HIV/AIDS? You are talking about a protected class there. That will never be rationed.
Seriously, the problem with "end-of-life" care decisions is that a lot of care can be end-of-life care if you deny it. Juvenile cancer treatment, a new born that needs a respirator, a 50 year old that need a heart bypass. All you have to do is make the waiting list long enough. Once you start making those decisions where do you stop. The answer is that you don't.
My grandfather had a bypass/valve replacement done when he was 75. Pretty sketchy, but he lived 4 more years before being felled by cancer. A lot of his health issues were due to war wounds from WWII. His legs were all messed up and he wore two different sized shoes. When they start rationing care to guys like him they will basically saying 'thanks for all the work, paying taxes, bleeding for your country, but we don't need you anymore.'
I don't want to live in a country like that.
See, per HIV/AIDS, I don’t think a complication has to be classified as such. And there are many, if you’ve ever known someone with it. It could be called something else, like terminal or serious, or <5 year life span or some such.
