In most cited stories Tufts has never agreed with Children's on a diagnosis.
And I can't imagine why Justina would have to be in a locked psych ward just because her parents couldn't accept a psych diagnosis. That makes no sense. Even the diagnosis Justina has received at Children’s is usually treated on an out patient basis. Why can't friends or any other relatives visit her? What about Foster care if you think it's the parents? Justina was skating, got the flu with visible vomiting and then all of a sudden needed 24 hour a day in patient mental health treatment? As a child nothing can damage mental health much more then spending the last 13 months basically isolated from all the friends and family you've ever known! 1hr/wk supervised is not adequate.
Probably the only psych ward for peds at BCH is a locked psych ward. I am not sure about why they did not place her with other family members, unless maybe the parents refused to give out the names? Or CPS thought the parents would visit unsupervised? From what I have read, the medical providers thought Justina got worse when mom was in the room. They probably thought any interaction with the parents would be detrimental. Placing in a foster situation in which the parents knew the address would not be good.
I am just speculating here. However, I dont think there was evil intent at BCH. They cannot defend themselves.You get to that opinion after seeing huge numbers of child abuse cases. It changes your perspective on the issue.
