I agree a lot of the examples here of how 111 failed them are situations when the poster should have gone straight to A&E. You need to use some common sense, do you think without 111 in your case you would have rung 999/gone to A&E straight away? Or do you think actually you would have waited probably as long as you did and ended up in a&e anyway?
Of course 111 is not ideal, and yes it would be better to have a system of emergency GPS and A&E. Unfortunately we do not have the capacity to do this, because the NHS is underfunded.
What you are saying is true OP, but you are demonizing the wrong people. You can't just scrap 111 without pumping masses of money into the NHS, without training more GPS which takes years.
You also can't really say 5 children have died as a result of 111 when you don't know how many people would have died without 111. Yes it is horrible that 5 children died, but there will be parents who wouldn't have taken their child to A&E who did because of 111.
111 is a useful system if you are unsure about where is appropriate, if it is obvious A&E is necessary then you not need to ring 111.
