The full capacity protocol has been implemented at the Emergency Department of Letterkenny University Hospital where significant numbers of patients await admission to the hospital.
All efforts continue to be made to identify patients who are appropriate for discharge.
Management at the hospital would like to advise people who are attending the Emergency Department at Letterkenny University Hospital that they can expect delays.
A statement reads: "We would like to remind the public that we encourage them to attend the Emergency Department only in the case of real emergencies and they should contact their GP or GP Out-of-Hours service in the first instance."
Letterkenny University Hospital again apologises to all patients and their families for any distress caused as a result of these delays.
