Low Hospital Inpatient Readmission Rate in Patients with Borderline Personality Disorder: A Naturalistic Study at Southern Health, Victoria, Australia

Abstract

To study how the standard management protocol and the special management contract relate to the clinical profile of patients with borderline personality disorder and their hospital admission pattern. A retrospective review was undertaken using naturalistic data from the Client Management Interface over a 2-year period. The standard management protocol patient group and the special treatment contract patient group were compared with respect to variables which included basic demographic data, number of admissions, length of stay and comorbidity. Eighty patients received a diagnosis of borderline personality disorder. The majority (81.2%) were managed with the standard management protocol and only 41.5% had more than one admission. For those who received a special treatment contract (18.8%), 93.3% of them had more than one admission. The special treatment contract group had a significantly higher total number of admissions (p < 0.001), a higher number of admissions when they received (p < 0.001) and did not receive (p = 0.001) a diagnosis of borderline personality disorder, a higher number of comorbidities (p = 0.004) but not more presentations to the emergency department. Most patients with borderline personality disorder treated with the standard management protocol had a low readmission rate. The small group of patients with comorbidities managed with a special treatment contract had multiple readmissions but not more crisis presentations to the emergency department. Further studies are required to elucidate the therapeutic mechanism of the standard management protocol and special treatment contract and how that impacts on presentations and admissions to a hospital.
