In this paper, we explore the use of videoconferences (VCs) in medical practice, and discuss how characteristics of the context affect the use of VCs. Forty-seven VCs were observed and videotaped, and 41 semi-structured interviews were conducted. Our findings suggest the use of VCs for acute collaborative work differs from the non-acute use of VCs. Non-acute use facilitates collaboration throughout the entire patient trajectory, while acute use facilitates medical problem solving in the moment. Strict specialization and division of labor reduce the cases to discuss and the discussion of complex treatment trajectories. Acute collaborative work is past and present work, while non-acute collaboration reflects past, present, and future treatment, that is, an overall trajectory.
