November was the worst month on record for hospital overcrowding, according to the Irish Nurses and Midwives Organisation.

It says University Hospital Limerick was one of the worst hit with 1 thousand and seventy one patients on trolleys in November, twice the eqivalent of the county's total bed capacity.
Five other hospitals had over 5 hundred patients on trolleys in Cork, Galway, Letterkenny, Tallaght and Tullamore.
