"My nan was treated for kidney ..."

What could be improved

My nan was treated for kidney cancer in Watford, the operation went well and was on the road to recovery. However she was struck down but a infection from there her health declined. She was moved into a private room and just seemed to have been forgotten about, I went to visit her at dinner time and everyone else had been fed apart from her because 'they didn't think there was anyone in the room'. When I asked where her food was staff were very rude, the hospital wasn't particularly clean either, my nan sadly died from her infection. So I think its the staffs attitude that needs reviewing and the cleanliness of the wards.
