If he doesn't eat fast enough, they feed him and most times they just flat out feed him ... personally, I think that they have made him "lazy" ... our stance would be ... put that food in your mouth yourself or go hungry. He is still wearing a diaper because he will forget to ask to go to the bathroom ... I would have thought that they would take the same approach one would take while potty training a toddler ... ask every hour or more if he has to go to the bathroom or just get him up every hour and walk him to the bathroom and see if he will go.
The average staff member is only going to do what they have to; the bare minimum. From the way it sounds he has been combative (which can further alienate the staff) and they are keeping him sedated because of it. The only way anything is going to improve is if the administration lights a fire under the routine staff to do go the extra step with documentation as proof.
To be blunt, the only way anything will change is if his family (preferably a Power of Attorney) complains to the administration. They do need to keep their complaints as a list of defined events and they also need to season them with future realistic goals. If no change happens after a month or two, they need to consider moving him to a facility that may be more successful or at least more attentive to his needs.
For goals, I'd push for a weekly list. For example;
---------------------
Week one: patient will feed himself lunch (I'm guessing he is most coherent at this time). If necessary, foods he can pick up with his hands (like sandwiches) will be provided. He will be allowed to take as long as he needs to finish his meal, provided he has the ability to finish.
Week two: He will continue to feed himself lunch, with a few meals consisting of articles he has to use silverware for (like pasta/shells). He will begin to dress his upper torso in the mornings with assistance.
-------------------
Granted, I don't know where he is at as far as his functioning. Regardless, make those goals reasonable and known to the family, the staff, and most of all to Morpheus.
