There are 61 patients waiting on trolleys at University Hospital Galway today, according to the Irish Nurses and Midwives Organisation (INMO).
It is the second most overcrowded hospital in the State after University Hospital Limerick, where 69 patients are waiting for a bed.
The figures show that Portiuncula Hospital in Ballinasloe has no patients on trolleys – one of only six hospitals across the country.
Nationally, 431 people are waiting to be admitted to a ward with a bed and over 400 people have been on trolleys each day this week.
The INMO has repeatedly called for action to tackle overcrowding in Irish hospitals, with the organisation saying that we are in for a very bleak winter which will see nurses and patients in extremely unsafe circumstances.
