They pretty much have already... You rarely see a physician on a first contact. You go through a gauntlet of physician assistants, advanced practice nurses, before you are advance to a board certified medical doctor... usually from overseas.
I typically see my nurse every 3 months and the doctor, from Nigeria, every 6 months. It’s been this way for several years. And to tell the truth, I’m okay with it. My nurse is great. And I like my doctor.
If I go into the emergency facility I usually see a PA.
