Abstract: This study seeks to enhance the security, efficiency, and usability of Thailand’s health information system through the integration of blockchain technology and a user-friendly web application. Blockchain’s inherent strengths in secure data stor-age and sharing make it particularly well-suited for addressing the critical challenges of healthcare data management. Currently, Thai citizens face significant barriers when seeking medical treatment across multiple hospitals, as they must manually request and transfer both their Electronic Medical Records (EMRs) and paper-based medical records. This fragmented system creates delays and inefficiencies, as each hospital operates its own isolated data silo. To overcome these challenges, this study proposes a solution utilising a private blockchain to securely store and manage patient medical histories and prescriptions. This approach ensures data integrity while implementing robust authorisation mechanisms to restrict access to sensitive information exclusively to verified individuals. The system’s security is further strengthened by blockchain’s encryption features and the use of smart contracts. A well-designed web application serves as the interface between the secure blockchain database and end-users, offering a seamless experience for both healthcare providers and patients. In addition, User Experience (UX) testing was conducted with healthcare providers to assess the system’s usability and functionality. The results highlight the system’s user-friendly interface, confirming its potential for widespread adoption. By fostering efficient, secure, and patient-centric health information exchange, this study has the potential to significantly enhance healthcare delivery and outcomes in Thailand.
