The figures are from January to November 2019.
843 people over the age of 75 waited over 24 hours to be seen at emergency departments in the midlands in the first eleven months of 2019.
The figures peaked at the Midlands Regional Hospital in Tullamore, with 628 left waiting.
That's followed by 146 in Mullingar and 69 in Portlaoise.
Deputy Brian Stanley, who's a Sinn Féin candidate for Laois-Offaly in the upcoming election, says no sick or injured person should be waiting this long to be treated, least of all elderly citizens.
He says it's unfair on both patients and frontline staff, and capacity needs to be increased urgently:
