Does integrated care improve treatment for depression? A systematic review.

Care management-based interventions promoting integrated care by combining primary care with mental health services in a coordinated and colocated manner are increasingly popular; yet, the benefits of specific approaches are not well established. We conducted a systematic review of integrated care trials in US primary care settings to assess whether the level of integration of provider roles or care process affects clinical outcomes. Although most trials showed positive effects, the degree of integration was not significantly related to depression outcomes. Integrated care appears to improve depression management in primary care patients, but questions remain about its specific form and implementation.
