"How does one legitimately comparison shop for a baby delivery?" How did you and your spouse decide on an ob/gyn when you were expecting your kids? How did you decide on a pediatrician after they were born? Would you be able to rate your experience with both/either after the fact (ie, did the experience live up to the reasons you chose them?)? Would it be possible to use such ratings along with costs to at least create some measure of efficacy for the specific providers or their hospitals/clinics? The outcome may not be a perfect solution, but it at least gives people some data points if they are interested in comparing doctors/clinics/hospitals for whatever their needs are.
