I’ve used the 111 service a few times, and for me the situation has been dealt with appropriately.
I called for MIL who had Alzheimer’s and suddenly became doubled over in pain. Due to the Alzheimer’s she couldn’t explain what was wrong. It turned out she was quiet badly impacted and in need of medication.
Called for FIL who turned out to be having a stroke. He very nearly got diagnosed with a water infection and fobbed off as other than confusion wasn’t presenting with typical stroke symptoms. Amazingly somehow FIL perked when the ambulance crew arrived and I momentarily worried I may have over reacted but luckily he was whisked off to hospital where he received excellent care.
DD2 had an incident at school during a swimming lesson, went under the water and had to be fished out. Was only told when I collected her, they said she had been coughing as had swallowed a fair bit of water. Having not seen the incident myself and given by the time I got her home and later that evening she was still coughing and wheezing I became concerned about secondary drowning. DD was checked over and monitored and while she turned out to be fine, I’m so glad she was seen.
Both my elder DD’s were referred to hospital as babies when they were unwell with viruses that caused dehydration. Though as far as babies go I think the service airs on the side of better safe than sorry.
All that being said I would not hesitate for a moment to disregard 111 if I felt the situation to be more serious than they believed. I would easily do this for my children or another person however, I think I would struggle to do this for myself. Without another person to advocate for me I think I would be easily fobbed off and worried about wasting time if 111 didn’t think it was serious.
It’s a double edged sword, could be good at reducing needless A&E trips but could just as easily miss situations that don’t necessarily appear acute over the phone but need medical intervention. Sometimes there is no way to correctly assess the situation over the phone and relies on the correct questions being asked and the correct answers being given and sometimes that’s much harder than you might think.
