@ 31st EGOS Colloquium, July 2–4, 2015, Athens, Greece Abstract: In this paper, we explore field emergence, as it happens, aiming to enrich the theoretical understanding of this understudied phenomena and of institutional complexity. Our inductive case study is the nascent field of collaborative digital health technologies, which we follow from 2007 to present. We employ an institutional logics perspective, and drawing on existing theorization of field emergence, we point out the complex intertwine of logics and stakeholders as they reveal in time. Although preliminary, our findings present four distinct emergence phases: ingenuous age, legitimation, mobilization and stabilization, along with particular aspects like the role of legitimizing actors and the granularity of the field during mobilization. Additionally, we discuss digital technologies as enablers and material mediators of institutional change, and highlight the emerging role of the hybrid patient, with practical implications for the evolution of healthcare, as we know it.
