Most states recognize PAs, but this is very different. Most of the PAs out there are trained at US programs that specifically train them to be physician extenders. They have to be accepted at these programs, and go through the training. This Missouri program sounds like it will allow non-US trained docs to skip US residency training and go straight to work as PAs. It removes a US training requirement entirely.
The article states that they have to speak English. Doesn’t that preclude your concerns?
PAs have 2 years of training after college with no residency or other focused clinical training yet most insurances and administrators think they are as good as my 4 years of medical school and 3 years of residency. Better in fact because they are cheaper. Just about any medical school graduate will have twice the training and experience of a PA. If the want to work as PAs I don’t have a problem with it. Knowing the creep in regulation however I’m sure that soon enough they will be licensed as full physicians. The difference is they will never be board certified
