I looked at my own data from the past 12 months (N=30) for first-time mothers at term who experienced labour (so gone are the multip births, the scheduled cesareans for placenta previa, the premature births, etc.) Of the 87% of clients who did not have an induction, there were NO cesareans. Of the 13% of clients who had inductions, 100% of them had epidurals and 50% of those women had cesareans. Overall, of the 30 clients who fit the criteria (two were at home), the epidural rate was 40% and the overall cesarean rate was 13%. The numbers are small, but they still closely mirror the large study. Interesting stuff.
I will publish my complete stats for the past few years soon, and will tease out some more of the interesting results, including VBACs (I believe the past year's VBAC success rate was 100%), home birth stats, and more.
