The TEHDAS2 project has officially launched a public consultation to refine the guidelines and technical specifications for the secondary use of health data in Europe. This consultation is a crucial part of aligning the project’s objectives with the goals of the European Health Data Space (EHDS), ensuring that health data can be securely and ethically used for research, policymaking, and healthcare innovation.

About the TEHDAS2 Project

The TEHDAS2 (Towards the European Health Data Space) joint action is a large-scale EU-funded project, involving 29 countries and coordinated by the Finnish Innovation Fund Sitra. Building on the work of previous projects like TEHDAS, the goal of TEHDAS2 is to support the European Commission in establishing the European Health Data Space (EHDS). TEHDAS2’s primary aim is to create clear guidelines and technical specifications that will enable the safe, ethical, and cross-border secondary use of health data under the EHDS framework. By harmonising data access procedures, security standards, and citizens' rights protections, TEHDAS2 strives to facilitate the efficient use of health data for research, innovation, and regulation, which can ultimately lead to better healthcare outcomes across Europe.

Details of the Public Consultation

The TEHDAS2 public consultation will take place from 30 September to 30 November 2025. During this period, stakeholders will be invited to review and provide feedback on 11 draft guidelines and technical specifications, which are key to the implementation of the EHDS. These guidelines focus on critical areas such as data access procedures, secure processing environments, data minimisation, and citizens’ rights in the context of health data usage.

The consultation process presents a unique opportunity for stakeholders—ranging from citizens and healthcare professionals to regulators and policymakers—to actively participate in shaping the future of health data use. The documents cover various topics, including penalties, data security, and the rights of individuals to opt-in or opt-out of data sharing. The feedback gathered will ensure that the guidelines address the real-world needs of stakeholders and support the smooth implementation of the EHDS.

Following the consultation period, the feedback will be analysed and incorporated into the final documents, which will then go through an internal approval process before being published.
