My theory is that if someone suffered malpracticed or some of the other issues that were likely to cause a lawsuit, the person doesn't want to reopen emotional wounds.
I've seen plenty of patients that suffered some form of malpractice. I've encouraged such patients to report the actions of the other doctor to the state medical board. Most of them did not, citing that they didn't want to go back on that painful part of their life.
While the same could be said of any medical profession, with psychiatry, patients have to openly admit to being mentally ill. I think that's the difference. I believe such patients feel even more vulnerable.
I mean if a psychiatrist finds the need to hospitalize a patient, and the patient does not want to be hopitalized...is this not a seed for being sued?
The two biggest causes of lawsuits in psychiatry are one-suicide and two-abandonment. The thing with involuntary hospitalization is in virtually all states, the patient will get a hearing from a court within 72 business hours. A doctor could be sued for malpractice for holding someone against their will, but remember that for the criteria for malpractice to have been done, the standard of care must have been violated, and there has to be measurable damage as a result of that doctor's decisions (among others, but I'm only going to mention the cogent ones here).
The problem here is that within 3 days, most people cannot bring up damages that IMHO courts or the potential plaintiffs would find meaningful. If a guy lost a day at work or even three, no he's likely not going to sue for that even if he was wrongly held. If a guy were held against his will and shouldn't have been hospitalized in the first place, well the same states usually only give doctors a very limited time to decide if that person should've been held bringing up the argument that the request for commitment was reasonable given the limited information. After the 3 days, it's the court's responsibility. If the person was committed, it's the court at fault, not the doctor. Remember, doctors don't commit patients, courts do. Doctors can only ask courts to commit patients. You can't sue the court. You can only appeal if you disagree with their decision. Another factor is involuntary commitment is a multistep process. While a professional such as a psychiatrist could request for a hold, in most states, other people also have to agree with that. E.g. if you're an ER doc and you request a hold, the person is then transferred to psychiatry. Psychiatry could then discharge the patient. In most states, one can only be held after several parties, including the original person who requested the hold, another professional for verification, then the psychiatrist on the unit all have to keep it up.
So if a guy was held for the full 72 hours, and that guy sued the original guy who requested the hold, his defense attorney could bring up that several people continued the hold who agreed with him, strengthening that this act was under the standard of care.
In my current job setting my problem is not keeping patients in but getting them out. Several times I've had patients that were safe for discharge but the court had to discharge them because they were charged with a crime and were put in the hospital for legal reasons. I've had situations where I wrote letters to the court saying the patient was fine for discharge and it's sitting on the desk of a judge who for whatever reason doesn't start reading it till about 3-4 months after it's placed on his or her desk. All the while the guy keeps asking me "why am I not being discharged?"
