Evaluation of a Nutrition Rehabilitation Protocol in Hospitalized Adolescents With Restrictive Eating Disorders

PurposeNutritional rehabilitation is an essential part of inpatient treatment for adolescents with restrictive eating disorders (ED). The purpose of this study was to examine weight gain, prevalence of refeeding syndrome, and nutritional composition of the diet in hospitalized adolescents with anorexia nervosa (AN) and eating disorder not otherwise specified (EDNOS), restrictive type, on a structured nutrition rehabilitation protocol (NRP).MethodsAn evidence-based NRP was implemented on the inpatient eating disorders unit at the Hospital for Sick Children in June 2011. Adolescents 12–18 years of age with AN or EDNOS, an ideal body weight (IBW) of 70% or greater, no clinical or metabolic signs of refeeding syndrome, and on their first admission were assigned to the NRP. A retrospective chart review between June 2011 and June 2012 was completed. A repeated measures analysis was used to determine the mean rate of weight gain. Mean cumulative % change in body mass index (BMI) was plotted against days to assess daily weight trajectory.ResultsTwenty-nine patients, mean age of 14.7 (SD ± 1.5) years, were included in the study. A total of 3.5% developed hypophosphatemia on day 1. Mean weight gain was .24 kg/day (p < .0001) and 1.7 kg/week. An increase in mean cumulative % change in BMI was observed from days 2–14. Actual caloric intake was 98%–113% of the prescribed intake. Macronutrient distribution was within acceptable limits based on dietary reference intakes.ConclusionsThe NRP is considered effective, efficient, and safe. Further research is needed to explore the effectiveness and safety of NRPs in other populations.
