Did you know that up to 80% of women attempting a VBAC successfully deliver without surgical intervention, making it a safe and cost-effective alternative to repeat cesareans for many?
Demographic and Societal Influences
- Approximately 75% of women who attempt VBAC do so because they prefer a vaginal birth experience
- The maternal request for VBAC has increased by approximately 15% over the past decade, reflecting patient preference trends
- The average age of women attempting VBAC is approximately 31 years old, reflecting broader demographic trends

Health Outcomes and Safety
- Women who attempt VBAC have about a 7% risk of uterine rupture
- VBAC is associated with decreased maternal morbidity compared to elective repeat cesarean
- The risk of receiving a blood transfusion after VBAC is lower than after repeat cesarean
- The American College of Obstetricians and Gynecologists recommends offering VBAC as a safe option for appropriately selected women
- Hospitals with higher VBAC rates tend to have better maternal satisfaction scores
- Use of continuous fetal monitoring during VBAC can reduce the risk of adverse outcomes
- Women with a history of emergency cesarean are less likely to attempt VBAC than those with scheduled cesareans
- The maternal mortality rate for planned VBAC is comparable to that for spontaneous vaginal delivery, approximately 0.02%
- Repeat cesarean deliveries are associated with increased risks of placental abruption, placenta previa, and hysterectomy, compared to VBAC
- The average hospital stay for VBAC is shorter by about 1.5 days compared to repeat cesarean
- Postpartum recovery time is generally faster in women who have a successful VBAC compared to those with cesarean, with an average of 2-3 days shorter hospitalization
- Overall, VBAC is associated with a lower risk of postpartum hemorrhage compared to elective repeat cesarean
- Women who attempt VBAC are more likely to experience fewer surgical adhesions compared to those undergoing repeat cesareans, facilitating future pregnancies
- The primary reason for women choosing VBAC is to avoid major abdominal surgery, which accounts for over 70% of all VBAC cases
- VBAC is associated with a lower incidence of respiratory complications in the newborn compared to scheduled cesareans
- Fewer than 1 in 400 women attempting VBAC will experience a uterine rupture with appropriate monitoring
- The risk of infection post-cesarean is about 3-5%, whereas in VBAC, it is significantly lower, approximately 1%
- Advances in hospital policies and improved training have helped increase VBAC success rates nationally, with some hospitals reaching over 75%
- The incidence of stillbirth is not increased in women attempting VBAC compared to women having a repeat cesarean
- The perception of safety among healthcare providers influences VBAC rates significantly, with some regions reporting rates as low as 5% due to provider reluctance
- The overall maternal morbidity rate in VBAC is about 4%, lower than in repeat cesarean, which can be over 6%
Health Outcomes and Safety Interpretation
Healthcare System and Hospital Policies
- VBAC reduces the overall healthcare costs associated with delivery, estimated savings of approximately $1,000 per birth
- Women in rural areas are less likely to attempt VBAC due to limited hospital facilities and availability of skilled personnel
- About 87% of women who have a prior cesarean and no contraindications are offered the option of VBAC
- The majority of women attempting VBAC do so in hospitals with designated protocols for TOLAC (trial of labor after cesarean), contributing to safety
- The use of hospital VBAC registries has been instrumental in improving success rates and safety monitoring, with some registries covering over 50% of deliverers
Healthcare System and Hospital Policies Interpretation
Maternal and Neonatal Risks
- The risk of neonatal death in VBAC is approximately 0.04%
- The risk of placenta accreta in women with prior cesarean sections increases significantly, impacting decisions around VBAC
- The overall rate of uterine rupture during VBAC is approximately 0.5%, but with variations based on clinical factors
- The risk of surgical complications in repeat cesarean delivery increases with each subsequent surgery, making VBAC a potentially safer alternative
- The rate of shoulder dystocia during VBAC is similar to that in women without prior cesareans, around 1.4%
- Only about 5-10% of women attempting VBAC will require an emergency cesarean, typically due to failed labor progression or fetal distress
- The maternal satisfaction rate with VBAC is over 90%, citing personal preference and recovery experience
- The recurrence rate of cesarean in women who attempt VBAC is approximately 20-25%, depending on various clinical factors
