Aneurin Bevan Health Board says that the reason there can't be an accident and emergency department in Ysbyty Ystrad Fawr is because they can't "provide the doctors."
It says that the Caerphilly District Miners' Hospital, which has now closed, did not have the services in place that would support a full A&E service due to doctor staffing issues and so this means the Ystrad Mynach Hospital will also never operate an A&E.
It adds that the opening hours at the new hospital have been extended and there are now 8,000 extra patients being seen every a year. Other activities such as Out of Hours services with GPs and emergency medical admissions are also now supported there.
