I think there are 2 programs at Columbia and that is where the confusion arises. There is the residential unit at the hospital, which is a research based program which has been around for awhile, and there is also a newer program which is outpatient FBT for teens and has family support.
H2O, Boston was a little difficult to navigate as far as treatment providers go, even though they have some of the best hospitals in the country.
Boston Children's has an ED program which is outpatient and does FBT with teens and their families. They have some good MD's who specialize in eating disorders, and nutritionists and therapists and they all work together so they all know how the patient is progressing. They do have a unit for medical stabilization if that is needed.
Mass General also has an FBT program, which works with teens and their families on an outpatient basis.
I don't know if there is an advantage to working with one of the hospital programs if your daughter is having trouble getting off the NG tube or could need supplemental NG feeding as she moves forward, but you could look into that if you wanted to.
