The man received an initial assessment by a member of nursing staff on arrival at the IAU. He was then categorised and the unit was reportedly 'under pressure' at the time.
How old was the man? Did his age have an impact on the time he waited?
Health status can change quickly in some patients but a six hour wait on a trolley and in a corridor is a step back to the bad old days of a few decades ago when this happened all too often.
An expensive new hospital with all the modern technology needed to provide health care is not much good if there are staff shortages and demoralised staff. That may or may not have been the case Tuesday at the Queen Elizabeth University Hospital.
GGC has denied patients being given blood transfusions and treatment in corridors reported in the media.
A statement from NHS GGC said the man "sadly passed away in the early hours of Tuesday morning" after receiving "an initial assessment by a member of nursing staff on arrival at the IAU".
Emergency departments however should be able to cope with extra patients; that is after all their mission.
Assessment Units are now a feature of many N.H.S. hospitals and generally work well.
Patients however may find their bed is a type of trolley and not the most comfortable. This is because the ward is not designed to be the actual ward destination for patients. Instead patients are assessed, discharged or moved on to the appropriate ward with a normal hospital bed provided; second hand personal experience has taught me that does not always happen.
When my husband was admitted to our local AAU a few years back with suspected heart trouble that turned out to be a gallbladder which needed removing the level of care was exceptionally good.
However he was a patient on the Assessment Unit for too many days sleeping on one of those trolleys and as he is over 6ft 1 inch tall it was far from a comfortable stay.
