95% can absolutely be done by someone with far less training than a medical doctor, but the real job of being a doctor is having the expertise and experience to spot the other 5% and sometimes to respond quickly enough with extreme skill to prevent medical catastrophe.
I want to see far more involvement in direct patient interaction happen with nurse practitioners and physician assistants, with doctors supervising cases to ensure no one falls through the cracks. I'd love to see more specialization of NPs and PAs to handle cases that are complex but routine within a speciality.
The problem is a lack of respect for NPs and PAs, with many patients only wanting to see a doctor. We need to promote these occupations as the highly trained and licensed professionals that they are and make sure they get the respect they deserve.
