Thank you for clarifying your question. It is often hard to have a discussion in this type of format regarding complicated legal issues. Thank you for bearing with me and I will endeavour to answer your question.
1. He has been placed in a psychiatric wing of a hospital for a 72 hour voluntary commitment. 36 hours have passed so far and he has not been seen by the psychiatrist to your knowledge.
Has the psychiatrist done anything in breach of his/her legal responsibilities as a doctor?
Answer: Not yet. A 72 hour voluntary commitment only requires that he be placed under the supervision of a psychiatrist. That means that as long as the staff is watching him and he does not have any episodes which require emergency treatment by the psychiatrist, then no standard of care has been violated. However, if the psychiatrist fails to evaluate him at all during the 72 hour period, then there may be two potential claims: 1) against the psychiatrist for malpractice, and 2) against the hospital for breach of contract
The fact that the psychiatrist has not come to treat him since he has been in is not illegal. In fact, the psychiatrist could claim that a proper evaluation could not be performed until after the 72 hour period has passed, especially if this case involves drug abuse
or requires sedation. Of course, you haven't answered my questions regarding the nature of his commitment so I'm not sure how else to advise you.
What you should realize though is that neither you nor your friend who is the mother have any rights whatsoever in this situation. He is over the age of 21 and has entered the hospital voluntarily. The duty of the hospital and psychiatrist are owed to him only, not to you and not to his mother.
I see you have left me a negative rating. If you are not satisfied with my service, instead of rating me poorly, you could let me know. This is probably also what you should do with the hospital. If you demand that the hospital provide treatment then perhaps you will get them to order the psychiatrist to either make an evaluation or communicate with you about it.
If you are not satisfied with this response, let me know, and I will opt out and let another expert try and answer your questions to your satisfaction.
