Description
Summary:	BACKGROUND: This investigation assesses the efficacy of a voluntary nasogastric tube feeding protocol on the weight gain of patients with anorexia nervosa, tube feeding's effect on recovery from the psychologic aspects of anorexia, patient satisfaction with treatment, and medical complications. METHODS: The study included a nonrandomized retrospective review of 381 female inpatients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of anorexia nervosa, both subtypes. A total of 155 patients received tube feeding and oral refeeding; 226 received oral refeeding alone. Recovery from the psychologic aspects of anorexia was measured by the change in Eating Disorder Inventory-2 scores between admission and discharge. Patient satisfaction with treatment was measured with a patient satisfaction questionnaire completed at discharge. Repeated measures and multivariate analyses were performed. RESULTS: When severity-of-illness and caloric intake differences between patients with and without tube feeding were controlled, patients who received tube feeding gained significantly more weight per treatment week than those who received oral kilocalories alone. Patients who received tube feeding for at least one-half their length of stay gained 1 kg/week versus 0.77 kg/week for patients receiving oral refeeding alone. Tube-fed patients evidenced no differences in recovery from anorexia's psychologic aspects, satisfaction with treatment, or medical complication frequency. CONCLUSIONS: In residential psychiatric treatment settings in which intensive therapeutic interventions and appropriate medical monitoring can manage potential psychologic and medical risks, tube feeding's weight gain benefits may be a viable and safe option in treating anorexia. Patients receiving tube feeding in addition to oral refeeding gained more weight per treatment week than those receiving oral refeeding alone. There were no differences between patient groups in recovery from the psychologic aspects of anorexia or the frequency of medical complications.
