Medication Utilization Patterns and Methods of Suicidality in Borderline Personality Disorder

Abstract

Background: Borderline personality disorder (BPD) is a psychiatric disorder characterized by suicidal thoughts/attempts and instability of mood, interpersonal relationships, and self-image. Patients with BPD engage in manipulative acts in apparent attempts to exert control in their interpersonal relationships. This issue of control may also be exhibited in their manner of self-medication. Objective: To examine the medication utilization patterns of patients with BPD versus patients without personality disorders in a control group and to compare methods of suicidality between the groups. Methods: A randomized, retrospective, chart review study was conducted at an academic medical center psychiatric hospital. The study examined the medication utilization patterns and methods of suicidality displayed over a one-year period for 29 patients hospitalized with BPD versus 29 patients in a control group. Results: The number of psychotropic, non-psychotropic, and total drugs on admission and discharge was significantly greater for patients with BPD compared with patients in the control group. There was no significant difference between the 2 groups with respect to overdose and cutting methods of suicidality. The mean number of Axis III discharge diagnoses in the control group upon discharge was significantly less than that in the study group. Approximately 25% of patients with BPD considered overdosage as a means to end their life. Conclusions: As patients with BPD receive more medications than patients without the disorder and often exhibit suicidal thoughts/attempts, clinicians should closely monitor the use of all medications.
