European Health Data Space, Use of Data and Data Subjects' Control over Their Own Health Data: Can an Opt-Out Restore the Balance?

The creation of the European Health Data Space is a milestone. It establishes something new and makes it possible to have faster and more efficient health treatment, but also to untap the potential of unused data for policy-making and development of new technologies. However, for the EHDs to be functional, it is imperative that a balance it struck between the aim of having useful data to achieve important public objectives on one side and the goal of enabling patients to have control over their health data. The original Draft Report of the European Parliament came closest to achieving these objectives and should have represented the blueprint for the final compromise. Having a harmonised opt-out for secondary use is crucial for striking the right balance between the mentioned objectives. The end result is far from perfect regarding primary use, but represents a good balance in the area of secondary use concerning the opt-out.
