Abstract
Objective: This study had two main aims: to determine the stability over time of the diagnosis borderline personality disorder (BPD) in a psychiatric hospital population; and to assess the quality and effectiveness of treatment offerred within a state mental health service.
Method: The case notes of 47 psychiatric hospital patients followed up for 3 years after the index admission were analysed.
Results: The mean number of previous psychiatric hospital admissions was 9.0, and at least 74% of the sample had further admissions (mean 3.7) during the 3 year follow-up. Comorbidity with schizophrenia and schizoaffective disorder was rare, and was only 13% with major depression. Longitudinal stability of diagnosis was very high.
Conclusions: The study firmly supported BPD as a valid diagnosis. Its treatment within the state mental health system was generally haphazard and ineffective. Post-discharge plans were implemented for only 3 subjects. Current moves toward community psychiatric treatment represent a unique opportunity for improving treatment of BPD by using existing resources more effectively.
