"Concerned over poor nursing care for my partner"

My partner was on I ward at the Royal Hallamshire Hospital for 2 days following a vitreo-retinal operation. We feel the after nurse care was very, very poor. No nurse came to check on her for hours. She asked for pain killers which took two hours to arrive. She also asked for something to eat, as she is diabetic and was starving. Also after the operation, when she was on the ward to recover, no nurses came to check her blood sugar and ask how she was. That was from 12pm on the Friday to 3pm on the Saturday. In my opinion she could have died and no body would have known. This is unacceptable.
