I was considering starting a thread about the Japanese health system, but since I've just found this one I'll post here... neary a year late...
Anyway, my views of the Japanese health system
Preventative medicine
In Japan, the annual full check-up I receive (Ningen Dock) is wonderful. Blood tests, ultra-sound scans, digestive checks... you name it. Cancers and other serious illnesses can be diagnosed at an early stage. It's reassuring, and raises self-awareness of one's body and health.
I've never had a preventative health check in the UK, and I doubt if many others have. Of course, most women get free cancer checks, which is great (men are obviously more expendable, since mens' cancers are ignored.) And there's lots of info available, and advice given. But no actual checks.
Hospital care
I had a small operation in Japan two years ago. I was hospitalized for one week, when the same op in the UK would have taken less than one day. I felt pampered, but was concerned that I was occupying a bed required by somebody with more serious needs than me.
Emergency care
OK I've not need emergency care in Japan yet, but my impression is that it's terrible. In the last few months there must have been a dozen or so cases of patients being denied emergency care by hospital after hospital... with many consequently dying. Emergency departments seem to lack triage. And paramedics don't have the skills or even the authority to administer adequate initial attention. And nobody seems to care!
This of course is in complete contrast to the UK / Europe / America.
Back in the days of HillaryCare being proposed, when America was looking to institute socialized medicine, much attention was given to the Canadian and British models, which by my inadequately informed understanding are both abyssmal failures.
Where did that understanding come from? As I said earlier, preventative medicine in the UK needs improvement, but otherwise health care is excellent, efficient and FREE. Even after-care, such as long term physiotherapy, is completely free.
Waiting lists for non-emergency operations can be long in the UK, but one can opt for a fairly inexpensive (much cheaper than Japan's anyway) private health plan
in addition to the National Health Service. You can have a your op almost immediately in a private hospital. Thus is possible to have the best of both worlds.
