Collaborative Care for Treatment of Depression and Anxiety

We will answer the question: does a collaborative care model in primary care clinics improve outcomes for patients with depression and/or anxiety? Specific components of the model include:

• Patient-centered team care - virtual care management to support patient outreach, follow-up, and navigation to appropriate care settings, based on patient risk. Shared care plans with primary care and behavioral health providers, with a focus on patient preferences (e.g., short-term therapy, medications, or both) and fostering engagement in treatment.
• Population-based care - Automated workflows for population-based outreach with the Patient Health Questionnaire 9-item (PHQ9) and Generalized Anxiety Disorder 7-item (GAD7) questionnaires after diagnosis and treatment initiation for more accurate and comprehensive assessment of patient improvement. This also includes automating risk-based routing of PHQ9 results to the collaborative care team to triage patients into the most appropriate care settings and developing similar automated risk-based routing procedures for GAD7 results.
• Measurement-based treatment to target - provide short-term psychotherapy and/or pharmacotherapy with a focus on measuring treatment response with the PHQ9 and/or GAD7 to guide treatment adjustments.
• Evidence-based care - provide short-term Problem-Solving Treatment-Primary Care (PST-PC), Behavioral Activation (BA), and/or medications shown to be effective for patients in primary care settings. These evidence-based interventions will include patient engagement strategies and be applicable to diverse patient populations.
• Accountable care - The collaborative care provider team will be accountable for quality of care and clinical outcomes for the patients they serve, not just the volume of care provided.

A cluster randomized design will be used to compare depression and anxiety outcomes for at least two randomly selected KPCO primary care clinics that implement collaborative care to those clinics that provide care as usual. This design will allow us to study the effectiveness of the collaborative care model and its potential for dissemination across Kaiser Permanente regions.
