People go to A&E, sometimes unnecessarily, because there is no other way to access care. My MIL (who admittedly has a series of complex needs) spent 27 hours waiting in A&E last week with what turned out to be a UTI. We tried everything to get a GP visit for her, but they actually said if it's an infection it needs testing to know which antibiotic to give, and for that she needs to go to A&E. I found this completely astounding but they refused to set her. Whilst waiting in. A&E for the results they put her on penicillin anyway (which surely the GP could have done). I really can't believe that A&E was the best and most sensible route for her to be treated for a UTI, but the GP told us that was the only way. It isn't always the fault of the people showing up there.
Similarly when DD was a baby screaming in pain with acid reflux, the GP said go to A&E there was nothing they could do. We were eventually admitted to paediatrics and she was started on ranitidine (zantac). Again.... Surely A&E shouldn't be the only way to get that, but we were told it was. Again, it isn't always the fault if the people showing up there.
I don't understand what is going wrong in this part of the system, but urgent care needs of this kind are being shunted to A&E, and it's not clear why.
Where I am, other parts of the system are fortunately working well. Both my parents and in laws have had a range of treatments and surgeries recently, some planned some not, and received excellent care.
