What happens if someone needs psychiatric treatment, and they are either unaware of the need, refusing treatment, or not able to make an informed decision?
All states have a method or way of having someone admitted against their will. And, this is one area that Virginia does well. Some states allow any medical doctor to sign someone in...other states extend that to licensed social workers and other licensed counselors.
In Virgina, a person must be evaluated by a representative of the community services board. Each board has an emergency services unit that is responsible for performing the evaluations. Interestingly, none are medical doctors; in fact, some who were grandfathered in have bachelor degrees. About 12 years or so ago the Commonwealth established a certification system. Now an evaluator is required to have a masters degree and go through a not difficult certification process.
Why is this system better than most? Even though these folks are aware of the potential liability in what they do, they are not driven by it. Medical doctors are always aware of the potential to be sued for their actions or lack of acting. The emergency services' worker often time acts as an advocate for the person who everyone is saying needs to be detained. Their job is to look for the least restrictive alternative to detaining someone.
Routinely emergency room doctors and psychiatrists ask for patients to be screened. Their motivations are usually wanting someone else to be the one who makes the decision as to whether or not a person will be allowed to go home.
The typical request is sort of like this, "I don't feel comfortable with discharging them."
