In this paper, we do a brief literature review on portals and their stakeholders. Health portal stakeholders are identified, within their internal and external action to the system. It is also reported the results of an analysis made to a number of European, United States and Australia health portals. In this paper we propose a conceptual model of a patient health portal based on a calendar perspective. Users’ needs are reflected in this conceptual model. We also describe the implementation of prototype based on the conceptual model. The prototype was built in an open source content management system (Drupal). Our study does also include a statistical analysis of the preliminary results of a survey to a group of users.
