My mother cannot discharge herself... can she?

My mother is in a skilled nursing facility, wheelchair bound.

I am as of yet waiting to talk to the Discharge Planner to get any sort of an update on her situation, other than the version she is relaying to me (which is unreliable at best).

Well, my mother just called me and said she spoke to my brother's wife, who is "getting her a wheelchair", and then "she is going to have my brother come and pick her up and take her to a motel in Fullerton where she will stay for four days". Not kidding.

I still haven’t gotten a call back from the Discharge Planner, who I have tried to call several times.

I told my mother in no uncertain terms she cannot come back to my house wheelchair bound as she is unsafe. I said it as kindly and compassionately as possible. She unloaded on me with a litany of hostility, and then hung up.

I’ve tried to call my brother, no response. I don’t know what else to do, but wait to talk to the Discharge Planner.

There is no way she can discharge herself, can she?
