[Impact of a regional pharmacovigilance network on notification of adverse drug reactions: results at 3 years]. / Impact de la mise en place d'un réseau régional de pharmacovigilance sur la notification d'effets indésirables : bilan à 3 ans.

AIM: To stimulate spontaneous reporting of adverse drug reactions and to enable information sharing on drug's safety between Rennes Pharmacovigilance Regional Center and hospitals of its territory. METHODS: After having outlined objectives of the network to 11 major public institutions, the network was launched. It is coordinated by a dedicated pharmacist thanks to animation of monthly videoconference and diffusion of a quarterly newsletter. It relies on a local correspondent in each hospital who disseminates information to healthcare professionals and becomes their local contact for pharmacovigilance. RESULTS: The quality and usefulness of information sharing are emphasized by every one. We observed an increase in notifications and information requests multiplied by 3.4 and 2.4 % respectively between 2008 and 2013. CONCLUSIONS: The existence of a dedicated coordinator and implication of the correspondents are key elements enabling the network to be efficient. The increase of spontaneous notifications is noteworthy. The next step is to officially enlarge the network to private hospitals.
