Bipolar Disorder and Treatment

Polypharmacy and overprescription of off-label medications are common in patients with borderline personality disorder (BPD). The aim of the present naturalistic study was to explore whether the skills training module of dialectical-behavioural therapy (DBT) can reduce polypharmacy in these patients in routine clinical practice.Retrospective, observational study of 377 patients with a primary diagnosis of BPD consecutively admitted to the BPD outpatient unit from 2010 through 2020. All patients were invited to participate in the DBT skills training module (DBT-ST). DBT-ST participants (n = 182) were compared with a control group who did not participate in DBT-ST (n = 195). Pre-post intervention changes in medication load and use of antidepressants, benzodiazepines, mood stabilizers, and antipsychotics were evaluated.At baseline, most patients (84.4%) were taking at least one medication and 46.9% were on polypharmacy. Compared to controls, patients in the DBT-ST group presented a significant reduction in the number of medications (2.67-1.95 vs. 2.16-2.19; p < 0.001), medication load (4.25-3.05 vs. 3.45-3.48; p < 0.001), use of benzodiazepines (54.4%-27.5% vs. 40%-40.5%; p < 0.001), mood stabilizers (43.4%-33% vs. 36.4%-39.5%; p < 0.001), and antipsychotics (36.3%-29.1% vs. 34.4%-36.9%; p < 0.001).These findings suggest that patients with BPD can benefit from the DBT-ST module, which may reduce the medication load, particularly of sedatives. The results suggest that DBT-ST may be useful to treat overmedication in patients with BPD and could help to promote "deprescription" in clinical practice.
