Bad idea. If anything, what you need in a hospital is short paths to transfer people from one specialist department to another (or, should the patient be too unstable to transport, to call up the specialists to get down to ER), and you need integrated IT systems to not waste time with data transfer.
Why are they rising so much?
There's a combination of causes... and probably they're also applicable for the US:
- rising costs of energy (electricity, gas)
- decades of underfunding of building construction and maintenance, leading to a massive backlog of issues
- same for IT
- modern machinery (ultrasounds, MRTs, CTs) costs immense amounts of money
- general staff shortages that need to be filled via expensive temp-staffing agencies on one side and cause wage rises for those employees that remain
- as a result of that, beds have to be marked as "inoperative" and they don't generate income, whereas the expenses keep piling up (there finally are reform plans to pay hospitals for providing beds, but it's a ... let's say toxic minefield)
- rising costs of administrative bullshit and legal compliance
- insurances being utterly ridiculous regarding payments, both
In the US, I'd add "more and more people unable to pay", which leads to the cost of care for these people being redistributed to everyone else.
