I work in the health industry very often in the private sector. I can confidently say that there are many older patients getting arduous treatments for diseases they will not survive.
So their remaining months are spent tubed up in a hospital vs palliative care at home.
Often this is done at the adult kids request - "save my mom/dad". I've seen doctors fear mongering some people into treatment they cannot afford or survive.
Then I've seen other doctors try and talk people's family out of treatment as its extremely debilitating.
