Abstract: This paper presents an innovative adaptation of the bibliographic MARC21 (MAchine-Readable Cataloging) standard for structuring electronic health records (EHR). Traditionally used in libraries, MARC21 offers a highly flexible numbered field structure that, through systematic adaptation, provides significant advantages for managing complex medical information. The adaptation principles were applied, field mapping for clinical data was performed, and the implementation in a real system using MongoDB was carried out. It was demonstrated that this adaptation supports complex medical modeling while ensuring compatibility, extensibility, and traceability. The results were compared with established standards (HL7, FHIR), and the advantages, limitations, and appropriate use cases were discussed.
