If you listen to the obstetricians, it's all about lawsuits -- they are at risk of being sued for "anything short of a perfect outcome," as two doctors wrote last week in a letter to the editor in the New York Times. But maybe the real issue is basic patient safety, and the failure of hospitals and doctors to have the right staffing necessary to make vaginal childbirth safe after a previous C-section.
