During recent decades, providing patients with access to their electronic health records (EHRs) has advanced in healthcare. In the European Union (EU), the General Data Protection Regulation provides individuals with the right to check their data in registries such as EHRs. A proposal for a European Health Data Space has been launched, which will further strengthen patients’ right to have online access to their EHRs throughout Europe. Against these policy changes, scant attention has been paid to the ethical question about whether adolescents and parents should access the adolescent’s EHR, and if so, under what conditions.
