A recent article on November 3rd in the Chicago Tribune discussed cesarean section rates published for some Chicago hospitals. Swedish Covenant Hospital has one of the lower rates in Chicago at 25%. This rate represents all providers who deliver babies at Swedish Covenant including obstetricians, family practice physicians and nurse-midwives. Many individual providers track their individual practice’s cesarean rate, which might differ from the total hospital rate.
For the nurse-midwifery group at Swedish Covenant Hospital, our current cesarean section rate for 2009 is 15% and has been between 12-16% over the last decade. Our statistics for the last 3 years are posted @ www.swedishcovenant.org/midwives.
Healthy people 2010 from the U.S. Department of Health and Human Services suggest a target cesarean section rate of 15%. The American College of Obstetricians and Gynecologists suggest a benchmark for a first time cesarean section rate of 15.5% and repeat cesarean section rate of 37%. According to the CDC (Centers for Disease Control and Prevention) the U.S. total cesarean section rate is 31%. Many people are wondering, what does all this mean and what are the benefits to a lower cesarean section rate.
Women who have a cesarean birth have longer hospital stays and infant bonding interruption post partum which can lead to difficulties with breastfeeding. There are also increased rates of the following: hemorrhage, deep vein thrombosis, pulmonary embolism, increased infectious morbidity and placenta abnormalities in subsequent pregnancies. There are definitely instances when a cesarean section is necessary for the life of the mother or fetus, but current research does not support a 31% need.
There are consequences to multiple cesarean sections including placenta previa, placenta accreta, hysterectomy and bowel/bladder injury. Placenta previa and accreta can be life threatening for mom and baby and rates of occurrence go up with number of cesarean sections. A recent study in OB/GYN reviewed over 30,000 patients and found that women with a history of one prior cesarean section had a 3% chance of placenta previa. After 3 prior cesarean sections the rate reached 40%.
VBAC (vaginal birth after cesarean) rates in the U.S. have fallen since the 1990s, which contributes to the current rising cesarean section rate. VBAC is considered safe if performed in a hospital with continuous fetal monitoring, 24 hour obstetrician and anesthesiologist coverage available to perform a cesarean section urgently if needed. Two recent U.S. studies reviewing over 25,000 VBAC attempts reported a 75% success rate. If a woman has had a vaginal birth followed by a cesarean section, research shows that for subsequent pregnancies a VBAC attempt is safer than a repeat cesarean section. Currently many providers will not offer their patients a VBAC and will recommend a repeat cesarean section regardless of whether risks factors are present.
For women who are looking for a provider to partner with during their pregnancy considering the hospital’s cesarean rate is important, but also ask your individual provider what their rate of cesarean section is. Also discuss childbirth options and philosophy on childbirth with your provider. Educating yourself about pregnancy, labor and childbirth will empower you and your family to participate in decision-making which will leave you feeling more satisfied with your birth experience.
