N2  - This research investigates how blockchain technology can be applied to design a distributed  Electronic Health Record (EHR) ecosystem tailored to the context of Vietnamese public  hospitals. Amid rising demands for digital transformation in Vietnam's healthcare system,  traditional EHR systems have struggled with fragmentation, limited interoperability, weak  patient control, and data privacy concerns. To address these issues, this study adopts an action  research methodology and develops two in-depth case studies at Hospital-A in Hanoi and  Hospital-B in Ho Chi Minh City, two of Vietnam{u2019}s leading national referral hospitals.  The study presents a comprehensive analysis across seven dimensions: institutional  background, organizational governance, clinical services, academic and research role,  digitalization strategies, blockchain-based EHR design, and summary insights. Both hospitals  have implemented pilot blockchain systems using Hyperledger Fabric, integrating smart  contracts, IPFS storage, and VNeID-based patient authentication. The research highlights key  findings regarding system interoperability, trust enhancement, and the role of smart contracts  in access control and consent management.  Through qualitative data from interviews, focus groups, and technical implementation reports,  the study identifies critical enablers and barriers to blockchain adoption in the Vietnamese  healthcare environment. These include technical capacity, hospital leadership, regulatory  readiness, and inter-hospital collaboration. By evaluating the technical architecture,  performance, and implementation process in two contrasting urban settings, the research offers  a framework for scalable, secure, and patient-centered digital health transformation. It  concludes with policy recommendations, a roadmap for national EHR interoperability, and  implications for blockchain adoption in other low- and middle-income healthcare systems.
