The increasingly connected world of health care delivery relies on an expanding frontier of multi-stakeholder structures and processes, from interdisciplinary patient-centered care teams, to virtual accountable care organizations (ACOs), to complex community-level interventions. This session highlights recent advances in applying social network analysis (SNA) methods to study the implementation and impact of these types of innovations. This methods workshop examines the benefits and limits of novel SNA applications based on the expanding availability of large, linkable electronic clinical and administrative data sources with dependent data structures. This paper profiles examples of using SNA principles and methods to study the implementation and impact of multi-organizational public health delivery strategies.
