"My mum's sudden unexpected death"

My mum visited NGH in March 2013 for what should have been a simple in and out hernia repair. It should only have been day surgery. Whilst in recovery she was still experiencing bleeding from wound so she was admitted for an overnight stay. To cut a long story short she spent 2 nights on Spencer ward and passed away at 5.50am on the third morning. We received a report as part of a standard investigation into sudden unexpected death and the findings of that report are shocking.

The consultant in charge of my mums care had absolutely no idea she was on the ward, therefore potentially affecting her obs. The nurses looking after here were unaware of why they were looking after her. When they found her in bed unresponsive it took them 7 minutes to call the crash team by which time it was too late.

On arriving at the hospital the morning of my mums death and asking the nurse who was supposed to be looking after her what had happened, she proceeded to tell me in great detail. She even used hand motions just to be sure there was no confusion about what had happened and couldn't stop mentioning that between the hours of 2am when my mum got up to go toilet and when they found her at 5.25am she kept ringing the bell but it seems those bells were unanswered. The report then goes on to say that they don't feel with better management the outcome would have been any different.

I'm never going to get my mum back, my daughter has lost her grandmother and NGH don't feel that better management would have made the slightest bit of difference? To me it's laughable.
