A systematic study on integrating blockchain in healthcare for electronic health record management and tacking medical supplies

In the current landscape of swiftly evolving technology, security remains a paramount concern. Motivated by the challenges presented during pandemics such as COVID-19, this article aims to enhance healthcare transparency and expedite treatment processes. The existing centralised medical data management system scatters patient records across disparate hospitals and pharmacies, prompting the necessity for a patient-centric data repository. The integration of blockchain emerges as a viable solution, giving patients control over their information and facilitating seamless sharing with relevant institutions—be it hospitals, pharmacies, or insurance firms. This article outlines a strategic framework for securing medical data based on comprehensive literature review and proposes measures derived from previous studies. Furthermore, the study explores blockchain's application in tracing medicinal supplies, crucial for detecting counterfeit medications within the supply chain. Detailed elucidation of IBM Research's proposed model highlights the potential of blockchain in this domain. Additionally, an extensive comparative analysis of existing models underscores their strengths and limitations in these healthcare applications. Challenges persist in deploying blockchain in developing countries, primarily due to resource limitations, signalling the need for tailored solutions conducive to such environments. This study serves as an exploration, emphasising the need for continued research and innovation in harnessing blockchain's potential for healthcare transformation.
