try anything by susan foote, deborah stone, or dahl. right now i am reading a book on health care reform. it should be exactly what you are looking for. unfortunately it's at home so i'll post the title and author later this evening.
I read a great one a while ago by the former editor of JAMA on what is wrong with the healthcare system, and he makes some interesting suggestions about what to do about it. I believe the title was Severed Trust. I have the book at home, so I'll post all the info later tonight.
here's that book title i promised...
it's called "Governing Health: The Politics of Health Policy," the authors are Carol S. Weissert and William G. Weissert.
It's offers a good perspective. Hope this helps!!!
