if the only research that will satisfy those with authority and power is research that is unfeasible, the controversy will never be resolved. There could be 20 more large, observational studies that come to the same conclusion as those that already exist, but they still wouldn't be randomized controlled trials. The home birth advocates would continue to say "The research proves it's safe!" and the American medical establishment would continue to say "The research isn't good enough!"
And, as she points out, evidence of homebirth dangers will continue to be produced via anecdote and rounds of "birth telephone".
If anything, I could have done with this article being a lot longer. I liked that she acknowledged the presence of the (in)famous Dr. Amy and Dr. Amy's "debate" site, and I'd like to see her really dig into the statistical discussion, the evidence base, and the depth and breadth of the barriers to translating evidence into practice. Perhaps you'd like to write another book, Jennifer Block?
In the meantime, props to Babble. At a wedding a few weeks ago, I ran into someone I know who works there and I told her I really liked Jennifer Block's response to Hanna Rosin, which they ran. Next time I see her I'll have to add my thanks for this. I hope they keep up the Jennifer Block connection, or at least keep running articles in this vein.
