Believing unaccountable decisions placed in the hands of powerful doctors without recourse results in a professional suicide assessment is not what actually happens. You may be detained for no reason and have no recourse. They may pump drugs into you.
Come up with a reasonable objective bar to pass before subjecting someone to confinement and medical treatment against their will. Right now police are all too willing to basically arrest someone off of some nebulous accusation. It should be treated no different than the standard of proof for an arrest and should face the same repercussions if done wrongly, both for police and an accuser.
Make it contingent on prompt medical evaluation. The current timeframes for involuntary commitment in certain states can leave people confined on a Friday afternoon and waiting to be evaluated until Monday morning. If it's urgent enough for involuntary confinement it's urgent enough to have a medical professional oncall for prompt evaluation.
The medical necessity of all involuntary medical treatment should have to be substantiated in front of a judge, even if the patient is released before statutory deadlines would have required a judge to approve continued involuntary commitment. The medical facility should have to explain their actions e.g. "On Feb 12th at 5:12AM patient started scratching the skin off of their left arm (Exhibit A) which necessitated the administration of 10 mg of Midazolam intramuscularly". Any medication should also be limited to the shortest duration feasible until a court order is issued, no depot injections of Haldol that will last a month.
No financial liability for the patient. The state doesn't have to foot the bill for all of it, you could mandate that insurance picks up the tab and leave the state to pay for only the uninsured. It's profoundly unjust to not only deprive someone their bodily autonomy but also saddle them with a mountain of debt with no recourse even if the involuntary commitment turned out to be unjustified. If it came out of municipal budgets maybe police departments would be more diligent about making sure that involuntary commitment was necessary instead of using it like a blunt tool to pawn off a tiresome person onto someone else.
