No two births unfold the same way. But the pattern unsettled me, and I began to ask a different kind of question. Not just what was happening to these women, but what was shaping the information they were given when decisions were being made. What did these women actually know about how their risk was being calculated? And who, or what, had shaped that calculation before they ever walked into a consultation room?"

"VBAC refers to attempting a vaginal delivery in a pregnancy after a prior cesarean section. National clinical guidelines state that many patients who have had one prior cesarean are candidates for a trial of labor. The primary concern is uterine rupture at the previous scar site (uncommon, but serious). But repeat cesarean is not a neutral default. It is major abdominal surgery, with increased risks of infection, hemorrhage, and dangerous complications in future pregnancies. Each additional cesarean compounds that exposure. For many patients, the decision extends far beyond a single birth."

"But across the United States, VBAC became difficult to pursue even for patients who wanted it. Cesarean rates rose dramatically through the late 1990s and 2000s, reaching roughly one in three births today. During the same period, VBAC rates fell sharply, from around twenty-eight percent in 1996 to approximately eight percent by 2006. Liability pressures and institutional caution narrowed access to trial of labor."

Cesarean delivery became common, including scheduled procedures and emergency surgeries, yet outcomes often remained the same. A pattern prompted questions about what information shaped decision-making and how risk was calculated before consultations. VBAC refers to attempting vaginal delivery after a prior cesarean, and national guidelines indicate many patients can be candidates for a trial of labor, with uterine rupture as the main concern. Repeat cesarean is major surgery with higher risks such as infection and hemorrhage, and each additional cesarean increases future exposure. Across the United States, cesarean rates rose to about one in three births while VBAC rates fell from roughly 28% in 1996 to about 8% by 2006, influenced by liability pressures and institutional caution. A prediction tool emerged in 2007 to address these decisions.
