Medical staff at the Gold Coast University Hospital say they are "shocked and saddened" to see one of their own colleagues fighting for life with serious head injuries.
Emergency department nurse Lisa Davey was found by a neighbor lying motionless in the driveway of her home on Callistemon Court in Arundel on Thursday evening.
Police have not been able to determine what caused the injuries, but said they were consistent with severe blunt force trauma.
The 37-year-old was taken to hospital where she remains on life support in the intensive care unit – the same department she until recently worked in.
A spokeswoman for the Gold Coast University Hospital said support was being offered to staff who found treating their friend and colleague confronting.
"This is obviously a very difficult time for staff, particularly those in our emergency department and intensive care unit who are coming to terms with this news," she said.
"It is always confronting for our staff when one of their colleagues and friends is hurt or unwell, and we understand this event will touch many staff members across the health service."

Ms Davey had just resigned from her job as a nurse at the hospital and was in the process of packing her belongings and moving to Cairns in Far North Queensland after the death of her mother.
Police yesterday said the cause of Ms Davey's injuries was unknown.
"Realistically, we have got no idea how these injuries occurred," Detective Inspector Brendan Smith said.
"It may be as simple as some sort of accident, but we do not know and it is best to err on the side of caution and make sure we have got everything in place just in case."
Police asked anyone with information or motorists who were driving along Olsen Avenue on Thursday afternoon and had dash-cam footage to come forward.
