Management at Cork University Hospital has warned of delays for patients attending its emergency department today, with 200 people expected to present for treatment and for review throughout the day.
A hospital spokesperson said 420 patients had attended the emergency department between Friday and Sunday. Of these, 165 required admission.
The spokesperson described the hospital's emergency department as "extremely busy".
A count by the Irish Nurses and Midwives Organisation at 8am this morning put the number of patients on trolleys in the hospital's emergency department at 24.
A further 15 patients were on trolleys in hospital wards.
Nationally, the INMO says, there were 445 people on trolleys in the country's acute hospitals this morning, as over-crowding problems persist throughout the hospital system.
Management at Cork University Hospital is appealing to people to explore all other options available to them - including their GP - prior to attending their emergency department unless their need is urgent.
