The French National Authority for Health (HAS) has participated in the work of the European Network for Health Technology Assessment (EUnetHTA) since its creation in 2006. HAS has been an active partner in most EUnetHTA activities, and the lead partner of specific work packages.

This report presents a summary of the main contribution of HAS to the two latest EUnetHTA projects (Joint Action (JA) 1 and Joint Action 2 (JA2)), their impact on national production, and Health Technology Assessment (HTA) doers feedback as to the opportunities and challenges of participating to the network and using its outputs.

In JA 1 and JA 2 projects, HAS has: coordinated activities related to Early Dialogues and Additional Evidence Generation; coordinated the development of nine JA1 methodological guidelines for rapid relative effectiveness assessment (REA) of pharmaceuticals; participated in the production of two JA2 methodological guidelines; participated in the production of one JA1 and seven JA2 rapid REA reports, and two JA2 full HTAs.

The national uptake of EUnetHTA outputs included entire adoptation of one REA report and adaptation of another. EUnetHTA templates and methodological guidelines have been taken into account when updating or developing national ones. Thanks to the network, HAS HTA doers could exchange on ongoing assessments with European colleagues, have enhanced their methodological know-how and enlarged their professional network.

As for the challenges encountered, it turned out that the re-use of EUnetHTA reports for a technology of interest to HAS was not always possible, mainly due to discordances in deadlines or assessment questions between EUnetHTA and national productions.

HAS has actively participated in different EUnetHTA projects since the network's creation. This collaboration has enabled HAS HTA doers, among others, to optimize national assessments and enhance their methodological know-how.
