I think a bigger issue is hospitals illegally detaining people.
I see about one of these stories every few weeks.
One I read a couple of days ago: Guy being detained in Phuket hospital, medicated, not allowed access to his phone, not allowed to leave until bill (around ฿ 30,000) paid. However the bill increases each day which is a bit of a catch 22.
He was actually reported to police as missing. Of course since he is not allowed phone access he is going to be unreachable (missing) by family and friends.
I used to visit the wards regularly to have a procedure done and they are locked. To open the door the nurse needs to touch her bracelet to a hidden point inside the wall next to the door to unlock it.
