I've had the unpleasant opportunities to watch a number of relatives and neighbors spend their last months tortured by the medical profession. I really can't find a more appropriate word, even though everyone involved means well. It is hard for both families and medical providers to assert that sometimes the best thing that can be done is nothing.
Assisted suicide is only part of the issue, but perhaps it is where the conversation needs to begin. It is an option exercised millions of times each day on every animal except Humans as being more humane. However the conversation needs to continue from that point. I think of my 90 year old neighbor who had cancer. A type that if he was 30 surgery and treatment would have cured. One doctor wanted to operate, the other did not saying he would not make it. The family, ever hopeful, pushed for the surgery. What transpired after that was 5 weeks of torture. He did not do well in the surgery. Doped up in a hospital bed his wounds became infected, requiring another surgery. That necessitated a feeding tube, which then due to his poor condition also was infected. Finally after 5 weeks he was barely well enough to go home with 24x7 nurse care where he was able to somewhat peacefully pass away a few days later. The options here were all bleak, spend 3-4 months dying of painful cancer. Spend 5 weeks in the hospital undergoing multiple surgeries, doped up beyond belief. Assisted suicide, at the right time, might have been a good option. I have no idea what bills the family was left with as a result of all of this treatment, but I bet they added further pain after the fact.
End of life care is not a simple decision. Everyone involved, patient, family, doctors needs to realize we can't extend life forever. They need to realize that sometimes doing nothing is a better option than doing something, or that sometimes the something to do is to go ahead and choose to end life on the patients terms.
While for me this is 99.99% a moral and ethical issue, it is also a cost issue. For many patients more money is spent on their final month of medical care than in their entire life, because of these sort of heroic measures that lead to tragic outcomes. Fortunately I don't think saving money needs to be the primary concern here, but rather it can be a happy accident of doing the morally right thing.
