I agree that there is a role for PAs working alongside doctors, supporting their workload, but I am not convinced they are necessarily trained for the job some of them are doing e.g. seeing undifferentiated patients and replacing doctors in hospital rotas. This is the issue.
Whether you like it or not, doctors are more qualified than PAs, and can do more than PAs. This is just a fact, and the existence of some poor doctors and some brilliant PAs does not negate that.
And you say that doctors are different from, not better than PAs, which is curious. Clearly being a doctor doesn’t make a person a better human being than a PA, but it does make them better qualified to triage, examine, investigate, diagnose and treat patients, and also allows them to undertake tasks such as prescribing which PAs explicitly cannot (although it seems, sometimes do). What tasks can PAs do that doctors can’t?
This is not elitist or “professional protectionism” (a phrase I’ve heard in the discussion of the consultation around pharmacy supervision, which is a whole other pile of nonsense for another thread). It’s just reality. We actually do need experts.
