Thank you annepl.
Someone mentioned toothache upthread. There is no pain like it, and often no emergency dentist. An untreated abscess can be a real emergency, as can other things that have gone untreated because people can't get GP appointments.
It may be the case that private services are available, but I would have no idea how to access them, and in any case, where does that leave people without the money to pay?
I am lucky enough not to have needed A&E for myself (once or twice for my children over the years), so I am not making these points to justify anything. I think that the whole thing is like a jigsaw, and cutbacks in one area impact on others, with A&E being the fallback. At least people know where it is, and that they will be seen.
Whatever 'should' happen, that is the bottom line. We need to have somewhere to go to get medical advice and/or treatment when we need it. How we organise that is a separate debate, but as it is, I really don't think that people always know what to do in non-emergency but urgent situations.
