Collaborative Care Models for Mental Health Integration in Primary Care

Collaborative care models integrate mental health services within the primary care setting by establishing a structured, team-based approach. At its core, this model employs a care manager to coordinate stepped interventions under the supervision of a mental health specialist. Primary care providers, care managers and psychiatric consultants work in concert to identify, monitor and treat common mental disorders such as depression and anxiety, using measurement-based care to guide treatment to target. This approach has been adopted in diverse health systems to address the high prevalence of untreated mental disorders, reduce stigma and improve accessibility. Global implementation spans academic medical centres, community clinics and patient-centred medical homes, with adaptations for telecare, multimorbidity and population subgroups. Evidence to date demonstrates improved clinical outcomes, cost-effectiveness and enhanced patient satisfaction, making collaborative care a scalable strategy for strengthening mental health integration in general practice. The model’s emphasis on systematic follow-up, interdisciplinary communication and tailored psychological or pharmacological interventions underpins its success across varied health-system contexts.
