The number of people left without a bed after being admitted to University Hospital Limerick is twice that of any other facility in the country today.
According to the Irish Nurses and Midwives Organisation there are 106 patients on trolleys at the hospital which serves North Tipp, Limerick and Clare.
This compares to 53 at both University Hospital Galway and Cork University Hospital.
Nationally 420 people are being cared for on trolleys which means frontline staff at UHL are caring for quarter of the total numbers without a bed.
According to the nursing union there is one patient on a trolley at TUH in Clonmel with no overcrowding at Nenagh General.
