Socio-demographic predictors of the time interval between successive hospitalizations among patients with borderline personality disorder

Abstract

Background: Borderline personality disorder (BPD) affects 0.7 to 2.7% of the adult population and higher rates are reported in inpatient care. Hospitalizations of BPD patients are a complex and controversial challenge for mental health professionals. Recurrent hospitalizations are common and it is essential to identify risk factors that characterize patients who benefit from their hospitalization and those who return to the ward shortly after discharge. Aim: To investigate the potential link between BPD patients’ socio-demographic factors and the expected time interval between their successive hospitalizations. Methods: A retrospective analysis of 1051 hospitalization records from 174 BPD patients. Through univariate, bivariate, and multivariate analyses, we investigated the possible relationship between patients’ primary socio-demographic factors and the time between their successive hospitalizations. Results: Patients’ age, marital status, and living arrangement were found to be statistically connected with the time interval between successive hospitalizations. Specifically, being older, married and/or patients to live with one’s spouse/partner seem to be linked with a longer time interval between successive hospitalizations compared to patients who are young, single/divorced and/or those who live with their parents. Conclusions: The expected time interval between successive hospitalization of BPD patients can be partly explained by their socio-demographic characteristics.
