Fly by wire
You are correct - it only effects UK doctors. So the advice on this board may well be slanted to overseas care. Far far more worrying is if someone gives advice that flies in the face of medical knowledge or indeed is openly dangerous. From 22 April I will not be able to counter this.
Theoretically I can PM the original poster to say this advice is dangerous, but others may take up the advice.
I accept this risk has always existed but it is bizarre that the GMC whose strap line is 'protecting patients' is imposing new regulations that may not do that
