Digital Clinical Practice Guidelines are commonly used in Danish health care. Planning and decision support are particularly important to patients with chronic diseases, who often are in contact with General Practitioners, Community Nurses and hospitals. In the Capital Region of Denmark the potential benefits of a planning and coordination module has been assessed in a full-scale simulation test including 18 health care professionals. The results showed that health care professionals can benefit from such a module. Furthermore unexpected new possible benefits concerning communication and quality management emerged during the test and potential new groups of users were identified.
