Recurrent Mental Health Presentations to Public Hospital Services: A Focus on Borderline Personality Disorder.

Objective: To investigate associations between patients with borderline personality disorder (BPD)-related symptoms and their hospital presentations as well as the effect of inpatient length of stay (LOS) on time to hospital re-presentation.
Methods: A retrospective cohort design was used to investigate mental health emergency department (ED) visits and inpatient admissions. The cohort comprised 13,320 men and 12,290 women with a follow-up period between January 1, 2014, and December 31, 2019.
Results: Across all presentations in the study period, approximately 4% of mental health patients were discharged from ED or inpatient admission with primary diagnosis of BPD. Both male and female patients with BPD were at higher risk of hospital re-presentation when compared to patients with any other type of mental disorder ( P  < .01). Patients with BPD who had LOS > 14 days in their first inpatient admission were, on average, more likely to experience a repeat ED or inpatient presentation 58 days sooner than patients who had LOS < 2 days ( P  = .036).
Conclusions: Findings suggest the need for ( a ) more accurate recording of BPD and related presentations, ( b ) more in-depth investigations of BPD care pathways, and ( c ) identifications of subpopulations who may benefit from a specific inpatient length of stay.
