Get over yourselves. What we do isn't rocket-science. Not all PA's are created equal. I have met some that are very good, and others who aren't.
My first PA was straight out of training. She spent 2 months shadowing me, and read the SIS guidelines cover to cover. We had a retired PM&R inpatient doc on staff at the time, and he taught her how to take a detailed H&P. Then she saw patients. Sure, she made mistakes, but she didn't make them twice.
She just left, and we hired the local spine surgeon's PA, who has been in practice for more than a decade. He spent a month with the prior PA. It's like having a surgeon in the practice. He brings a different perspective, and is a resource I can draw on.
PA's can be very useful. The devil is in the details. You have to put in the time to train them. And anytime they have a question, you have to take the time to explain your thought process. They have to be smart enough to understand, and retain the information. They also have to be willing to learn, and humble enough to ask when they don't know. Clearly, they can handle the straight forward cases. They have to recognize when to ask for help.
I don't know everything. Even about pain. I have a group I go to when I need insight. I find admitting I don't know the answer wasn't my strong suit, and has only come as I matured. (insert insult/joke/wise ass snarky comment here)
There are pain docs I wouldn't let touch my pets. There are others (albeit just a few) who I would ask to to a C/S TF-ESI if I needed one. Mid-level are exactly the same. Some are terrific. Others are terrible. Anyone who makes an overarching statement about an entire class of people (all surgeons are overly aggressive, all pain docs do the right thing, all mid-level are incapable of assessing pain paitients) is being unfair.
