"lady with dementia sent home alone"

82 year old with dementia admitted to a and e at Grantham. The lady having a panic attack 6am. Seen by doctor and deemed physically fit at 10 am. Her son spoke with a nurse at 7am The nurse said she would update him. Sadly the lady was sent home alone. Her son received no call. She was frightened, alone. Her son called the hospital at 12 noon to find this out. Not good care. A bit thoughtless leading to a 82 year old lady to be frightened.
