Prediction of risks and odds of rehospitalization of patients with eating disorders in anxiety-depressive disorders

Abstract

The article represents the results of a study aimed on predicting the risks and odds of rehospitalization among patients with eating disorders in anxiety-depressive disorders. In total, 147 patients with anxiety and depressive disorders were examined. Patients were divided into a main group of 82 and a comparison group of 65 patients. The main group consisted of 21 (26%) men with a mean age of 38.33 (SD 11.53) and 61 (74%) women with a mean age of 43.15 (SD 11.44). The comparison group consisted of 19 (29%) men, mean age 37.53 (SD 9.75) and 46 (71%) women, mean age 45.22 (SD 12.17). At the time of the initial examination in the main group, 35 (43%) patients were hospitalized for the first time, 47 (57%) – rehospitalized; in the comparison group, 23 (35%) patients – for the first time hospitalized, and 42 (65%) – rehospitalized. It was found that 27 patients were rehospitalized within the next year after the intervention and treatment. Clinical-anamnestic, clinical-psychopathological and psychodiagnostic study supplemented by psychometric scales (PHQ-9 health questionnaire, Dutch Eating Behaviour Questionnaire (DEBQ), State-Trait Anxiety Inventory (STAI; C.D. Spielberger), Methodology for assessing the integrative Quality of Life Index (QLI; J.E. Mezzich)) was conducted. As a result of the study, it was found that patients in the main group had a 3.6 times lower risk of rehospitalization over the next year than patients in the comparison group. When constructing a unipolar regression model, the best predictive power and discriminative ability was demonstrated by the number of previous hospitalizations (p<0.01, AUC 0.75 (0.67-0.82)) and the intervention in the main group, which reduced the odds of rehospitalization over the next year by 4.8 times. The highest discriminative ability was demonstrated by the multiple logistic regression model (AUC 0.83 (0.76-0.88)), according to which intervention in the main group reduced the odds of rehospitalization in the next year by 5.9 times. The results of the study became the basis for the development of differentiated treatment and correctional measures for eating disorders in patients with anxiety-depressive disorders to improve the quality of care, prevent psychosocial maladjustment and improve the quality of life of this population.
