University Hospital Limerick has the highest overcrowding levels in the country today with 69 patients waiting.

The latest figures from the Irish Nurses and Midwives Organisation show there are 492 patients waiting in emergency departments, or on wards for admission to a bed.

Other hospitals with high levels of overcrowding are Cork University Hospital with 43 patients waiting and Letterkenny University Hospital with 42.

While the Limerick figures are very high at 69, it experienced a record 80 patients waiting in March.

The HSE's TrolleyGar figures put the number of patients waiting for admission in emergency departments at 358.

Their figures do not count patients waiting on wards.

Both the INMO and HSE figures show an overall increase in overcrowding today, compared with the same day last year.
