From the N.Y. Times:
The national Caesarean rate, 31.8 percent, has been rising steadily for the last 11 years and is fed by repeat patients. Critics say that doctors are performing too many Caesareans, needlessly exposing women and infants to surgical risks and running up several billion dollars a year in excess bills, precisely the kind of overuse that a health care overhaul is supposed to address.
In fact, the rate of vaginal birth after Caesarean (VBAC) is now below 10%. Some doctors claim that VBACs risk tearing the mother’s scar tissue on her uterus, but others–including the profiled women on a Navajo reservation–successfully undergo multiple VBACs. Why are the rates VBAC rates so low?
- Fears of malpractice
- Physicians make more money Caesarean rather than a vaginal birth
- Caesarean’s use fewer physician hours than vaginal births
- Fewer expected number of pregnancies
- Patient demand
Why are Caesarean rates so much lower on the Navajo reservation? On the reservation, physicians are federally insured against malpractice, are paid a salary, and the use of midwives is much more common. Additionally, Navajo “couples often want more than two children, but repeated Caesareans increase the risk of each pregnancy, so doctors and patients are motivated to avoid the surgery.”
