eHealth platform is the official federal network in Belgium (created by law on 21 August 2008) devoted to a secure exchange of health data in many types of applications, such as health care purposes, simplification of administrative procedures and contribution to health policy. It implies a controlled access to decentralized databases and uses encrypted personal data. The national identification number has been chosen in order to authenticate the requester, the patient, and the receiver of information exchange. Authorizations have to be respected in order to obtain personal health data. Several questions are raised about its security: the lack of mandatory request for systematic journaling on accesses to the electronic patient record as well as the absence of explicit procedures for sanctions in case of unauthorized access, the new role of social security administration in managing security where a eHealth manager can be both judge and party (in the function of trusted third party for health data encryption and of a required lawyer for texts proposed by physicians to the Commission for the protection of private life). Another critic concerns the number of physicians in minority and the absence of patients' delegates in the eHealth Board. At a time when the patient is becoming a partner in the care team, should not he be the gate-keeper for the access to his own health record? How could networks help him to get the appropriate knowledge to contribute to care and to write his testament of life? Recent laws (on private life, patient rights and euthanasia) have contributed to a behavioural change in citizens and physician attitudes. Recommendations are made in order to improve the acceptability of eHealth platform. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.
