Last month saw hospital overcrowding hit record highs.
Latest figures released by the INMO show 10,229 people waited on a bed at hospitals across the country, up 8% on figures from 2018 - making it the worst-ever April.
Among the patients were 106 children.
Last month saw over 10,200 admitted patients waiting on beds at hospitals across the country, up 8% from the same period the previous year and 125% since records began in 2006.
At Letterkenny University Hospital there were 420 patients awaiting a bed there in April and increase of 65% from the previous year and up significantly from 2007 when just 25 people were awaiting admission to the hospital.
The most overcrowded hospitals in Ireland last month were; University Hospital Limerick, Cork University Hospital, University Hospital Galway, South Tipperary General Hospital and Tallaght University Hospital.
INMO general secretary Phil Ni Sheaghdha says the crisis is without question worsening as this is the second month so far this year where over 10,000 patients have been forced to wait without a bed.
