My experiences of UK A&E vs US, Germany, France, Argentina and Dubai (I might have forgotten one or two!) are:
1. Nurses in UK have a jobsworth chip on their shoulders
2. Doctors are good in UK, they don’t overtreat, seem to get it about right
3. A&E v busy (same in US). Other countries’ A&E almost deserted
4. There’s a lot of health tourism in UK. Anyone treated for free, even though foreigners are supposed to pay and the NHS never send bills!
5. People go to A&E for trivial things
6. The British fondness for alcohol doesn’t help
I don’t think throwing more money will help all that much.
Obesity is the major killer (high risk factor in all cancers and CVDs). Also, STDs/STIs are on the rise. For the NHS budget, though, the major killer is the growing lifespan (more precisely, the life expectancy curve rectangularisation, i.e. more and more people will achieve the age of 90 - the newspapers' revelation that we will live to say 150 years of age by 2020 are erroneously calculated from the life expectancy at birth) combined with non-deadly diseases, such as arthritis. The last problem will be partly fixed for some time when the post-war baby boomers die.
