My wife is a PA - here are a few things we've (anecdotally) noticed:
1. A few doctors left practices after they got taken over by a bigger entity and the hoops they had to jump trough weren't worth it, so they retired.
2. The insurance companies - they control EVERYTHING. One thing that happens a lot is that they don't allow her to order an MRI unless she orders an X-Ray first - even if what they're testing for wouldn't show up on an X-Ray. And this slows down the process of diagnosis by days. There are more examples of things like this - things that should be up to the provider, but end up being up to the insurance company (what drug to prescribe or what treatment to pursue first) - it makes no sense (at least from what I hear from her).
