In countries where patients can access the electronic health record (EHR), they enhance its accuracy by requesting corrections of EHR errors (EHRrors). This study compared national legislative frameworks in Sweden, the UK, and Germany governing patient rights to changing, adding, and deleting EHR information against General Data Protection Regulation (GDPR) and the forthcoming European Health Data Space (EHDS). We found that while national laws largely mirrored GDPR, they offered different additional mechanisms to EHRror management. Importantly, the EHDS positions the rectification process in the digital health service, opening the possibility for in-EHR patient input, which may further patients’ contribution to maintaining accurate clinical documentation and enhance patient agency.
