Consistently high-quality health care is expected throughout Europe while concurrently, financial resources of member states are decreasing. National Health Technology Assessment (HTA) institutes are informing evidence-based reimbursement decisions in the national context, leading to redundancies in HTA production and tying up limited resources. Since 2006, the European Union project, the European Network for HTA (EUnetHTA) is aiming at enhancing the efficient use of HTA resources and facilitating transnational collaboration. Our aim is to present previous experience in joint assessment of medical devices. Furthermore, possible benefits of European collaboration for stakeholders will be discussed.

Processes and challenges of the completed EUnetHTA Joint Action (JA) 2 are summarized and discussed. Benefits, aims and opportunities of the ongoing EUnetHTA JA 3 are described.

Six rapid assessments of medical devices, focusing on the assessment of effectiveness and safety, were published during EUnetHTA JA 2. Challenges in European medical device assessment encompass the choice of topics, the time point of assessments and the lack of European standards for systematic patient involvement. Characteristics of medical devices, like learning curves, call for monitoring them throughout their lifecycle.

The benefit of European collaboration for stakeholders is manifold: uncertainty with regard to actual added value of a technology is minimized through Early Dialogues; harmonized and transparent assessment processes increase the quality of reports; work division among HTA organizations allows a resource-efficient assessment of a bigger amount of technologies; patient involvement ensures consideration of patient relevant endpoints.

The importance of cross-border collaboration in HTA is shown in the continuation of the EUnetHTA project, which aims to sustainably strengthen international collaboration even after expiration of EU-funding.

European collaboration in medical device assessment can ensure cross-border health care and efficient cooperation of national health systems. The focus should be set on a wide implementation of jointly established methods and quality standards. The European collaboration can lead to a concrete benefit for various stakeholders.
