The public are being urged only turn up at A&E departments at Warrington and Whiston Hospitals for genuine emergencies only.
Health chiefs say the recent blast of snow and ice from the “Beast from East” as well as an increase in flu cases has resulted in a rise in hospital admissions, putting pressure on an already busy service.
They are asking people to attend accident and emergency departments in life-threatening circumstances only and to use alternative services for all other illnesses and injuries.
Dr Gary O’Hare, clinical lead for urgent care, said: “Our priority is to ensure that people who need urgent and emergency care get it.
“It is extremely important for patients and their families to work with our staff and as soon as they are well, make the necessary arrangements to return home in a timely manner. This helps to free up beds for those who need our acute care.
“We are also asking people to attend A&E for emergency care only.
“Patients attending with minor injuries may experience unavoidably long delays.
” I would like to remind the public about alternative health care options available at this time, such as urgent care and walk-in centres, community pharmacy and general practice.”
