Integrated Care for Older Adults With Major Depression and Physical Multimorbidity - The I-CONNECT

Mood disorders, including depression and bipolar disorder, are common in older adults and frequently occur alongside multiple long-term physical health problems. This combination worsens quality of life, raises mortality risk, and increases healthcare use and costs. Despite the high burden, healthcare systems often provide fragmented care, with limited coordination between providers and underuse of mental health resources. I-CONNECT is a person-centered integrated care model designed to address these challenges. It combines professional care coordination with structured medication review, active involvement of general practitioners, psychiatrists, pharmacists, and specialists, and support for self-management through shared decision-making. By bridging primary and mental healthcare, the model seeks to reduce fragmentation, strengthen continuity of care, and improve outcomes for older adults with complex needs. Study Objectives The primary objective is to test whether I-CONNECT improves overall health outcomes compared with usual care. Secondary objectives are to examine participants' experiences of care, the burden of managing multiple health problems, and the impact on healthcare utilization. Hypothesis The investigators hypothesize that the I-CONNECT intervention will: Improve both mental and physical health outcomes, Reduce treatment burden and stress for participants, Enhance satisfaction with care, and Support a more efficient use of healthcare resources. Implementation Evaluation In addition to effectiveness, the study will assess how I-CONNECT is implemented. Process measures will include fidelity to the care model, the amount of intervention delivered, and outcomes of medication reviews. Qualitative feedback from participants and providers will help identify barriers and facilitators to scale-up and sustainability.
