Healthcare policy in the United States (U.S.) has focused on promoting integrated healthcare to combat frag-
mentation (e.g., 1993 Health Security Act, 2010 Affordable Care Act). Researchers have responded by studying
coordination and developing typologies of integration. Yet, after three decades, research evidence for the benefits
of coordination and integration are lacking. We argue that research efforts need to refocus in three ways: (1) use
social networks to study relational coordination and integrated healthcare, (2) analyze integrated healthcare at
three levels of analysis (micro, meso, macro), and (3) focus on clinical integration as the most proximate impact
on patient outcomes. We use examples to illustrate the utility of such refocusing and present avenues for future
research
