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.

Feasibility and Utility of Screening for Depression and Anxiety Disorders in Patients With Cardiovascular Disease

Background—Depression and anxiety in patients with cardiac disease are common and independently associated with morbidity and mortality. We aimed to explore the use of a 3-step approach to identify inpatients with cardiac disease with depression, generalized anxiety disorder (GAD), or panic disorder; understand the predictive value of individual screening items in identifying these disorders; and assess the relative prevalence of these disorders in this cohort. Methods and Results—To identify depression and anxiety disorders in inpatients with cardiac disease as part of a care management trial, an iterative 3-step screening procedure was used. This included an existing 4-item (Coping Screen) tool in nursing data sets, a 5-item screen for positive Coping Screen patients (Patient Health Questionnaire-2 [PHQ-2], GAD-2, and an item about panic attacks), and a diagnostic evaluation using PHQ-9 and the Primary Care Evaluation of Mental Disorders anxiety disorder modules. Overall, 6210 inpatients received the Coping Screen, 581 completed portions of all 3 evaluation steps, and 210 received a diagnosis (143 depression, 129 GAD, 30 panic disorder). Controlling for age, sex, and the other screening items, PHQ-2 items independently predicted depression (little interest/pleasure: odds ratio [OR]=6.65, P<0.001; depression: OR=5.24, P=0.001), GAD-2 items predicted GAD (anxious: OR=4.09, P=0.003; unable to control worrying: OR=10.46, P<0.001), and the panic item predicted panic disorder (OR=49.61, P<0.001). Conclusions—GAD was nearly as prevalent as depression in this cohort, and GAD-2 was an effective screening tool; however, panic disorder was rare. These results support the use of 2-step screening for depression and GAD beginning with a 4-item scale (GAD-2 plus PHQ-2). Clinical Trial Registration—Unique Identifier: NCT01201967.

Effects of Optimism and Gratitude on Physical Activity, Biomarkers, and Readmissions After an Acute Coronary Syndrome The Gratitude Research in Acute Coronary Events Study

Background—Positive psychological constructs, such as optimism, are associated with beneficial health outcomes. However, no study has separately examined the effects of multiple positive psychological constructs on behavioral, biological, and clinical outcomes after an acute coronary syndrome (ACS). Accordingly, we aimed to investigate associations of baseline optimism and gratitude with subsequent physical activity, prognostic biomarkers, and cardiac rehospitalizations in post-ACS patients. Methods and Results—Participants were enrolled during admission for ACS and underwent assessments at baseline (2 weeks post-ACS) and follow-up (6 months later). Associations between baseline positive psychological constructs and subsequent physical activity/biomarkers were analyzed using multivariable linear regression. Associations between baseline positive constructs and 6-month rehospitalizations were assessed via multivariable Cox regression. Overall, 164 participants enrolled and completed the baseline 2-week assessments. Baseline optimism was significantly associated with greater physical activity at 6 months (n=153; &bgr;=102.5; 95% confidence interval, 13.6–191.5; P=0.024), controlling for baseline activity and sociodemographic, medical, and negative psychological covariates. Baseline optimism was also associated with lower rates of cardiac readmissions at 6 months (n=164), controlling for age, sex, and medical comorbidity (hazard ratio, 0.92; 95% confidence interval, [0.86–0.98]; P=0.006). There were no significant relationships between optimism and biomarkers. Gratitude was minimally associated with post-ACS outcomes. Conclusions—Post-ACS optimism, but not gratitude, was prospectively and independently associated with superior physical activity and fewer cardiac readmissions. Whether interventions that target optimism can successfully increase optimism or improve cardiovascular outcomes in post-ACS patients is not yet known, but can be tested in future studies.

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.

Positive Psychology Interventions for Patients With Heart Disease: A Preliminary Randomized Trial

BACKGROUND Positive psychologic characteristics have been linked to superior cardiac outcomes. OBJECTIVE Accordingly, in this exploratory study, we assessed positive psychology interventions in patients who had recently undergone a procedure to treat cardiovascular disease. METHOD Participants were randomly assigned to receive 1 of 3 different 6-week face-to-face interventions or a wait-list control condition. We assessed intervention feasibility and compared changes in psychologic outcome measures postintervention (7wk) and at follow-up (15wk) between intervention and control participants. Across the interventions, 74% of assigned sessions were completed. RESULTS When comparing outcomes between interventions and control participants (N = 55 total), there were no between-group differences post-intervention, but at follow-up intervention participants had greater improvements in happiness (β = 14.43, 95% CI: 8.66-20.2, p < 0.001), depression (β = -3.87, 95% CI: -7.72 to 0.02, p = 0.049), and hope (β = 7.12, 95% CI: 1.25-13.00, p =0.017), with moderate-large effect sizes. Efficacy of the 3 interventions was similar. CONCLUSIONS Future studies are needed to identify an optimal positive psychology intervention for cardiac patients.

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.

Cost-Effectiveness of a Collaborative Care Depression and Anxiety Treatment Program in Patients with Acute Cardiac Illness

OBJECTIVE To use data from a randomized trial to determine the cost-effectiveness of a collaborative care (CC) depression and anxiety treatment program and to assess effects of the CC program on health care utilization. METHODS The CC interventions impact on health-related quality of life, depression-free days (DFDs), and anxiety-free days (AFDs) over the 24-week postdischarge period was calculated and compared with the enhanced usual care (EUC) condition using independent samples t tests and random-effects regression models. Costs for both the CC and EUC conditions were calculated on the basis of staff time, overhead expenses, and treatment materials. Using this information, incremental cost-effectiveness ratios were calculated. A cost-effectiveness acceptability plot was created using nonparametric bootstrapping with 10,000 replications, and the likelihood of the CC interventions cost-effectiveness was assessed using standard cutoffs. As a secondary analysis, we determined whether the CC intervention led to reductions in postdischarge health care utilization and costs. RESULTS The CC intervention was more costly than the EUC intervention (
