18 nursing posts lying vacant across Belfast A&Es
There are 18 empty nursing posts across the three accident and emergency departments in the Belfast Health & Social Care Trust.
Health bosses said they are taking steps to recruit staff to work in 12 of the 18 vacancies but it could be several months before the posts are filled.
Concerns were raised over rota gaps at A&Es at the Royal Victoria, Mater and Royal Belfast Hospital for Sick Children (RBHSC).
Figures released by the trust show more than 200 patients waited longer than 12 hours in casualty departments last month.
One child waited longer than 12 hours in the A&E at RBHSC, while 170 and 42 patients waited longer than 12 hours in the RVH and Mater Hospital A&Es respectively.
The issue has come to light after the A&E at Belfast City Hospital was closed.
A Belfast Trust spokeswoman said it has used nurses from agencies in order to fill as many of the rota gaps as possible.
