The new multi-million unit has been delayed for more than a year.
However General Manager of the hospital, Sean Murphy, has told staff they will now officially begin moving into the unit in mid-September.
The hospital is now in the process of equipping the new unit and this is being overseen by Dr Anne Flood, Director of Nursing/Midwifery at LGH.
“The current plan is to move into the new Emergency Department and Medical Assessment Unit in mid-September with the medical wards to relocate in the following two weeks.
“This timetable will provide the necessary time to equip the facility and agree and implement new staffing arrangements within the departments and wards that are moving.
“It will also allow for the co-ordination of clinical and non-clinical support functions,” said the letter.
The memo adds that more details on the opening of the unit will follow in the coming weeks.
“This is both an exciting and challenging time for the hospital and I welcome the efforts of all involved in ensuring that we make this move to the new facility which will allow us to care for patients in a 21st century environment,” said Mr Murphy.
