I have not heard that the ABA has softened their stance on this issue. The last I heard was that the ABA reserved the right to withdraw your certification status if you were found to be participating in assisted suicide or lethal injections for convicted criminals. I don't agree with their stance as I think the two are completely separate and that it is overstepping by the ABA (they do not have the same policy for those who participate in abortions). I think the ABA should have no policy on the issue and that it should be left to state medical boards to ensure that the physician is complying with local laws.
With regards to the futile care of the critically ill patient, I believe that compassionate withdrawal of care is the way to go and that we will see a sharp rise in this as we try to deal with rising costs of medical care and how we can better utilize our limited resources. In my opinion, we treat our pets better than we do our family members. We would never allow our pet to suffer for days, weeks, months, or years like we do family members. The problem comes in when people have other motives to hasten death or prolong life (many times driven by monetary gains-they may get a large life insurance settlement if they die or they may continue to get substantial government benefits if they are kept alive). Often times, the financial security of the rest of the family members hinges upon the outcome of the critically ill or slowly dying loved one, and that needs to be reconciled. Another issue is unrealistic expectations of what recovery will look like for their loved one. Many think they will recover and go on to lead a normal productive life like they did previously. The reality, many times, is that they will require 24 hour care, have no idea who they are or where they are, and will live out a miserable existence in a nursing home. The lines are almost always blurred by confounding motives or misconceptions. Each case has its own unique circumstances and it will be a challenge to apply a one size fits all policy. In addition, it is likely that the way we do things today, from an ethical standpoint, will be viewed through a vastly different lense 10, 20, or 50 years from now as cultural norms change.
