The use of CSCW systems in general involves complex informal communication between any users at different geographical places. An evaluation strategy of such systems has to be complex and focussing expecially on organisational and social aspects. The MOA-E evaluation modell is used for the evaluation of the use of videoconferences for health care planning. The case study has a multi-method approach with the use of participated observations, interviews and questionnaire. If the patients are not healthy enough personnel meetings are found as more appropriate than videoconferences for health care planning. The case study could be seen as a "critical case" for the use of videoconferences for elderly persons. The MOA-E model has contributed to a comprehensive understanding of the study.
