Over 10 thousand people were waiting on trolleys in hospitals last month - the worst April on record.
The figures from the Irish Nurses and Midwives Organisation show an 8 per cent increase on April 2018 and a 125 percent increase on the same month in 2006 when records began.
The worst affected hospital for overcrowding was University Hospital Limerick with 1,026 patients followed by Cork, while University Hospital Galway had the third-highest trolley numbers with 638 people waiting on trolleys during the month of April.
That's a four-fold increase at the Galway Hospital since 2006 when records began.
At Mayo University Hospital 272 patients spend time on trolleys last month, while 446 patients were on trolleys at Sligo University Hospital.
