The EC has recognised the benefits of data generated by wellbeing applications (with both devices and mobile apps) in the context of healthcare. Such data will be able to be used for primary data use - users of wellbeing apps will need to be informed if the apps can be linked to EHR systems, but also for secondary data use - as we discuss below.
Secondary use of electronic health data
Recent years have brought significant technological developments in the medical field. An example is the development of a machine learning algorithm to predict a hypotension minutes before it occurs with a certain degree of probability based on high-fidelity arterial pressure waveform analysis[1] . However, to ensure further technological development, it is essential to enable the use of health data for research and development, including the teaching of new artificial intelligence systems to support doctors in their work.
The EHDS Regulation identifies categories of electronic health data that can be processed for secondary use. Such data may include, in particular, data from the healthcare system (e.g. disease registries, electronic health records), but also health impact data (e.g. consumption of various substances, minimum income, environmental factors) and data generated by individuals through the use of e-health devices or applications, including wellness applications.
Both public and private entities, excluding micro-enterprises, will be obliged to make data available for secondary use. The exclusion of smaller entities from such obligations and supporting the development of smaller market players by allowing them greater access to data is, in fact, a recurring feature of the legal acts of the European Digital Decade[2] .
When applying for access to electronic health data for secondary use, a valid legal basis must be indicated. Access to the data will be granted if the intended purpose of the processing carried out by the applicant is compatible with the purposes enumerated in the EHDS Regulation (among others, research in the health or health care sector, development and innovation activities in the health area, public statistics on health sectors at national, multinational and EU level).
The EHDS Regulation also includes a catalogue of purposes that exclude the possibility of accessing electronic health data - including, among others, for the purpose of making decisions in relation to an individual to exclude him or her from an insurance contract or to change his or her contribution and insurance premiums, or for the development of products or services that may be harmful to individuals and the community at large (including, in particular, alcoholic beverages, tobacco products and illicit drugs).
Member States will be obliged to designate one or more data access body, which will be the entity competent to review and decide on a request for access. Other tasks of the data access body include the obligation to support the development of artificial intelligence systems, to train, test and validate artificial intelligence systems, and to develop harmonised standards and guidelines on the basis of the Artificial Intelligence Act (on which work is also currently underway).
Data access body will monitor and supervise compliance by users and data holders with the requirements set out in the EHDS Regulation. In situations where the data access body observes non-compliance, after a prior investigation procedure and the opinion of the monitored entity, the data access body will be able to revoke the access authorisation and suspend or completely withdraw access to electronic health data for a period not exceeding 5 years.
Cross-border infrastructure for the secondary use of data - DataHealth@EU
For the secondary use of electronic health data, a new common infrastructure, HealthData@EU, will be established. Its aim is to facilitate the secondary use of data. As with primary use, participation in the infrastructure for secondary use of data will be mandatory.
The entity responsible for making electronic health data available for secondary use will be the national contact point for secondary use of electronic health data, to be established in each Member State.
Coordination and management at European level
In order to secure a coherent application and interpretation of the rules (in particular through cooperation and exchange of information between Member States), a European Health Data Space Board will be established.
