Any suggestions for coping or assisting a confused and delusional individual?

posted originally for help in conversation w/confused/disoriented individual--the situation has increased in severity the individual is living her life thru each visit of telephone call. she is still being treated as an 'in-patient' however, everyday brings a new scenario. She has stated on occasion where she is and associates the hospital as place the event is incurring.I.E. she recently mentioned she was in our parish facility and was attending a women's club event. The fact of the matter is she was still in the hospital. Can anyone offer tips/suggestions that I may use.
Thank You
