Collaborative Care for Depression and Anxiety Disorders in Patients With Recent Cardiac Events The Management of Sadness and Anxiety in Cardiology (MOSAIC) Randomized Clinical Trial

IMPORTANCE Depression and anxiety are associated with adverse cardiovascular outcomes in patients with recent acute cardiac events. There has been minimal study of collaborative care (CC) management models for mental health disorders in high-risk cardiac inpatients, and no prior CC intervention has simultaneously managed depression and anxiety disorders. OBJECTIVE To determine the impact of a low-intensity CC intervention for depression, generalized anxiety disorder, and panic disorder among patients hospitalized for an acute cardiac illness. DESIGN, SETTING, AND PARTICIPANTS Single-blind randomized clinical trial, with study assessors blind to group assignment, from September 2010 through July 2013 of 183 patients admitted to inpatient cardiac units in an urban academic general hospital for acute coronary syndrome, arrhythmia, or heart failure and found to have clinical depression, generalized anxiety disorder, or panic disorder on structured assessment. INTERVENTIONS Participants were randomized to 24 weeks of a low-intensity telephone-based multicomponent CC intervention targeting depression and anxiety disorders (n = 92) or to enhanced usual care (serial notification of primary medical providers; n = 91). The CC intervention used a social work care manager to coordinate assessment and stepped care of psychiatric conditions and to provide support and therapeutic interventions as appropriate. MAIN OUTCOMES AND MEASURES Improvement in mental health-related quality of life (Short Form-12 Mental Component Score [SF-12 MCS]) at 24 weeks, compared between groups using a random-effects model in an intent-to-treat analysis. RESULTS Patients randomized to CC had significantly greater estimated mean improvements in SF-12 MCS at 24 weeks (11.21 points [from 34.21 to 45.42] in the CC group vs 5.53 points [from 36.30 to 41.83] in the control group; estimated mean difference, 5.68 points [95% CI, 2.14-9.22]; P = .002; effect size, 0.61). Patients receiving CC also had significant improvements in depressive symptoms and general functioning, and higher rates of treatment of a mental health disorder; anxiety scores, rates of disorder response, and adherence did not differ between groups. CONCLUSIONS AND RELEVANCE A novel telephone-based, low-intensity model to concurrently manage cardiac patients with depression and/or anxiety disorders was effective for improving mental health-related quality of life in a 24-week trial.

Positive psychological attributes and cardiac outcomes: associations, mechanisms, and interventions.

BACKGROUND Intervention research at the intersection of psychiatry and cardiology has primarily focused on the relationship between negative psychological syndromes (e.g., depression) and cardiac outcomes, with less emphasis on positive psychological attributes, such as optimism, gratitude, and well-being, as they relate to cardiac disease. METHODS Literature is reviewed in three specific areas regarding positive attributes and cardiac disease: (1) associations between positive attributes and cardiac outcomes, (2) potential mechanisms-both behavioral and physiologic-by which positive psychological states may impact cardiovascular health, and (3) interventions aimed at cultivating positive psychological attributes in healthy and medically ill persons. RESULTS There is significant evidence that positive psychological attributes--especially optimism--may be independently associated with superior cardiac outcomes. Positive attributes appear to be associated with increased participation in cardiac health behaviors (e.g., healthy eating, physical activity) linked to beneficial outcomes; data linking positive psychological states and biomarkers of cardiac health (e.g., inflammatory markers) is mixed but suggests a potential association. Positive psychological interventions have consistently been associated with improved well-being and reduced depressive symptoms, though there have been few such studies in the medically ill. CONCLUSIONS These findings regarding the relationship between positive psychological attributes and cardiac health are promising and suggest that positive psychology interventions may be worth study in this population. However, questions remain about the strength and specificity of these relationships, the most salient positive psychological attributes, and the impact of positive psychological interventions on health outcomes in cardiac patients.

Feasibility and utility of positive psychology exercises for suicidal inpatients

OBJECTIVE The objective was to assess the feasibility and acceptability of nine positive psychology exercises delivered to patients hospitalized for suicidal thoughts or behaviors, and to secondarily explore the relative impact of the exercises. METHOD Participants admitted to a psychiatric unit for suicidal ideation or behavior completed daily positive psychology exercises while hospitalized. Likert-scale ratings of efficacy (optimism, hopelessness, perceived utility) and ease of completion were consolidated and compared across exercises using mixed models accounting for age, missing data and exercise order. Overall effects of exercise on efficacy and ease were also examined using mixed models. RESULTS Fifty-two (85.3%) of 61 participants completed at least one exercise, and 189/213 (88.7%) assigned exercises were completed. There were overall effects of exercise on efficacy (χ(2)=19.39; P=.013) but not ease of completion (χ(2)=11.64; P=.17), accounting for age, order and skipped exercises. Effect (Cohens d) of exercise on both optimism and hopelessness was moderate for the majority of exercises. Exercises related to gratitude and personal strengths ranked highest. Both gratitude exercises had efficacy scores that were significantly (P=.001) greater than the lowest-ranked exercise (forgiveness). CONCLUSION In this exploratory project, positive psychology exercises delivered to suicidal inpatients were feasible and associated with short-term gains in clinically relevant outcomes.

Positive Psychological Interventions for Patients with Type 2 Diabetes: Rationale, Theoretical Model, and Intervention Development

Most patients with type 2 diabetes (T2D) have suboptimal adherence to recommended diet, physical activity, and/or medication. Current approaches to improve health behaviors in T2D have been variably effective, and successful interventions are often complex and intensive. It is therefore vital to develop interventions that are simple, well-accepted, and applicable to a wide range of patients who suffer from T2D. One approach may be to boost positive psychological states, such as positive affect or optimism, as these constructs have been prospectively and independently linked to improvements in health behaviors. Positive psychology (PP) interventions, which utilize systematic exercises to increase optimism, well-being, and positive affect, consistently increase positive states and are easily delivered to patients with chronic illnesses. However, to our knowledge, PP interventions have not been formally tested in T2D. In this paper, we review a theoretical model for the use of PP interventions to target health behaviors in T2D, describe the structure and content of a PP intervention for T2D patients, and describe baseline data from a single-arm proof-of-concept (N = 15) intervention study in T2D patients with or without depression. We also discuss how PP interventions could be combined with motivational interviewing (MI) interventions to provide a blended psychological-behavioral approach.

A double-blind, placebo-controlled study of the impact of galantamine on anterograde memory impairment during electroconvulsive therapy.

Background Electroconvulsive therapy (ECT) continues to be an effective treatment option for patients who fail to respond to pharmacological interventions, are unable to tolerate medications, and show a suboptimal response to behavioral and psychotherapeutic treatments. However, risks for cognitive impairment may contribute to some patients’ refusal of ECT. Methods The present study examined galantamine as a pharmacological intervention to reduce cognitive adverse effects from ECT. Thirty-nine inpatients diagnosed with major depressive disorder; bipolar disorder, depressed type; or schizoaffective disorder, depressed type and admitted for ECT were randomized to galantamine or placebo. Study drugs were initiated 24 to 48 hours before starting ECT and continued throughout the course of ECT. A neuropsychological test battery was administered at baseline and 24 to 48 hours after completing a course of ECT treatments. Depression severity was monitored using the 17-item Hamilton Rating Scale for Depression and Clinical Global Impression Scale at baseline, weekly, and end point. Self-rated adverse effects were monitored weekly. Results Thirty participants (12 patients in the galantamine group, 18 patients in the placebo group) had both pretreatment and posttreatment neuropsychological ratings. Those in the galantamine group scored significantly higher at discharge for delayed memory (t28 = 2.44, P < 0.05). Hierarchical regressions examined if treatment condition predicted changes in delayed memory scores from baseline to discharge. Inclusion of the treatment condition in the final model made a significant incremental improvement in prediction (&Dgr;R2 = 0.12, F1,27 change = 4.65, P < 0.05; &bgr; = 0.37, t = 2.16, P < 0.05). Galantamine was well tolerated with no clinically significant bradycardia or prolonged paralysis when administered with ECT. Conclusions Galantamine may be protective against impairment in retention of new learning. Galantamine exhibited minimal adverse effects and was safe when administered during ECT. The present findings require replication by future researchers using larger samples before broad conclusions can be drawn.

Design and baseline data from the Management of Sadness and Anxiety in Cardiology (MOSAIC) randomized controlled trial

BACKGROUND Depression and anxiety in cardiac patients are independently associated with adverse cardiovascular outcomes, including mortality. Collaborative care (CC) programs, which use care managers to assess patients, coordinate care, and perform therapeutic interventions, have proven effective in managing depression in this population. However, no prior CC intervention has simultaneously managed depression and anxiety disorders, and there has been minimal study of CC in high-risk cardiac inpatients. MATERIALS AND METHODS The Management of Sadness and Anxiety in Cardiology (MOSAIC) study was a prospective randomized trial of a low-intensity CC intervention, compared to enhanced usual care, for patients hospitalized for acute coronary syndrome, heart failure, or arrhythmia, and diagnosed with depression, generalized anxiety disorder (GAD), or panic disorder (PD). The primary outcome measure for MOSAIC was mental health-related quality of life (HRQoL), measured using the Medical Outcomes Study Short Form-12. Additional outcomes included psychological, functional, and medical outcomes, including rehospitalizations. RESULTS A total of 183 eligible participants were enrolled (92 collaborative care, 91 enhanced usual care); 94% of depressed patients reported being depressed for >1month, and 53% of those with GAD reported clinically significant anxiety for >1year. One hundred thirty-three patients had depression, 118 had GAD, and 19 had PD; 74 participants (40%) had two or more of the disorders. CONCLUSION The MOSAIC trial will provide data regarding whether an intervention that concurrently manages these common psychiatric disorders results in meaningful improvements in HRQoL, psychiatric symptoms, and medical outcomes in cardiac patients at high risk for adverse outcomes.

Rapid improvement of depression and psychotic symptoms in Huntington's disease: a retrospective chart review of seven patients treated with electroconvulsive therapy.

Many patients with Huntingtons disease (HD) develop psychiatric symptoms such as depression and psychosis. For severe symptoms, electroconvulsive therapy (ECT) can be a valuable treatment. In this case series, we identified seven patients with HD who received ECT at Massachusetts General Hospital in the past 20 years. In all cases, ECT was well tolerated and produced improvement in psychiatric and behavioral symptoms. Our case series supports the hypothesis of a positive risk-benefit ratio for ECT in patients with HD and severe depression or psychosis.

Positive psychological states and health behaviors in acute coronary syndrome patients: A qualitative study

Positive psychological states are linked to superior cardiac outcomes, possibly mediated through increased participation in health behaviors. Trained study staff conducted in-depth semi-structured interviews in the hospital and 3 months later for 34 patients diagnosed with an acute coronary syndrome. These interviews focused on positive psychological states, cardiac health behaviors, and their connection; the interviews were transcribed and independently coded using directed content analysis. Both optimism and positive affect were associated with completion of physical activity and healthy eating in a bidirectional manner. In contrast, gratitude, while common, was infrequently linked to completion of health behaviors.

Feasibility and Acceptability of a Positive Psychological Intervention for Patients With Type 2 Diabetes

OBJECTIVE Positive psychological attributes (eg, optimism) have been associated with a healthier lifestyle and superior medical outcomes in patients with type 2 diabetes; however, there has been minimal study of behavioral interventions that target positive psychological constructs in this population. Accordingly, we developed a novel, telephone-based, 12-week positive psychology intervention and assessed its feasibility and short-term impact in adults with type 2 diabetes and suboptimal health behavior adherence. METHOD This was a pilot and feasibility study in adult inpatients and outpatients at an urban academic medical center recruited between December 2013 and December 2014. Adult patients with (1) type 2 diabetes (meeting American Diabetes Association criteria, eg, glycated hemoglobin A1c [HbA1c] > 6.5% or fasting glucose > 126 mg/dL) and (2) suboptimal adherence (score < 15/18 on the Medical Outcomes Study Specific Adherence Scale items for medication, diet, and exercise) were eligible. Participants received a positive psychology manual, completed exercises (eg, writing a gratitude letter, performing acts of kindness), and reviewed these activities by phone with a study trainer over the 12-week study period. Feasibility and acceptability were assessed via exercise completion rates and postexercise ratings of ease/utility on 0-10 Likert scales. Longer-term efficacy was explored by examining changes in psychological states and health behaviors from baseline to 12 weeks using random-effects regression models and estimates of effect size. RESULTS A total of 15 participants enrolled; 12 participants provided complete baseline and follow-up data and were included in the analyses. Over 90% of these participants completed at least 2 exercises, and 75% completed a majority of the exercises. Participants rated the exercises as helpful (mean = 7.8/10) and easy to complete (mean = 7.1/10), and they reported improvements in optimism, gratitude, depression, anxiety, physical function, self-care, and health behaviors (Cohen d = 0.28-1.00). CONCLUSION A positive psychology intervention for suboptimally adherent patients with type 2 diabetes was feasible, acceptable, and associated with broad pre-post psychological and health behavior improvement in a small initial study. Further testing of this promising intervention is warranted. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT02736084.

Relationship of optimism and suicidal ideation in three groups of patients at varying levels of suicide risk.

Optimism has been associated with reduced suicidal ideation, but there have been few studies in patients at high suicide risk. We analyzed data from three study populations (total N = 319) with elevated risk of suicide: (1) patients with a recent acute cardiovascular event, (2) patients hospitalized for heart disease who had depression or an anxiety disorder, and (3) patients psychiatrically hospitalized for suicidal ideation or following a suicide attempt. For each study we analyzed the association between optimism (measured by the Life-Orientation Test-Revised) and suicidal ideation, and then completed an exploratory random effects meta-analysis of the findings to synthesize this data. The meta-analysis of the three studies showed that higher levels of self-reported optimism were associated with a lower likelihood of suicidal ideation (odds ratio [OR] = .89, 95% confidence interval [CI] = .85-.95, z = 3.94, p < .001), independent of age, gender, and depressive symptoms. This association held when using the subscales of the Life Orientation Test-Revised scale that measured higher optimism (OR = .84, 95% CI = .76-.92, z = 3.57, p < .001) and lower pessimism (OR = .83, 95% CI = .75-.92], z = 3.61, p < .001). These results also held when suicidal ideation was analyzed as an ordinal variable. Our findings suggest that optimism may be associated with a lower risk of suicidal ideation, above and beyond the effects of depressive symptoms, for a wide range of patients with clinical conditions that place them at elevated risk for suicide.
