Factors supporting hospitalization in adolescents and young adults with an eating disorder

One or more of the following justify hospitalization:
1.	≤75% median BMI for age and sex
2.	Dehydration
3.	Electrolyte disturbance (hypokalemia, hyponatremia, hypophosphatemia)
4.	EKG abnormalities (e.g., prolonged QTc or severe bradycardia)
5.	Physiological instability  • Severe bradycardia (heart rate <50 beats/minute daytime; <45 beats/minute at night)  • Hypotension (<90/45 mm Hg)  • Hypothermia (body temperature <96°F, 35.6°C)  • Orthostatic changes in pulse (sustained increase in HR >30 bpm in adults aged >19 years or >40 bpm in adolescents aged <19 years or sustained decrease of blood pressure (>20 mm Hg systolic or >10 mm Hg diastolic) [28,29]
6.	Arrested growth and development
7.	Failure of outpatient treatment
8.	Acute food refusal
9.	Uncontrollable bingeing and purging
10.	Acute medical complications of malnutrition (e.g., syncope, seizures, cardiac failure, pancreatitis, etc.)
11.	Comorbid psychiatric or medical condition that prohibits or limits appropriate outpatient treatment (e.g., severe depression, suicidal ideation, obsessive-compulsive disorder, type 1 diabetes mellitus)

EKG = electrocardiogram; HR = heart rate; QTc = corrected QT.
