I'm sorry if you're getting from what I'm writing that I'm judging you, I don't know you personally and I've never experienced your care, so I'm responding based on what you're writing. You asked why women would choose not to VBAC, so I responded with ways you might try to improve communication to get them to consider that. I've mentioned repeatedly that a supportive OB is hard to find and that the things you've said you do are exactly the reason I'd recommend a doctor like you to people I know. I've basically tried to explain, from a patients point of view, how some of your patients might feel based on your responses here which prompted you to respond that you can do "nothing right". I never said that you sited 50 % of patients leaving YOUR practice, I said that half of the reason women do leave ANY doctor is because of personality clashes and disdain with beside manner. I know I've done this myself. If that is not the case and you get along with your patients, wonderful, I hope you do because as I said I'd be happy to have an OB option that I could feel good about. I've used midwives with 2 of my 4 pregnancies because I have not had good experiences with OB's, but that doesn't make me feel that all of them are bad people and I have no reason to believe that you're the kind of doctor you say you are. My experiences have more to do with OB's who speak in terms of the only options being the options they see fit and the most natural birth I would be able to have would be tethered to a bed with constant fetal monitoring, no food or drink, etc so I have sought other options. That doesn't mean I believe all OB's are of the same mindset. I don't attempt to punish one person for what another has done. I'm simply responding to try to help, which was what I gathered from your original post that you wanted. Advice.
I think I'll stop trying to answer your question since it seems you don't feel there is an answer other than drug use and lack of concern from your patients. Maybe that is the case and it's nothing you're doing personally, so I suppose it's something you'll have to live with no matter how frustrating. And I'm sure it is very frustrating, it must feel a lot like when I read posts from women advising others to get epis immediately and schedule their C-sections in advance. Maddening.
I do know that if you contact the Bradley Method organization, they might be able to pass on your offer to instructors and students in your area, and you could potentially have classes right there in your office coordinated through that instructor. There are birth centers here who do the same thing, as well as offering infant massage, lactation consulting, doulas, etc and they are highly successful. Best of luck.
