The Bypassing the Blues trial: Collaborative care for post-CABG depression and implications for future research

ABSTRACT

Depressive symptoms are reported by up to one-half of patients following coronary artery bypass graft (CABG) surgery, and are associated with numerous adverse outcomes, including poorer health-related quality of life, worse functional status, and delayed recovery. Strategies to detect and then manage depression in CABG patients and in cardiac populations are of great interest given the potential for depression treatment to reduce cardiovascular morbidity. Yet, many tested interventions have had little or no effect on mood symptoms in cardiac patients. “Collaborative care” is a safe and proven-effective strategy for treating depression in concert with patients’ primary care physicians; however, it had not been tested previously in patients with cardiac disease. This article presents the design and main outcome findings from the National Institutes of Health–funded Bypassing the Blues study, the first trial to examine the impact of a collaborative care strategy for treating depression among patients with cardiac disease, and our efforts to improve upon and expand the model for testing in other cardiac conditions.
