Challenges of Blockchain Applications in Digital Health: A Systematic Review

Abstract: Digital health, an emerging field integrating digital technologies into healthcare, is rapidly evolving and holds the potential to transform medical practices. Blockchain technology has garnered significant attention as a potential solution to various issues within digital health, including data security, automation, interoperability, and patient data ownership. However, despite the numerous advantages, blockchain faces several challenges and unknowns that must be addressed. This systematic literature review aims to explore the challenges of blockchain applications in digital health and provide best practices to overcome current and future roadblocks. Key issues identified include regulatory compliance, energy consumption, network effects, data standards, and the accessibility of the technology to stakeholders. To ensure the successful integration of blockchain within digital health, it is crucial to collaborate with healthcare stakeholders, pursue continued research and innovation, and engage in open discussions about the technology's limitations and potential.
