I don't think we could say with absolute conviction in every single case. As I was mentioning before, in hospitals, in terms of the issues of what constitutes valid consent, what is truly voluntary consent, and when is the person giving the consent really truly capable of giving this consent, these are very complicated issues.
Where there are difficult cases, they are often the subject of discussion by a provider with authorities in a health care institution, but that's not the same thing as what you're alluding to, which is some sort of system where every problematic consent case is somehow or other logged somewhere, and somebody could look at all of those consent situations. But there is, for reasons of legal liability, a lot of interest on the part of providers in being certain that what they believe has been freely given and informed consent is in fact the circumstance.
