In this paper we discuss the fact that more and more patients are treated in their homes by a set of organizations, sometimes with different ownership, and how this fact places new and severe demands on health care and home service staff to communicate and collaborate. We point to the need for managers in different organizations to agree on ways of communicating and collaborating on the operational level and how this aspect needs to be considered during procurement of home care services. Most importantly, by reasoning around a set of problematic areas, we derive a set of related problems and suggest solutions for dealing with them. The solutions are a mix of organizational/administrative measures and IT support for communication and coordination.
