Objective: This study examined organizational variability of process-of-care and depression outcomes at eight community health centers (CHCs) in the years following implementation of collaborative care (CC) for depression. Methods: The authors used 8 years of observational data for 13,362 unique patients at eight CHCs that participated in Washington State’s Mental Health Integration Program. Organization-level changes in depression and process-of-care outcomes over time were studied. Results: On average, depression outcomes improved for the first 2 years before improvement slowed, peaking at year 5. Significant organization-level variation was noted in outcomes. Improvements in depression outcomes tended to follow process-of-care measures. Conclusions: Findings suggest that it may take 2 years after implementation of CC to fully observe depression outcome improvement at an organization level. Substantial variation between organizations in depression outcomes over time suggests that sustained attention to processes of care may be necessary to maintain initially achieved gains.
