@Grivusangel -- Gosh, that's awful the hospital didn't offer patient sitting. It was great when my dad broke his leg. He was loopy from the surgery too, and the hospital decided he needed a sitter rather than one of us. That way, if he did get up and fall, someone who knows how to do it could help him up right away.
I think every hospital ought to offer this service, and especially for any patients who are a fall risk. All the bed alarms in the world won't deter someone who is determined to get out of that bed!
