Objectives: Nearly one-quarter of individuals diagnosed with avoidant/restrictive food intake disorder (ARFID) require medical admission. There have been efforts to characterize ARFID in outpatient and intensive day treatment settings; however, authors of few studies have examined this presentation in the inpatient pediatric hospital setting. In this study, we aim to further characterize patients presenting to the hospital with concerns for ARFID.
Methods: This study involved a retrospective chart review of medically admitted patients with ARFID seen by the psychiatry consultation service at a tertiary care New England pediatric hospital from 2015 to 2016.
Results: The typical hospitalized patient with ARFID was a 12.9-year-old, white girl with previous history of outpatient mental health treatment, anxiety disorder, and gastrointestinal-related diagnoses admitted to adolescent medicine or pediatric hospitalist services with >1 year of feeding difficulties often triggered by a precipitating event. Despite >80% of subjects receiving evaluations as outpatients for feeding-related concerns, including 60.5% seeing their primary care provider, <20% were diagnosed with ARFID before hospitalization. The average length of admission was 8 days. All imaging, scopes, and swallow studies conducted during the admission were nonrevealing. Almost half of patients required enteral tube feeds, and 63.2% required psychiatric medications during the admission. Only 31.6% of patients had the ARFID diagnosis documented in their discharge notes.
Conclusions: Consistent identification of ARFID remains variable, underrecognized by community providers, and underdocumented by hospital providers. Accurate recognition of ARFID and additional study into contributory factors and treatment approaches may help improve effective health care use and treatment outcomes.
