Uterine Rupture Trends in Patients Pursuing Trial of Labor After Cesarean in the United States from 2010 to 2022.

National rates of trial of labor after cesarean (TOLAC) have increased, but the risk of uterine rupture remains. Clinical practice- and patient-level changes also have occurred in the past decade, and an evaluation of contemporary uterine rupture rates is needed. Using natality files available in the National Vital Statistics System from 2010 to 2022, we conducted a repeated cross-sectional analysis to evaluate U.

Validation of a Vaginal Birth After Cesarean Delivery Prediction Model Without Race and Ethnicity in Individuals With Two Prior Cesarean Deliveries.

Previous models for prediction of vaginal birth after cesarean (VBAC) relied on race and ethnicity, raising concern for bias. In response, the Maternal-Fetal Medicine Units Network (MFMU) created a new prediction model without race and ethnicity for individuals with one prior cesarean delivery. We performed a secondary analysis of the MFMU Cesarean Registry database to evaluate whether the MFMU VBAC prediction model without race and ethnicity could accurately predict VBAC for individuals with two prior cesarean deliveries.
