Key Findings

• Over two years, the quality improvement (QI) programs improved the quality of care that patients received.
• The programs also improved patients' health and quality of life and increased the amount of time that patients worked.
• The programs modestly increased health care costs but, compared with other accepted interventions, were cost-effective.
• The programs, particularly QI therapy, reduced ethnic disparities in health outcomes.
• While the main effects on quality of care and psychological health were gone nearly a decade out, there were still indirect effects on reduced long-term depression and lingering secondary effects on barriers to care, problems in coping with stress, and perceived discrimination from one period of improving care for depression.
