My original post was born out of indignation and frustration on Tuesday, after the day case surgery that DH attended had 66% DNAs. I don't know that much about it as I'm not involved professionally, so it's based on my experience and what HCPs have said to me. Obviously, I have read the whole thread (only polite). Because we only have one big general hospital within 50 miles, it's the only one I know, but I've had breast cancer and auto-immune ezcema over the last 18 months, and DH has a 15 year history of heart problems, plus we've recently had to assist the residental care unit organising appointments for DMIL (93 with dementia), until she fell and fractured her femur, so I have seen a lot of it recently!
It's well-evidenced that all hospitals' appointment systems are not the same, and no two departments within the same hospital communicate with any of the rest, but either we have been incredibly lucky or the hospital is actually organised enough to send appointment letters out several weeks ahead, followed by text reminders and a live confirmation phone call to check that the patient is attending. The timing often runs late, but sometimes a clinic speeds up too. I can see how difficult transport might be if you can't or don't drive, and that last-minute appointments are a PITA if you work shifts or have an unhelpful employer.
However, as hospitals are for ill people, most people will feel stressed or worried about what's happening to them/the patient.
My experience of mutualised French medicine is that it works better for patients, because it's so much less centralised and the patient is more in control of when and where to seek treatment. And now, the cost is not much higher than the NHS while the outcomes are significantly better. I lived in the US too, and we all know that healthcare there can be either brilliant, if you have solid medical benefits, or dreadful if not.
My instinct says that fining DNAs isn't the right approach and would quickly turn into a bureaucratic collection nightmare. But failures to attend need some form of sanction. I just don't know what would be fair. That's why I asked what the hive thought.
