Hi there,
Sorry to hear you both are going through such a rough time.
Have you asked at the hospital to speak with her doctor(s) about her diagnosis, treatment and prognosis?
I know (from personal experience) a doctor will inform a spouse on the other spouse's progress, you need to call the doctor or have someone at the nurses desk make this contact.
Also it is beneficial if both you can consult with the doctor about possible caregiver support, many hospitals have counsellors/educational support groups for the friends and families of loved ones suffering from mental disorders.
I am not a legal person, but I am sure when you are a spouse or parent of someone in the hospital the doctor(s) have to at least inform you of any progress/no progress and what needs to be done when the patient does eventually come home (which can be a major transition in its self) cause there often needs to be some changes made at home, seeing where things went wrong or can get better.
I think if you consult with hospital staff where your wife is they will help give you some direction as to who to talk to and/or support. Also, I know in order to have insurance cover a patient's stay in a psych ward the patient needs to be discharged by the pdoc otherwise if a voluntarily admiitted patient decides to leave the hospital and in most cases they can sign themselves out, insurance will not pay for their stay there. Just passing some info about this in case you do not already know that. This has to be difficult for you, but keep in mind it is hell for her too. You'll both need to work with the doctor or a counsellor on how both of you will be dealing with future outcome. Not only does the patient need to change or help change (through medication intervention) the person who is either the caregiver and/or spouse may need to make some changes and be open to being more understanding, that is where either a support team or a consult with her doc can be most beneficial, helping to educate the patient's family of things they may encounter and/or never knew about various mental disorders. I wish you lots of luck with this and I hope my "2 cents" was of some teeny help to you.
I hope things will come about soon, and do not be afraid of being assertive with the medical staff on getting info on your wife.
Please take care,
"darkeyes"
