Day hospital treatment of eating disorders is growing in importance and has financial and clinical advantages in comparison to inpatient settings. It is cheaper and day-hospital treatment allows patients to maintain their social contacts and to apply the lessons learnt in the course of their treatment in their everyday lives. A study of 83 eating-disorder patients in Germany (47 with anorexia and 36 with bulimia) assessed them before treatment in a day hospital, at the end of their treatment and 18 months after treatment. Outcome measures were body-mass index, disturbed eating attitudes and behaviours, frequencies of binging and purging and general mental health. At the end of the day-hospital treatment significant improvement could be found on all outcome variables and the effects were maintained or improved until follow-up. At follow-up 40.2% of anorexia patients and 40.4% of bulimia patients could be classified as remitted and the patients' general mental health was also significantly improved.
