The NHS is the system in the UK. Here we pay National Insurance Contributions. So, no-one should be "uninsured". It's pretty clear that successive governments haven't done a very good job of managing the Health Service, so perhaps the time has come to take a look at other ways of doing things. Remember too that much of the business of government these days is carried out by so-called "Agencies". Most (if not all) of which are actually private companies under contract to the government.
I have personal experience of involvement in Operations and Maintenance contracts at government hospitals overseas. I'm not saying that it's necessarily the answer to all the NHS's problems, but I do believe that it should be considered.
All of which has absolutely nothing to do with IPEM Registration!
