The difference in c-section rate in the Hannah study was only 3 percentage points between the two management groups, so I reason that if routine induction fails only 4% of the time ( a pretty reasonable assumption), and is always follwed by a section, you'll end up with a higher overall section rate.

It's not clear what happened in case of induction failure. Only 66% of those assigned to the induction group actually got induced. The answer might lie in the many pages of supplementary data which one can send for.

I don't know of such a study. But it stands to reason, just because you'll tend to get further cervical ripening after waiting a few days.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
