Cardiff and Vale health chiefs warn over pressures on A&E 8 January 2014 Last updated at 11:14 Health chiefs in Cardiff are the latest in Wales to urge people not to go to A&E unless they have a real emergency. Cardiff and Vale University Health Board said the city's University Hospital of Wales was seeing high numbers of patients. Last week Hywel Dda board said Withybush Hospital in Haverfordwest was under "extreme pressure." Last month, patients in Swansea were given a similar warning about Morriston Hospital's A&E department. A Cardiff and Vale spokesman said the number of people attending the city's A&E department was currently manageable but people should contact NHS Direct if they were unsure whether they should attend.
