question if medical workers have the right to save someone's life against his will?
that is a medical-legal question, encountered regularly by front line emergency workers. Hence, the dnr and goc and other similar medical-legal paperwork. It's actually a relief when someone has thought about the care they want & don't want, and have taken the time to complete the paperwork defining their choices. With those legal papers, we can legally do what
you want. Without those papers, our hands are medically, ethically, and
legally tied, and we are bound to err on the of caution and provide the highest level of care possible.
s it always justified to force people into treatment who are a danger to themselves? Doesn't that take away the right of informed consent? And who and how is this determined?
Actually yes, if someone is a danger to themselves or others then they are no longer mentally competent to make rational decisions. Someone who is not mentally competent, by definition cannot make informed consent for treatment or anything else. This is also a medical-legal issue. The decision is a combination of medical and law enforcement, and requires both under the Mental Health Act. Being "arrested" under the MHA isn't actually an arrest at all, as there is no criminality involved. This is a preventative emergency measure, designed to get the person to medical care, and back to a state where they are no longer a danger, are mentally competent, and can make informed consent. It's not actually a case of "help, help, I'm being repressed" when treatment is enforced against your will here, though it may feel like it in the moment (and keep in mind your brain is in serious crisis here, and incapable of understanding what is happening).
It's been my personal experience, that there is none or very minimal use of physical force by LEO's and medics in the majority of MHA "arrests", because we work really hard to de-escalate verbally first, and use of force is reserved for those who pose serious and immediate threat who cannot de-escalate verbally.
People who are mentally competent and not a danger to self or others, are absolutely free to make their own choices, both right and wrong, and enjoy the consequences of both.
