He eats in a dining room which is where most of the incidents are happening and it's a problem because no one is directly paying attention to him and anytime a nurse sees someone fall and possibly hit their head, they have to call an ambulance and send them to the ER. Most of the time it hasn't been necessary and it's expensive! He tends to fall asleep easily and then leans of course but the chairs have thin arms and he falls out easy. He also has dementia so he wouldn't remember to always bring some sort of device with him to meals. Any ideas on what I can do to help?
