Patient selection: anorexia nervosa, >= 12 years of age
Outcome: in-hospital mortality
Risk factors for mortality from multivariate logistic regression:
(1) male sex (OR 2.2)
(2) older age at first hospital admission (OR 1.1)
(3) lower ratio for body weight to ideal body weight (thinness index, OR 0.9)
(4) hypotension requiring a vasopressor/catecholamine (OR 8.7)
(5) Charlson comorbidity index (OR 1.2)
Treatment in a university hospital was associated with a lower risk of mortality (OR 0.45).
The mortality for a patient admitted for the first time as an adolescent was low and rose with age, especially after 50. A first admission at an age >= 80 was associated with a 16% mortality rate.
The refeeding syndrome needs to be considered when resuscitating the patient.
