The significance of medical test records in diagnosing and treating illnesses cannot be overstated. These records serve as the foundation upon which medical professionals craft precise treatment strategies tailored to a patient's unique health condition and ailment. However, in several developing nations, such as Vietnam, a concerning trend persists: medical test records predominantly exist in vulnerable paper format, entrusted to patients for safekeeping. When patients transition between healthcare facilities, the responsibility of carrying these paper-based medical histories rests with them, introducing a significant risk factor due to the inherent fragility of paper documents, which can be easily damaged by fire or water. The loss of these crucial records can lead to severe disruptions in the diagnostic and therapeutic journey of patients, potentially compromising their well-being. Despite the emergence of various alternatives to address this vulnerability, Vietnam faces multifaceted challenges. These challenges encompass low technological literacy among patients and substantial infrastructural limitations. In response to these pressing issues, this study endeavors to harness the transformative potential of blockchain technology, smart contracts, and Non-Fungible Tokens (NFTs) to effectively mitigate the drawbacks associated with paper-based medical test records. Our comprehensive approach includes meticulous cataloging of current hospital practices, the introduction of a purpose-built blueprint for decentralized record sharing, the proposal of an innovative NFT-backed authentication model, the development of a practical proof-of-concept, and comprehensive platform testing. Through these efforts, we aim to revolutionize the management of medical test records in Vietnam, enhancing accessibility, security, and reliability for both patients and healthcare providers.
