Entrepreneurs in integrated care face some of the same challenges in empirically demonstrating impact, regardless of the model of care they espouse. In this editorial, 2 leading model developers reflect on the state of the science in primary care integration, including research gaps and promising research underway. We asked these leaders to discuss conceptual areas of shared concern, and we present those with reference to the metaphor of the translational research bridge. Their insights resonate with one another and suggest a role for collaboration to advance empirical support for the implementation of integrated care.
