"他告訴BBC News NI："我們對這位女士的家人表示同情，顯然我們將進一步調查此事。
An elderly woman who had been waiting several hours to be admitted to the Royal Victoria Hospital died while lying on a trolley in its Emergency Department.
"Our thoughts are with the lady's family and obviously we will look into this further," he told BBC News NI.
"The emergency department on Saturday and Sunday was exceptionally busy with huge numbers of attendances - 50 to 60 patients were waiting for a bed so sometimes patients will be on trolleys.
"Of course in an ideal situation, if a patient is end-of-life we would want them to be in a room on their own with their family around them, but you have to understand the current pressure that the system is under, sometimes that the care that we provide would not be exactly what we want."
Staff who worked at the weekend said it was among the busiest, with very sick and elderly people waiting on trolleys to be admitted.
"We were already under a lot of pressure on our emergency department this weekend with the number of patients who required admission without allocated beds and we'd been helping Northern Trust throughout the weekend," he added
"And we have been doing lots of things over the past number of months to try and reduce that overcrowding, we are taking extra patients up onto wards above the number of beds that there actually are."
