The following is the link to Pennsylvania Hospitals statistics for 2008 on Cesareans and VBAC's. How does the hospital you are going to measure up to others in the state. I am sure glad I didn't have my children at Clarion Hospital I can tell you that much.
As expectant mom's you must also ask your care provider what their groups rates are too so that you have an accurate picture of your chances of vaginal birth are. Your hospital may have a 30% rate but your physician may have a 50% rate so you need to know that. If they can't tell you what their rates are shop around for a new provider.
