Building a model of health technology assessment cooperation: lessons learned from EUnetHTA joint action 3.

These learnings coming from the experiences of the EUnetHTA JA3 are useful to inform discussions on a European Union regulation for HTA cooperation as well as subsequent work to set up the structures that will be defined in the regulation. The findings also have broader applicability and are relevant to individuals, groups, and organizations setting up HTA programs or establishing their own international collaborations.
