Blockchain technology has rapidly evolved into a key area of interest across various sectors, including healthcare. Researchers and policymakers alike are exploring its potential to enhance data security, improve interoperability and optimize operational efficiency in healthcare systems.

Mettler [1] was among the early scholars to highlight blockchain’s flexibility and its disruptive potential in healthcare, particularly in public health data management, patient-centric research and combating pharmaceutical counterfeiting. This foundational work set the stage for subsequent investigations into blockchain’s diverse applications in the healthcare domain. Gordon [2], explored five key mechanisms through which blockchain facilitates a shift toward patient-driven interoperability-digital access rules, data aggregation, liquidity, identity and immutability. He also acknowledged several challenges, including scalability, privacy and incentives for stakeholder participation, which remain critical barriers to adoption.

Building upon this foundation, Agbo et al. [3] conducted a comprehensive systematic mapping study using PRISMA guidelines to categorize existing literature on blockchain in healthcare. Their review uncovered a growing interest in blockchain-enabled solutions but also revealed inconsistencies in methodology and a lack of standardization across studies. Khezr et al. [4] and Ben Fekih and Lahami [5] contributed broad surveys detailing state-of-the-art applications, including Electronic Health Record (EHR) sharing, remote patient monitoring and supply chain transparency. These studies emphasized blockchain’s capacity to address long-standing issues in healthcare information systems. Jabbar et al. [6] focused on the evolving role of blockchain in EHR systems. Their work underlined the importance of data integrity and interoperability across healthcare stakeholders, reinforcing blockchain’s potential as a unifying infrastructure for health data exchange. Abu-Elezz et al. [7] categorized blockchain benefits into two major groups: patient-centric advantages (e.g., personalized care, secure access, real-time monitoring) and organizational benefits (e.g., health information exchange, pharmaceutical traceability, clinical trials). Their findings stress the importance of a balanced perspective when evaluating blockchain’s impact. Haleem et al. [8] and [9] presented a practical overview of blockchain applications, particularly for error detection in healthcare processes and data-sharing across institutions.
