      Over-reliance on decontextualized, standardized implementation of efficacy evidence has contributed to slow integration of evidence-based interventions into health policy and practice. This article describes an “evidence integration triangle” (EIT) to guide translation, implementation, prevention efforts, comparative effectiveness research, funding, and policymaking. The EIT emphasizes interactions among three related components needed for effective evidence implementation: (1) practical evidence-based interventions; (2) pragmatic, longitudinal measures of progress; and (3) participatory implementation processes. At the center of the EIT is active engagement of key stakeholders and scientific evidence and attention to the context in which a program is implemented. The EIT model is a straightforward framework to guide practice, research, and policy toward greater effectiveness and is designed to be applicable across multiple levels—from individual-focused and patient–provider interventions, to health systems and policy-level change initiatives.
