RecruitingBehavioural interventionA Patient Activation Approach to Implementing Depression Treatment in Cardiac PatientsThis study, which is being conducted as part of a Quality Improvement (QI) Initiative at Columbia University Irving Medical Center, will test whether delivering the iHeart DepCare tool increases real world reach and adoption of depression treatment among CHD patients. As part of the QI Initiative, Clinic Navigators will administer and record (in EPIC) depression screening in advance of primary care and cardiology appointments. Eligible patients with elevated depressive symptoms will be randomized to receive usual care vs. the iHeart DepCare tool in conjunction with brief motivational, technical and navigation support per patient preference. Aim 1: To test the effect of iHeart DepCare on depression treatment optimization (primary outcome) among coronary heart disease patients with elevated depressive symptoms. Aim 2: To explore the effect of iHeart DepCare on implementation outcomes, including provider referrals, among coronary heart disease patients with elevated depressive symptoms.
