Sligo University Hospital is the third most overcrowded hospital in Ireland today, with 45 patients waiting for a bed. While Letterkenny University Hospital is the fourth highest with 38 patients on trolleys.
In total, there are 651 people, including 14 children, waiting for beds in hospitals around the country this afternoon.
The INMO General Secretary Phil Ní Sheaghdha has labelled the overcrowding as "totally out of control", and is concerned the system will be "completely overwhelmed" by the end of the Easter Bank Holiday weekend.
