Background There is a scarcity of national United States (U.S) data on emergency department (ED) utilization by patients with eating disorders. This study aims to determine the most common reasons for ED visits of patients with eating disorders, as well as baseline characteristics of patients who present due to eating disorders. Methods We obtained data from the Nationwide Emergency Department Sample (NEDS), the largest all-payer ED database in the United States. Each ED visit in NEDS 2018 can have only one "principal" diagnosis, which is the main reason for the visit and up to 34 "secondary" diagnoses. We abstracted data for all ED visits with "any" diagnosis of an eating disorder, using the ICD-10 code "F50". We highlighted the 10 most common "principal" diagnoses based on the organ system involved and the 10 most specific "principal" diagnoses for all ED visits by patients with any diagnosis of eating disorder. We then highlighted baseline characteristics of ED visits with a "principal" diagnosis of an eating disorder. Results There were a total of 56,901 ED visits for patients with eating disorders in 2018. Among these, 7,979 had an eating disorder as the "principal" diagnosis. Patients who visited the ED principally for eating disorders were more likely to be young females and came from higher-income households; about a third were admitted with 22.1 million U.S. dollars in aggregate ED charges. Mental disorders, and injuries and poisoning were the most common principal diagnosis by organ system categories, while eating disorders, major depression disorder (MDD), hypokalemia, and dehydration are common specific reasons for ED visits among patients with eating disorders. Conclusions Eating disorders, and its medical complications and psychiatric comorbidities such as MDD are common reasons for ED visits among patients with eating disorders. Management of the underlying eating disorder and their psychiatric comorbidities through a multidisciplinary approach in the outpatient setting is invaluable in reducing ED utilization by these patients. |
