One can only hope that if this issue arises that it has taken place in a hospital or medical setting where an ill or incompetent person has been taken. This kind of care should be elicited out of love or concern by family or friends.
Often an ill or incompetent person appears to be without control of their normal faculties, where they are unable to recognize their own problem and are found to be at the mercy of others. In a professional medical setting this is recognized and may be related to a medical condition that warrants full evaluation, including a diagnostic screening. And the appropriate intervention.
If a person is of sound mind and is confused, a slow deliberate effort is made to determine the cause. Ideally, a full explanation of this goal to the family or a determined competent close friend. Must include their written consent as the patients advocate, to proceed with the the necessary steps in the patients best interest.
If ethical questions arise in this scenario, it may be best to involve the ethical committee early on to be part of the process. As there may be ongoing risks related to the patients rights. As well as many necessary decisions as they relate to the diagnostic outcome. This move would protect the patient, the family and the health care institution from any questionable issues that may be considered an infringement on the rights of the patient.
It stands to reason in most cases that if the person in need of hospitalization would, if in their right mind, acquiesce and agree to appropriate care. However, this may not be true in some cases. An example might be when religious beliefs are in conflict with care.
Therefore, when a person is unable to speak on their own behalf, the acute care necessary to save a life is administered. Psychiatric conditions , and those conditions where a person is impaired related to drug or alcohol must involve professionals in those areas, and the consent of the patient for their hospitalization. When a person is at risk to harm someone or do harm to themselves. The proof of mental incompetence by at least three physicians is necessary . All other issues surrounding their care must be with the patients full consent or that of a patient advocate.
In the best scenarios a loving family or friends are supportive through out treatment and until their recovery is complete. This is the best outcome of quality care.
