Both Sligo and Letterkenny University Hospitals have been ranked among the most overcrowded facilities nationwide for the month of November.
The Irish Nurses and Midwives Organisation has issued a stark warning, stating that this is the worst November on record for hospital overcrowding and has raised particular concern for hospitals in this region.
Letterkenny and Sligo come in third and fourth place in the list of most overcrowded hospitals in the country for this month.
Figures show that a total of 1,108 people waited for a bed at Letterkenny University Hospital over the course of November.
When compared to November of last year, it reflects a slight rise.
However the situation in Sligo University Hospital is arguably worse. This month saw 783 waiting for a bed at the facility, compared with 339 waiting last year.
This reflects in an almost 44% jump in terms of overcrowding, people waiting on trolleys and in overflow areas.
Nationally, over 12,624 people have been without beds in Irish hospitals this month.
In a statement, INMO General Secretary, Phil Ní Sheaghdha acknowledged the acute problems with hospital overcrowding in the Midwest and along the Western seaboard.
The INMO says its members expect the HSE and the Government to treat this issue as the emergency it is and meet with them to address the issues they have raised as immediately necessary to maintain safe care this winter.
