Abstract

Objective: Anorexia nervosa (AN) is associated with one of the highest mortality rates of any psychiatric disorder but limited mortality data were reported for those with extremely severe malnutrition. This study aimed to estimate standardized mortality ratio (SMR), investigate predictive factors of mortality and causes of death among a sample of patients with AN admitted to a specialized clinical nutrition unit (CNU) because of extremely severe malnutrition. Methods: Between 11/27/1997 and 01/15/2014, vital status was determined for 384 patients admitted for AN at the first time in the CNU. Sociodemographic, anamnestic, and clinical data were collected. We calculated the SMR. Univariate and multivariate Cox regression analyses were performed to identify mortality predictors. Results: Crude mortality rate was 11.5%. (44 deaths) and SMR 15.9 [CI 95% (11.6–21.4)], 5.2 years post inpatient treatment. Mortality predictors at the time of hospitalization were as follows: older age, occurrence of an in‐hospital suicide attempt, transfer to medical intensive care unit and the following somatic complications: frank anemia, dysnatremia, infectious and cardiac complications. Other predictors of mortality were: past or present history of discharge against medical advice, hematological comorbidities (not related to AN). A longer inpatient length of stay was a protective factor. Conclusion: Very severely malnourished patients with AN hospitalized in a medical unit because of extremely severe somatic issues have a medium‐term mortality rate higher than the general population and even higher than patients in tertiary specialized ED units. This study highlights predictive factors of mortality that will help clinicians in recognizing and managing patients at risk of death.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
