In Denmark, care of elderly people involves numerous and relatively autonomous care providers, including care centers, activity centers, physiotherapists, doctors, and other specialists. However, due to a poor coordination of activities, many elderly experience a lack of continuity of care, missed appointments, and general discomfort. In this poster we report on preliminary findings from a project aimed at creating improved IT support for coordination of care for the elderly in a Danish municipality. We propose that in order to successfully support heterogeneous collaboration, our system must address the disruptions in the existing routines, minimize the inherent articulation work, and coherently unify their coordination mechanisms.
