"I don't think it's appropriate for people of this age to be dealing with sick, frightened and stressed members of the public"
My DD worked for Boots as a healtcare assistant from 16 - she took her NVQ2 while working and dealt with sick, frightened and stressed members of the public every day. ANd gave them medical advice. Its not rocket science.
I would love to see stats on how many people are told to take plenty of fluids, a couple of paracetamol and see their pharmacist in the morning if they dont feel better, because I suspect the majority of people calling 111 are the worried well who just need a bit or reassurance.
