Complexity of illness and adjunctive benzodiazepine use in outpatients with bipolar I or II disorder: results from the Bipolar CHOICE study.

ABSTRACT: Benzodiazepines are widely prescribed for patients with bipolar disorders in clinical practice, but very little is known about the subtypes of patients with bipolar disorder or aspects of bipolar illness that contribute most to benzodiazepine use. We examined the prevalence of and factors associated with benzodiazepine use among 482 patients with bipolar I or II disorder enrolled in the Bipolar CHOICE study. Eighty-one subjects were prescribed benzodiazepines at study entry and were considered benzodiazepine users. Stepwise logistic regression was used to model baseline benzodiazepine use versus nonuse, using entry and exit criteria of P < 0.1. In bivariate analyses, benzodiazepine users were prescribed a significantly higher number of other psychotropic medications and were more likely to be prescribed lamotrigine or antidepressants as compared with benzodiazepine nonusers. Benzodiazepine users were more likely to have a diagnosis of bipolar I disorder and comorbid anxiety disorder, but not comorbid alcohol or substance use disorders. Benzodiazepine users also had experienced more anxiety and depressive symptoms and suicidality, but not irritability or manic symptoms, than did benzodiazepine nonusers. In the multivariate model, anxiety symptom level (regardless of diagnosis), lamotrigine use, number of concomitant psychotropic medications, college education, and high household income predicted benzodiazepine use. Benzodiazepine use in patients with bipolar disorders is associated with greater illness complexity as indicated by a higher number of concomitant psychotropic medications and higher anxiety symptom burden, regardless of a comorbid anxiety disorder diagnosis. Demographic factors were also important determinants of benzodiazepine use, which may be related to access to care and insurance coverage for benzodiazepines.

Project description:ImportanceSeveral psychotherapy protocols have been evaluated as adjuncts to pharmacotherapy for patients with bipolar disorder, but little is known about their comparative effectiveness.ObjectiveTo use systematic review and network meta-analysis to compare the association of using manualized psychotherapies and therapy components with reducing recurrences and stabilizing symptoms in patients with bipolar disorder.Data sourcesMajor bibliographic databases (MEDLINE, PsychInfo, and Cochrane Library of Systematic Reviews) and trial registries were searched from inception to June 1, 2019, for randomized clinical trials of psychotherapy for bipolar disorder.Study selectionOf 3255 abstracts, 39 randomized clinical trials were identified that compared pharmacotherapy plus manualized psychotherapy (cognitive behavioral therapy, family or conjoint therapy, interpersonal therapy, or psychoeducational therapy) with pharmacotherapy plus a control intervention (eg, supportive therapy or treatment as usual) for patients with bipolar disorder.Data extraction and synthesisBinary outcomes (recurrence and study retention) were compared across treatments using odds ratios (ORs). For depression or mania severity scores, data were pooled and compared across treatments using standardized mean differences (SMDs) (Hedges-adjusted g using weighted pooled SDs). In component network meta-analyses, the incremental effectiveness of 13 specific therapy components was examined.Main outcomes and measuresThe primary outcome was illness recurrence. Secondary outcomes were depressive and manic symptoms at 12 months and acceptability of treatment (study retention).ResultsA total of 39 randomized clinical trials with 3863 participants (2247 of 3693 [60.8%] with data on sex were female; mean [SD] age, 36.5 [8.2] years) were identified. Across 20 two-group trials that provided usable information, manualized treatments were associated with lower recurrence rates than control treatments (OR, 0.56; 95% CI, 0.43-0.74). Psychoeducation with guided practice of illness management skills in a family or group format was associated with reducing recurrences vs the same strategies in an individual format (OR, 0.12; 95% CI, 0.02-0.94). Cognitive behavioral therapy (SMD, -0.32; 95% CI, -0.64 to -0.01) and, with less certainty, family or conjoint therapy (SMD, -0.46; 95% CI, -1.01 to 0.08) and interpersonal therapy (SMD, -0.46; 95% CI, -1.07 to 0.15) were associated with stabilizing depressive symptoms compared with treatment as usual. Higher study retention was associated with family or conjoint therapy (OR, 0.46; 95% CI, 0.26-0.82) and brief psychoeducation (OR, 0.44; 95% CI, 0.23-0.85) compared with standard psychoeducation.Conclusions and relevanceThis study suggests that outpatients with bipolar disorder may benefit from skills-based psychosocial interventions combined with pharmacotherapy. Conclusions are tempered by heterogeneity in populations, treatment duration, and follow-up.

Project description:BackgroundBipolar disorder is a mental illness in which manic and depressive states are repeated, causing psychosocial dysfunction. Manic/hypomanic episodes cause problems with interpersonal, social and financial activities, but there is limited evidence regarding the predictors of manic/hypomanic episodes in real-world clinical practice.MethodsThe multicenter treatment survey on bipolar disorder (MUSUBI) in Japanese psychiatric clinics was administered in an observational study that was conducted to accumulate evidence regarding bipolar disorder in real-world clinical practice. Psychiatrists were asked to complete a questionnaire about patients with bipolar disorder who visited 176 member clinics of the Japanese Association of Neuro-Psychiatric Clinics by conducting a retrospective medical record survey. Our study extracted baseline patient characteristics from September to October 2016, including comorbidities, mental status, duration of treatment, Global Assessment of Functioning (GAF) score, and pharmacological treatment details. We investigated the presence or absence of manic/hypomanic episodes over the course of one year from baseline to September-October 2017.ResultsIn total, 2231 participants were included in our study, 29.1% of whom had manic/hypomanic episodes over the course of one year from baseline. Binomial logistic regression analysis revealed that the presence of manic/hypomanic episodes was correlated with lower baseline GAF scores, rapid cycling, personality disorder, bipolar I disorder, and a mood state with manic or mixed features. Substance abuse was also a risk factor for manic episodes. There was no significant association between a baseline antidepressant prescription and manic/hypomanic episodes.ConclusionsIn Japan, 29.1% of outpatients with bipolar disorder had manic/hypomanic episodes over the course of one year. Our study suggested that a low GAF score, rapid cycling, personality disorder, bipolar I disorder, substance abuse, and baseline mood state could be predictors of manic/hypomanic episodes. Based on our findings, an antidepressant prescription is not a predictor of manic/hypomanic episodes.
