A qualitative study on expectations of health data experts from 23 countries
30 November 2025
As the formal adoption of the European Health Data Space (EHDS) draws nearer, questions surrounding the implementation of rules for the secondary use of health data abound.
This study aims to explore the expectations of health data experts regarding the implementation of the EHDS.
To gain insights, we conducted semi-structured interviews with participants from 23 European countries. Data were analysed using inductive content analysis to identify key themes.
Our findings reveal that the EHDS addresses some of the existing challenges for secondary health data use by setting clear rules for health data reuse and introducing new opportunities, such as enhanced competitiveness and cross-border data sharing. However, the implementation of the EHDS also brings about new challenges, including uneven interpretation across Member States, interaction with existing regulations, increased fees for accessing health data and heightened risks of data misrepresentation. These issues highlight the complexity of aligning diverse healthcare systems under a unified framework.
Significant investments are necessary to address the heterogeneity of health data and digital health systems across the Union. Additionally, incentives are essential to ensure the active engagement of all stakeholders, especially where systems for health data sharing and reuse are already in place.
