Cork University Hospital was the second most overcrowded hospital in the country for the month of November.
That's according to the Irish Nurses and Midwives Organisation who say it was the worst November on record for hospital overcrowding.
1,334 patients were treated on trolleys at CUH during the month, with nursing staff describing the situation as "chaotic" as they struggle to provide safe care.
Concerns have been raised over the high number of children admitted to hospitals without a bed. with the INMO revealing that 563 children were without a bed in hospitals nationally last month.
The Union says children's hospitals are experiencing severe staffing shortages with up to 45% staffing deficits in some sites, and long-standing vacancies in nurse manager roles.
Colm Porter of the INMO in Cork has long been highlighting the overcrowding situation at the city's two emergency hospitals and calling for action to be taken.
Speaking to RedFM News, he says the HSE needs to focus on recruitment, retention, accommodation and capacity in the hospital system as a matter of urgency.
