The Irish Nurses and Midwives Organisation (INMO) have said the overcrowding at the nations hospitals this November was the worst on record.
In a statement released today, the organisation said there were a total of 9,679 patients waiting for a bed last month.
It is understood that University Hospital Limerick was the worst affected with over 1,071 patients waiting for a bed.
Cork University Hospital was second on the list with 932 patients on trolleys, whilst University Hospital Galway were third with 676.
Meanwhile there were five hospitals in total with over 500 people waiting on trolleys.
The INMO say the ever growing trolley crisis is the result of low staffing levels which is caused by low pay levels.
