BACKGROUND:Learning Health Networks (LHNs), such as the one described in Savitz et al. (in press), involve employing a network of treatment centers to produce standardized data from routine clinical practice, produce knowledge from that data, and systematically use that knowledge to inform care. To date, there are limited examples of LHNs in psychiatry. It is essential to establish robust dialogue around best practices for building LHNs to advance precision medicine in psychiatry. METHODS:A task group consensus on key elements of LHNs as applied to mood disorders was convened. Task group members reviewed current literature and ongoing LHN network efforts and evaluated opportunities and gaps within psychiatry broadly, and mood disorders specifically. RESULTS:Task group members noted four key considerations for building LHNs for mood disorders. First, obtain qualitative and quantitative stakeholder input at every stage of development, specifically input from patients and patients' families, clinicians and health system leadership. Second, collect data on objective measures of functioning, such as neuropsychological testing, quality of life indicators, and blood-based markers of health, alongside more standard measures such as symptom severity. Third, carefully consider the details of how new evidence-based practices will be identified and implemented. Fourth, identify a plan for sustainability. LIMITATIONS:Literature was reviewed and discussed among expert task group members, but this was not a systematic review. CONCLUSIONS:With stakeholder input, data on functioning as well as symptom severity, thoughtful implementation strategies, and an eye to sustainability, LHNs represent an important opportunity for advancement in the treatment of mood disorders.
Background The subgenual cingulate cortex (SGC) has been identified as a key structure within multiple neural circuits whose dysfunction is implicated in the neurobiology of depression. Deep brain stimulation in the SGC is thought to reduce and normalize local metabolism, causing normalization of circuit behavior and an improvement in depressive symptoms. We hypothesized that nonablative stereotactic radiosurgery (SRS) to the SGC would reduce local metabolism and reduce the severity of depression in patients with treatment-resistant bipolar depression. Methods Under the FDA's Humanitarian Device Exemption program, patients were screened for inclusion and exclusion criteria. Three volunteers meeting the criteria provided informed consent. Bilateral SGC targets were irradiated to a maximum dose of 75 Gy in one fraction. Subjects were followed for one year following the procedure with mood assessments (Hamilton Depression Rating Scale (HDRS), Clinical Global Impression-Improvement, Clinical Global Impression-Severity, and Young Mania Rating Scale), neurocognitive testing (Delis-Kaplan Executive Function System, Wechsler Adult Intelligence Scale III digit span, and California Verbal Learning Test II), and imaging. Further imaging was completed approximately two years after the procedure. Clinical improvement was defined as a ≥50% reduction in HDRS. Results Two of the three subjects showed clinical improvement in depressive symptoms during the follow-up period, while one subject showed no change in symptom severity. One of three subjects was hospitalized for the emergence of an episode of psychotic mania after discontinuing antipsychotic medications against medical advice but promptly recovered with the reinstitution of an antipsychotic. Sequential assessments did not reveal impairment in any cognitive domain assessed. For one of the three subjects, MRI imaging showed evidence of edema at 12 months post-SRS, which resolved at 22 months post-procedure. In a second of three patients, there was evidence of local edema at the target site at long-term follow-up. All imaging changes were asymptomatic. Conclusion Radiosurgical targeting of the SGC may be a noninvasive strategy for the reduction of severe depression in treatment-resistant bipolar disorder. Two out of three patients showed clinical improvement. While these results are promising, further study, including improvements in target selection and dosing considerations, is needed.
Background Sleep pattern alteration is a core feature of bipolar disorder (BD), often challenging to treat and affecting clinical outcomes. Suvorexant, a hypnotic agent that decreases wakefulness, has shown promising results in treating primary insomnia. To date, data on its use in BD are lacking. This study evaluated the efficacy and tolerability of adjunctive suvorexant for treatment-resistant insomnia in BD patients.Methods Thirty-six BD outpatients (19 BDI, 69.4% female, 48.9 [+/- 15.2] years) were randomized for 1 week to double-blind suvorexant (10-20 mg/day) versus placebo. Then, all subjects who completed the randomized phase were offered open suvorexant for 3 months. Subjective total sleep time (sTST) and objective total sleep time (oTST) were assessed.Results During the randomized control trial (RCT) phase, an overall increase in the oTST emerged, which was statistically significant for the Cole-Kripke algorithm (p = 0.035). The comparison between the suvorexant and placebo groups was limited by significant differences between measurements at baseline. During the open phase, no significant improvement was detected relative to either sTST and oTST. No adverse events nor major intolerances were reported.Discussion Efficacy results are inconsistent. During the RCT phase, only a small increase in the objective oTST emerged, while during the open phase, no significant improvement was detected. While this is the first ever study of suvorexant in BD-related insomnia, the limitation of the small sample and the high rate of dropouts limits the generalizability of these findings. Larger studies are needed to assess suvorexant in treating BD-related insomnia.
Objectives: To assess feasibility and clinical significance of tracking mania and depression in community college students before and after early identification and intervention. Methods: From Affective Illness to Recovery: STudent Access to Rapid Treatment (FAIRSTART) is an early intervention program to provide diagnostic therapeutic consultation, short-term care, and community ongoing care referral for 18-28 year-old outpatient community college students (mean age 22.9 +/- 4.0 years) experiencing manic symptoms. Over three years, 54 FAIRSTART participants (70% with DSM-IV bipolar I/II/not otherwise specified disorder, BDI/II/NOS) were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation (ADE) and followed (range: one-time consult to 4.3 +/- 3.6 visits over 3-6 month follow-up) with the STEP-BD Clinical Monitoring Form. Results: 38/54 patients (70%) had BDI/II/NOS, 11 unipolar depression (20%), 1 psychosis spectrum disorder (2%), 2 dysthymia/persistent depressive disorder (4%), and 2 incomplete intake with mood disorder diagnosis undetermined (4%). Average illness duration was 9.1 +/- 5.3 years. Among the 38 BD I/II/NOS patients, depression (SUM-D, t(30)=6.5; p<0.001) and mania (SUM-M, t(30)=4.7; p<0.001) scores improved significantly from baseline to last visit, with 17 (44.7%) reporting recovery by time transitioned from FAIRSTART to community care (after 4.3 +/- 3.6 visits). Conclusions: Short-term, early intervention in community college students with mood symptoms appeared feasible and yielded significant improvements in depression and mania scores. However, additional studies, with longer-term follow-ups, larger sample sizes, and comparison to current care standards, are needed to determine this early intervention program's impact on trajectory of mania symptoms in transitional age young adult populations.
Assess bipolar disorder subtype and treatment location effects on bipolar disorder core pharmacotherapy. Outpatients not in a syndromal episode referred to the University of Milan and Stanford University Bipolar Disorder Clinics were assessed with SCID for the fourth Edition of the Diagnostic and Statistical Manual of Mood Disorders, and the Systematic Treatment Enhancement Program for Bipolar Disorder Affective Disorders Evaluation, respectively. Prevalence and clinical correlates of antidepressant, antipsychotic, and mood stabilizer use, in aggregate and individually, were compared in bipolar I (BDI) versus II (BDII) patients in Milan/Stanford and in Milan versus Stanford patients, stratified by subtype. Milan/Stanford pooled BDI versus BDII patients significantly more often took antipsychotic (69.8 versus 44.8%), mood stabilizers (68.6 versus 57.7%), and valproate (40.1 versus 17.5%), and less often took antidepressants (23.1 versus 55.6%) and lamotrigine (9.9 versus 25.2%). Milan versus Stanford patients (stratified by bipolar disorder subtype) significantly more often took antipsychotic (BDI and BDII), antidepressants (BDII), and valproate (BDII), and less often took lamotrigine (BDI). Research regarding bipolar disorder core pharmacotherapy relationships with bipolar subtype and treatment location is warranted to enhance clinical management.
Aims: Antidepressant use is controversial in bipolar disorder (BD) due to questionable efficacy/psychiatric tolerability. We assessed demographic/clinical characteristics of baseline antidepressant use in BD patients. Methods: Prevalence and correlates of baseline antidepressant use in 503 BD I and BD II outpatients referred to the Stanford Bipolar Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. Results: Antidepressant use was 39.0%, overall, and was higher in BD II versus BD I (46.9% versus 30.5%, p = 0.0002). Both BD I and BD II antidepressant compared to non-antidepressant users had higher rates of complex pharmacotherapy (>= 4 mood stabilizers, antipsychotics, and/or antidepressants) and use of other psychotropics. Antidepressant use in BD II versus BD I was higher during euthymia (44.0% vs. 28.0%) and subsyndromal symptoms (56.1% vs. 28.6%), but not depression or mood elevation. Limitations: American tertiary BD clinic referral sample receiving open naturalistic treatment. Conclusions: In our sample, antidepressant use was higher in BD II versus BD I patients, and was associated with markers of heightened illness severity in both BD I and BD II patients. Additional research is warranted to investigate these complex relationships.
Objectives: To determine whether the risk of suicidal ideation or behavior during mixed states exceeds that attributable to the depressive components of these states alone in bipolar disorder. Methods: We utilized real-world, longitudinal clinical data collected on 290 patients with bipolar disorders (bipolar I, bipolar II, and bipolar not otherwise specified (NOS)) from the National Network of Depression Centers (NNDC) Clinical Care Registry (CCR) seen for 891 visits over a mean of 27.5 weeks. Depressive symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9), manic symptoms with the Altman Self-Rating Mania (ASRM), and suicidal ideation and behavior with the Columbia-Suicide Severity Rating Scale (C-SSRS), obtained as part of the routine, measurement-based care provided across the NNDC. The relations between depressive symptoms, manic symptoms, and the interaction thereof (mixed symptoms) on coinciding suicidal ideation and behavior were modeled in generalized linear mixed models. Results: Depressive symptoms, as measured by the PHQ-9, were strongly associated with suicidal ideation and behavior (p < 0.0001), while there was no significant association with manic symptoms as measured by the ASRM or the interaction between depressive and manic symptoms. Similar results were observed when the outcome was restricted to suicidal behavior and when mood was modeled categorically. There was evidence of a gender by ASRM interaction (p = 0.011) and risk of suicidal ideation or behavior was significant for women, but not men with manic symptoms. Limitations: Diagnoses were based on clinician assessment and not structured interview. Mood assessments were self-reported rather than clinician-administered. Suicidal ideation was more frequently observed than suicidal behavior (23/272 visits where outcome positive). Conclusions: Depression represents the primary mood state accounting for suicide risk in bipolar disorder. Co-occurring symptoms of mania (mixed symptoms) do not appear to convey an elevated risk for suicidal ideation or behavior beyond that explained by the depressive symptoms alone.
Aims: Antidepressants are common in bipolar disorder (BD), but controversial due to questionable efficacy/tolerability. We assessed baseline antidepressant use/depression associations in BD. Methods: Stanford BD Clinic outpatients, enrolled during 2000-2011, assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation, were monitored up to two years with the STEP-BD Clinical Monitoring Form while receiving naturalistic expert treatment. Prevalence/correlates of baseline antidepressant use in recovered (euthymic >= 8 weeks)/depressed patients were assessed. Kaplan-Meier survival analyses assessed times to depressive recurrence/recovery in patients with/without baseline anti-depressant use, and Cox Proportional Hazard regression analyses assessed covariate effects. Results: Baseline antidepressant use was significantly (albeit without Bonferroni multiple comparison correction) less among 105 recovered (31.4%) versus 153 depressed (44.4%) patients, and among recovered patients (again without Bonferroni correction), associated with Caucasian race, earlier onset, worse Clinical Global Impression scores, and hastened depressive recurrence (only if mood elevation episodes were not censored), driven by lifetime anxiety disorder, and more (even with Bonferroni correction) bipolar II disorder, lifetime anxiety and eating disorders, and core psychotropics. Baseline antidepressant use among depressed patients was associated with significantly (again without Bonferroni correction) older age, female gender, and more (even with Bonferroni correction) anxiolytics/hypnotics, complex pharmacotherapy, and core psychotropics, but no other unfavorable illness characteristic/current mood symptom, and not time to depressive recovery. Limitations: Tertiary BD clinic referral sample receiving open naturalistic expert treatment. Analyses without/with Bonferroni correction. Conclusions: Additional research is required to assess the complex associations between baseline antidepressant use and longitudinal depressive burden in BD.
Purpose: To retrospectively assess lurasidone effectiveness/efficacy/tolerability in bipolar disorder (BD) patients. Methods: Outpatients assessed with Systematic Treatment Enhancement Program for BD Affective Disorders Evaluation received naturalistically administered (primarily adjunctive) open lurasidone while monitored at visits with the Systematic Treatment Enhancement Program for BD Clinical Monitoring Form. Results: Sixty-one patients (32 type I, 26 type II, 3 type not otherwise specified; mean SD age, 45.1 +/- 14.0 years; 63.9% were female) received lurasidone with 3.1 +/- 1.4 (2 in 88.5%, monotherapy in only 3.3%) other nonanxiolytic/hypnotic prescription psychotropics, started during syndromal depression in 57.4%, subsyndromal depression in 23.0%, and euthymia in 19.7%. Lurasidone was taken for median 126 days, with final dose 55.6 +/- 30.8 mg/d. By final visit taking lurasidone, syndromal depression rate decreased by nearly one-half to 31.1%, and euthymia rate more than doubled to 42.6%, whereas subsyndromal depression rate was unchanged at 23.0%. Clinical Global Impressions-BD-Overall Severity improved significantly only in patients with baseline syndromal depression. Seventy-seven percent of patients discontinued lurasidone after median 103 days, because of adverse events in 54.1% (most often akathisia, sedation/somnolence, nausea, and weight gain), inefficacy in 16.4%, and other reasons in 6.6%; 12.1% had equal to or greater than 7% weight gain, and 3.3% developed hypomania. Limitations to this study were the open design and demographically homogeneous (relatively affluent, predominantly white female) small sample taking complex pharmacotherapy. Conclusions: In American specialty clinic BD outpatients, adjunctive longer-term lurasidone commonly relieved syndromal depression and maintained euthymia, suggesting possible effectiveness/efficacy. However, lurasidone was discontinued in 54.1% because of adverse events, suggesting tolerability limitations in these challenging patients, nearly 90% of whom were already taking at least 2 other nonanxiolytic/hypnotic prescription psychotropics.
Although eating disorders (EDs) are common in bipolar disorder (BD), little is known regarding their longitudinal consequences. We assessed prevalence, clinical correlates, and longitudinal depressive severity in BD patients with vs. without EDs.
AIMS:Assess episode accumulation (≥ 10 prior mood episodes) associations with demographic/baseline clinical characteristics and mood episode recurrence/recovery in bipolar disorder (BD). METHODS:Stanford BD Clinic outpatients enrolled during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. Among recovered and syndromal mood episode patients, we assessed episode accumulation associations with demographic/baseline clinical characteristics and with recurrence/recovery (by Kaplan-Meier survival analyses, with mediators assessed with Cox Proportional Hazard Ratio (HR) analyses). RESULTS:Among all 450 BD outpatients, almost twice as many had versus lacked episode accumulation (65.8% versus 34.2%), which was less common among 92 recovered versus 193 syndromal mood episode patients (51.1% versus 69.9%). Among recovered patients, episode accumulation was associated with 14/18 (77.7%) demographic/other baseline clinical characteristics, and hastened mood episode recurrence. Among syndromal mood episode patients, episode accumulation was associated with 13/18 (72.2%) demographic/other baseline clinical characteristics, and delayed mood episode recovery. LIMITATIONS:American tertiary BD clinic referral sample. CONCLUSION:Studies are needed to confirm episode accumulation is associated with hastened mood episode recurrence and delayed mood episode recovery in BD, and to further explore its' associations with hastened mood elevation recurrence and delayed recovery from depressive and mood elevation episodes, considered separately.
AIMS:To assess differential relationships between lifetime anxiety disorder/current anxiety symptoms and longitudinal depressive severity in bipolar disorder (BD).METHODS:Stanford BD Clinic outpatients enrolled during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and followed with the STEP-BD Clinical Monitoring Form while receiving naturalistic treatment for up to two years. Baseline unfavorable illness characteristics/current mood symptoms and times to depressive recurrence/recovery were compared in patients with versus without lifetime anxiety disorder/current anxiety symptoms.RESULTS:Among 105 currently recovered patients, lifetime anxiety disorder was significantly associated with 10/27 (37.0%) demographic/other unfavorable illness characteristics/current mood symptoms/current psychotropics, hastened depressive recurrence (driven by earlier onset age), and a significantly (> two-fold) higher Kaplan-Meier estimated depressive recurrence rate, whereas current anxiety symptoms were significantly associated with 10/27 (37.0%) demographic/other unfavorable illness characteristics/current mood symptoms/current psychotropics and hastened depressive recurrence (driven by lifetime anxiety disorder), but only a numerically higher Kaplan-Meier estimated depressive recurrence rate. In contrast, among 153 currently depressed patients, lifetime anxiety disorder/current anxiety symptoms were not significantly associated with time to depressive recovery or depressive recovery rate.LIMITATIONS:American tertiary BD clinic referral sample, open naturalistic treatment.CONCLUSIONS:Research is needed regarding differential relationships between lifetime anxiety disorder and current anxiety symptoms and hastened/delayed depressive recurrence/recovery - specifically whether lifetime anxiety disorder versus current anxiety symptoms has marginally more robust association with hastened depressive recurrence, and whether both have marginally more robust associations with hastened depressive recurrence versus delayed depressive recovery, and related clinical implications.
Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients.
Background: Abnormal sleep duration (ASD, < 6 or 9 h) is common in bipolar disorder (BD), and often persists beyond acute mood episodes. Few longitudinal studies have examined the ASD's impact upon BD illness course. The current study examined the longitudinal impact of ASD upon bipolar depressive recurrence/recovery.Methods: Outpatients, referred to the Stanford BD Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation at baseline, and with the Clinical Monitoring Form at monthly follow-ups for up to two years of naturalistic treatment. Prevalence and clinical correlates of ASD in 93 recovered (euthymic 8 weeks) and 153 depressed BD patients were assessed. Kaplan-Meier analyses (Log-Rank tests) assessed relationships between baseline ASD and longitudinal depressive severity, with Cox Proportional Hazard analyses assessing potential mediators.Results: ASD was only half as common among recovered versus depressed BD outpatients, but was significantly associated with hastened depressive recurrence (Log-Rank p = 0.007), mediated by lifetime anxiety disorder and attenuated by lifetime history of psychosis, and had only a non-significant tendency towards association with delayed depressive recovery (Log-Rank p = 0.07). In both recovered and depressed BD outpatients, baseline ASD did not have significant association with any baseline BD illness characteristic.Limitations: Self-reported sleep duration. Limited generalizability beyond our predominately white, female, educated, insured American BD specialty clinic sample.Conclusions: Baseline ASD among recovered BD patients may be a risk marker for hastened depressive recurrence, suggesting it could be an important therapeutic target between mood episodes.
Pharmacotherapy of bipolar disorders is complex and rapidly evolving. Antipsychotics, antidepressants, anxiolytics, and new-generation anticonvulsants are commonly combined with traditional first-line mood stabilizers (lithium, valproate, carbamazepine) in clinical settings (American Psychiatric Association 2002; Ketter 2005; Suppes et al. 2005). Clinicians are challenged with integrating complex data regarding efficacy and adverse-effect profiles with pharmacological properties in efforts to provide safe, effective, state-of-the-art pharmacotherapy for patients with bipolar disorder. In this chapter we review the pharmacology of carbamazepine (CBZ) and its analog oxcarbazepine (OXC). In the past, CBZ was considered an alternative to lithium and valproate rather than a first-line intervention in the treatment of bipolar disorder (American Psychiatric Association 2002), largely owing to methodological limitations of early studies of efficacy in bipolar disorder, complexity of use due to adverse effects and drug–drug interactions, and lack of a U.S. Food and Drug Administration (FDA) indication for the treatment of bipolar disorder. CBZ received an indication for the treatment of acute manic and mixed episodes in bipolar disorder following evidence from two randomized double-blind, placebo-controlled, parallel-group studies in patients with bipolar disorder (Weisler et al. 2004, 2005). Importantly, in selected patients, CBZ and OXC may offer favorable efficacy and tolerability—in particular, less weight gain and metabolic problems—and thus can be important treatment alternatives (Akiskal et al. 2005). Likewise, the active monohydride metabolite of OXC, licarbazepine, and its prodrug, eslicarbazepine acetate (ESL), may have improved tolerability, although evidence of efficacy in bipolar disorder is lacking.
Background: Suicide attempts are common in patients with bipolar disorder (BD), and consistently associated with female gender and certain unfavorable BD illness characteristics. Findings vary, however, regarding effects of BD illness subtype and yet other illness characteristics upon prior suicide attempt rates. We explored the effects of demographics and BD illness characteristics upon prior suicide attempt rates in patients stratified by BD illness subtype (i.e., with bipolar I disorder (BDI) versus bipolar II disorder (BDII)).Methods: Outpatients referred to the Stanford BD Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD Affective Disorders Evaluation. Rates of prior suicide attempt were compared in patients with and without diverse demographic and BD illness characteristics stratified by BD subtype.Results: Among 494 BD outpatients (mean +/- SD age 35.6 +/- 13.1 years; 58.3% female; 48.6% BDI, 51.4% BDII), overall prior suicide attempt rates in were similar in BDI versus BDII patients, but approximately twice as high in BDI (but not BDI1) patients with compared to without lifetime eating disorder, and in BDII (but not BDI) patients with compared to without childhood BD onset. In contrast, current threshold level suicidal ideation and lifetime alcohol use disorder robustly but less asymmetrically increased prior suicide attempt risk across BD subtypes. Limitations: American tertiary bipolar disorder clinic referral sample, cross-sectional design.Conclusions: Further studies are needed to assess the extent to which varying clinical characteristics of samples of patients with BDI and BDII could yield varying prior suicide attempt rates in patients with BDI versus BDII.

OBJECTIVE:Although bipolar disorder (BD) is a common recurrent condition with highly heterogeneous illness course, data are limited regarding clinical implications of interactions between gender and onset age. We assessed relationships between onset age and demographic/illness characteristics among BD patients stratified by gender. METHODS:Demographic and unfavorable illness characteristics, descriptive traits, and clinical correlates were compared in 502 patients from Stanford University BD Clinic patients enrolled in the Systematic Treatment Enhancement Program for BD between 2000 and 2011, stratified by gender, across pre-, peri-, and post-pubertal (<12, 13-16, and >17 years, respectively) onset-age subgroups. RESULTS:Among 502 BD patients, 58.2% were female, of whom 21.9% had pre-pubertal, 30.7% peri-pubertal, and 47.4% post-pubertal onset. Between genders, although demographics, descriptive characteristics, and most clinical correlates were statistically similar, there were distinctive onset-age related patterns of unfavorable illness characteristics. Among females, rates of 6/8 primary unfavorable illness characteristics were significantly higher in pre-pubertal and peri-pubertal compared to post-pubertal onset patients. However, among males, rates of only 3/8 unfavorable illness characteristics were significantly higher in only pre-pubertal versus post-pubertal onset patients, and none between peri-pubertal versus post-pubertal onset patients. LIMITATIONS:Caucasian, insured, suburban, American specialty clinic-referred sample limits generalizability, onset age based on retrospective recall. DISCUSSION:We describe different phenotypic presentations across age at illness onset groups according to gender. Among females and males, peri-pubertal and post-pubertal onset age groups were more different and more similar, respectively. Further investigation is warranted to assess implications of gender-by-onset-age interactions to more accurately delineate distinctive BD phenotypes.
Aims: To assess second-generation antipsychotic (SGA) use, demographics, and clinical correlates in patients with bipolar I disorder (BDI) versus bipolar II disorder (BDII).Methods: Stanford Bipolar Disorder (BD) Clinic outpatients enrolled during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. Current SGA use, demographics, and clinical correlates were assessed for BDI versus BDII.Results: Among 503 BD outpatients, in BDI versus BDII, SGA use was more than twice as common (44.0% versus 21.2%), and doses were approximately twice as high. BDI patients taking (N = 107) versus not taking (N = 136) SGAs less often had current full time employment and college degree; and more often had lifetime psychiatric hospitalization, current depression, and current complex pharmacotherapy, and had a higher mean current Clinical Global Impression for Bipolar Version Overall Severity score, and these persisted significantly after covarying for employment and education. Prior psychiatric hospitalization was the most robust correlate of SGA use in BDI patients. In contrast, these demographic and clinical correlates of SGA use were not statistically significant among patients with BDII, although BDII (but not BDI) patients taking (N = 55) versus not taking (N = 205) SGAs were more likely to have current mood stabilizer use (67.3% versus 51.7%).Limitations: American tertiary bipolar disorder clinic referral sample, cross-sectional design.Conclusions: Current SGA use was robustly associated with prior psychiatric hospitalization in BDI and to a more limited extent with current mood stabilizer use in BDII. SGA use associations with other unfavorable illness characteristics in BDI were less robust. (C) 2016 Elsevier Ltd. All rights reserved.
ObjectiveAssess strengths and limitations of mixed bipolar depression definitions made more inclusive than that of the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM‐5) by requiring fewer than three ‘non‐overlapping’ mood elevation symptoms (NOMES).MethodAmong bipolar disorder (BD) out‐patients assessed with Systematic Treatment Enhancement Program for BD (STEP‐BD) Affective Disorders Evaluation, we assessed prevalence, demographics, and clinical correlates of mixed vs. pure depression, using less inclusive (≥3 NOMES, DSM‐5), more inclusive (≥2 NOMES), and most inclusive (≥1 NOMES) definitions.ResultsAmong 153 depressed BD, compared to less inclusive DSM‐5 threshold, our more and most inclusive thresholds, yielded approximately two‐ and five‐fold higher mixed depression rates (7.2%, 15.0%, and 34.6% respectively), and important statistically significant clinical correlates for mixed compared to pure depression (e.g. more lifetime anxiety disorder comorbidity, more current irritability), which were not significant using the DSM‐5 threshold.ConclusionFurther studies assessing strengths and limitations of more inclusive mixed depression definitions are warranted, including assessing the extent to which enhanced statistical power vs. other factors contributes to more vs. less inclusive mixed bipolar depression thresholds having more statistically significant clinical correlates, and whether ‘overlapping’ mood elevation symptoms should be counted.
