Outcomes of low‐weight patients with avoidant/restrictive food intake disorder and anorexia nervosa at long‐term follow‐up after treatment in a partial hospitalization program for eating disorders

摘要

Abstract Objective To assess long‐term outcomes of patients with avoidant/restrictive food intake disorder (ARFID) treated in a partial hospitalization program (PHP) for eating disorders (ED). Method A cross‐sectional study comparing patients with ARFID to those with anorexia nervosa (AN) who had been discharged from a PHP for at least 12 months was performed. Percent median body mass index (%MBMI), scores on the Children's Eating Attitudes Test (ChEAT), and treatment utilization were assessed, with intake and discharge data collected via retrospective chart review. Results Of the 137 eligible patients, 62 (45.3%) consented to follow‐up data collection. Patients with ARFID and AN exhibited similar increases in %MBMI from intake to discharge and reported low scores on the ChEAT by discharge. Patients with ARFID and AN maintained good weight outcomes and low ChEAT scores at follow‐up. Most participants were still receiving outpatient treatment from a variety of providers, although fewer with ARFID than AN continued to receive services from our multidisciplinary ED clinic. Discussion Patients with ARFID and AN exhibit similar improvements in %MBMI when treated in the same PHP and appear to maintain treatment gains at long‐term follow‐up. Additionally, most patients continue to utilize outpatient services after being discharged from a PHP.
