The thesis touches the field of diabetes, which presents a great challenge for successful management. There are a number of services in the world which help patients and healthcare professionals who are monitoring and assisting the patient. One of these services in Slovenia is the ‘Center za zdravje na daljavo (CEZAR)’, which operates within the GH Slovenj Gradec. The aim of the work was to create a portal that allows the patient to access the medical documentation at the center CEZAR. Based on the analysis, we made a portal design that addresses our needs. It is developed with the help of CMS Drupal technology, and the key product is a module which enables communication with a telemedicine center and contains blocks for data review.
