There are very few follow-up studies (or heck, any studies at all) of anorexia treatment, so I was glad to see this one, done in Norway a couple of years ago. I wasn't so glad of its outcomes.
The study was a one-year followup of adult anorexics who'd been treated on an inpatient unit. Of the 24 patients they followed up with, 10 (42%) had improved one year later, while 14 (58%) had "poor outcomes."
I'm grateful that they did the study, frankly, because most of the numbers on inpatient anorexia treatment come straight from the clinics and units, which often stand to make a tidy sum on treatment. Their followups are usually done at discharge, so they don't take into account what almost always happens after that: relapse and rehospitalization.
So bravo to the researchers in Vikersund. And chalk up another reason why family-based (Maudsley) treatment is an excellent option for anorexia.
