Material/Methods: Staff members (radiation oncologists, radiotherapy technologists, and information technologists) at radiation oncology departments in Poland and Serbia were surveyed to assess practices related to data protection and exchange. EU and national regulations were reviewed to identify key issues related to the processing of patient data through the local hospital information system (LHIS) and the national HIS (NHIS). The practices at these two departments were observed from June 1 to October 31, 2024 to assess compliance with data security protocols. Results: In both countries, patients' personal and medical data are processed electronically in accordance with national regulations. In Poland, data confidentiality is ensured by both national and EU law, including the General Data Protection Regulation (GDPR). In Serbia, data confidentiality is regulated only by national law. While some laws in Serbia have been adapted to meet EU regulations, the laws applicable to patient data protection have not been modified. Under national regulations in both countries, patient data must be transferred from the LHIS to the NHIS. In Poland, the integration is bi-directional. In Serbia, data is only transferred unidirectionally (LHIS to NHIS). In both cases, the integration is based on HL7 (text) and DICOM (images) standards for the electronic exchange of healthcare information. In both countries, the LHIS includes hospital, radiology, laboratory, and pharmacy data. In Serbia, only raw textual data (metadata) are transferred to the NHIS: patient name and contact details; reason for referral; hospital treatment; and raw laboratory/radiotherapy data. Poland transfers these same raw data as well as data on prescriptions; visit information sheet; histopathological results; and hospital admission (agreed or refused). Medical documents signed electronically by authorised persons are also transferred. No diagnostic images or patient consent forms are transmitted in either country.
