I'm not sure why they exist either.
When I phoned them clearly very ill (but too scared to call 999 due to the hammering people get for calling 999 unnecessarily), I started off ok-ish but deteriorated on the phone
111 person refused to pass the call along to someone medically qualified or to place an automatic call to 999, until I'd answered the questions around my age & ethnicity... which would have be fine except after the 20 mins on the phone jumping through their hoops, my condition had deteriorated massively and I was no longer able to breathe well enough to speak and was slipping into unconsciousness.
As I faded out all I could hear were the ducet tones of the aggressive woman screaming down the phone they she would disconnect my call without any medical help unless I told her whether I was black or not! I remember trying to say cocasian over and over again and then 'help me' when she wouldn't listen... I drifted out knowing I was dying and she wouldn't help me...
Incredibly inappropriate given that A. The medical qs id answered fully were clearly saying 'aortic aneurism in progress' and B. The woman knew I was alone with a small child in the house.
Thank fuck for my friend, who I'd spoken to just before calling 111, who agreed i should err on side of caution and call 111 vs 999. Anyway, my friend panicked when I didn't pick up and called 999, who did spring into action when my symptoms were related to them. Thank fuck.
I'd have died otherwise and my little son would have found me dead when he woke in the night. Making me cry just thinking about it tbh.
I got in contact with the ambulance crew afterwards (to say thanks and give present), and one of them said never to call 111 for anything more than basic healthcare (e.g. UTI's where an out of hours gp can prescribe antibiotics etc ), as they fail at either end of the spectrum by telling people to go to A&E when it's clear to anyone except the computer that there's no need, and by not being able to function when someone is seriously ill / becomes seriously ill on the phone.
