The emergency department, including the collaborative emergency centre, at Western Hospital in Alberton, P.E.I., will be closed for 12 hours beginning on Sunday at 8 p.m.
Health P.E.I. says the closure is necessary because of a "temporary lack of nursing coverage." Closures at the ER due to lack of doctors or nurses has not been a rare occurrence over the last several years.
The agency advises anyone with emergency medical needs to call 911 or seek emergency services if they have discomfort or tightness in the chest, unusual shortness of breath, abdominal pain, prolonged and persistent headache or dizziness or an injury that may require stitches or involve a broken bone.
The emergency department will resume Monday morning at 8 a.m.
The nearest emergency department for those in the area is in Summerside, about 65 kilometres away.
Parents should also seek help for a child with prolonged diarrhea or vomiting, or for a baby under six months with a fever of 38 C or higher.
Officials also reminded Islanders to call 811 if they have any health concerns or need immediate health information.
