The inquest heard Emily made improvements when she was moved from West Lane to Ferndene in Prudhoe, run by Cumbria, Northumberland, Tyne and Wear NHS Foundation Trust (CNTW).
In her seven months there she was building “good relationships” with nurses and “got on well”, David said.
“Most importantly she had structure to her day.
“She was enjoying it.”
But when she turned 18 in February 2020 she had to be moved to an adult ward, and due to where she lived that meant a return to TEWV’s care.
“We didn’t want that, she didn’t want that, even the nurses at Ferndene didn’t want that because she was doing well,” David said.
“But it had to happen, it did happen, it was just downhill from there.”
He said experts had since said the transition from child to adult hospitals should be done more gradually with a bigger grace period, rather than an immediate move upon turning 18.
