Abstract
Background: We describe a transdisciplinary medical unit, referral center for the management of anorexia nervosa (AN) adult patients with extremely severe malnutrition. Method: History, organization and activity of the unit are described. Characteristics of all adult AN patients admitted for the first time in the unit between November 1997 and January 2014 and medical care provided are detailed, before discussing the value of such a unit.Results: The unit was established as an independent department in 1997 and has 180 to 200 admissions per year. The patients hospitalized in the department are clinically serious and unstable because of life-threatening somatic complications due to a low BMI (< 13 kg/m²). They are referred on criteria of somatic severity. They often had multiple hospitalizations in other acute care hospitals before being supported in the unit. Among a cohort of 386 adult AN patients admitted for the first time in the unit, mean age was 29.4 (± 11.5) years, mean BMI was 12.7 (± 2.2) kg/m² and 78.2% of patients had already been hospitalized in other hospitals. Intensive medical care, both somatic and psychiatric, are provided thanks to a transdisciplinary therapeutic program, where objectives are to optimize care and enable a therapeutic alliance between patient and caregiver, The goals of treatment are to medically stabilize the patient, to initiate progressive refeeding and to start supportive psychotherapy before being transferred to a psychiatric eating disorder unit.Conclusion: This specialized transdisciplinary unit where physician nutritionists and psychiatrists coordinate medical care together, allow a better understanding and management of extreme malnutrition associated with AN. Thanks to their expertise, care teams are less critical and less rejecting towards patients. Thus, therapeutic alliance could be optimized.
