Indeed I would go further. They are control freaks and you effectively have no rights in a hospital. Do it their way or else. Or else they call security which always takes their side; and if a child is involved they can immediately issue an opinion by a doctor that the child is at risk -- merely at risk of abuse, and then the child is THEIRS. Try to leave or stand on any of your so-called rights, and you will be taught an unforgettable lesson.
The only measure that might possibly work is to announce that you will not pay the bill if they do not let you leave. But you have to say it nicely to somebody way up on the food chain.
