The GMC has said that the scope of practice should be left to the Royal colleges.
The Royal Colleges (being populated by doctors of course) have largely said no thanks: the scope should be set by the GMC.
There is now a long list of groups who broadly oppose the use of PAs in practice. I do not in the main take much notice of the media or news but by my count at least, this appears to include the Royal college of General practitioners, Royal college of Paediatrics and Child Health, Royal college of Psychiatry and the Royal college of Radiologists. There may well be others, I am sure someone else knows more than me.
The Physician Assistant role in the United States is a very different role in which people are highly trained, highly skilled and very well remunerated.
Like it or not, it seems the government want around 10,000 of these roles in the NHS. I believe the money should instead be used to train up and pay experienced nurses more for being nurses and also open perhaps a band 4/5 position for the most senior healthcare assistants. The NHS perpetually struggles with retaining it's most skilled and experienced nurses and HCAs and the whole system would run far smoother if these were retained and individually invested in in my view.
