The main premise of the iCDM is that users will log-on on a regular basis and enter data related to how they are feeling and some physical measures (such as body weight, blood sugar, blood pressure, as relevant). Based on answers to these questions, the website may show a message either saying everything is fine or give a warning, informing the patient of their answers and that a nurse will be contacting them on the next business day. If the nurse receives an alert in his/her email inbox, he/she will telephone the patient within approximately 24 hours to discuss the entered data. The nurse may also direct the patient to discuss with the dietician or exercise specialist, or tell them that it is probably best for them to visit their physician for their symptoms.
