The hospital where my old OB practiced has a rate even higher than that. It is one of the reasons I dumped the practice. Often when a hospital has a high rate, it's because they have bad policies in place about requiring certain interventions if you don't reach specific progress milestones within a given timeframe. For example, another friend delivered at a Santa Monica hospital, and the doctor told her, "We really don't like to see moms go past 40 weeks, so we will schedule an induction at that point if you haven't gone into labor."
Are you confident that your OB will respect your labor and birth plan? If you are, and if you are fairly certain that it will be your OB attending your birth (beware: no guarantees of that when they are part of a large practice or affiliated with a large hospital with a dedicated L&D department), then it might not be worth jumping out of the frying pan and into the fire. If you have good alternatives, like a respectable nurse-midwife practice near you, it might be worth researching those. Good luck.
