The MedSERVE service has been developed to exchange patient related information between senders (hospitals, clinical laboratories, medical specialists,...) and their contacts (GPs, hospitals, medical specialists...), by means of a telephone line (direct connection with a modem or an internet connection) and all of this without any manual intervention.

Prescribe is an essential source of scientific information build in a prescription software package that can be connected to any electronic health record system.

MedSHARE aims at offering healthcare professionals a tool to substantially improve the quality and efficiency of care delivery. The service is based on the storage of an excerpt of the patient's Electronic HealthCare Record (EHCR) - with the patients consent - on a secured server. Those excerpts can then be consulted by entitled healthcare professionals, when needed, through the internet (cfr. principle PC-Banking).
