The utilization of blockchain in supply chain management is very effective in recent years. By using blockchain in SCM transactions has efficiently traceable and auditable. This survey aims at providing an overview of various existing research papers that discuss the role, applications, and probable of blockchain in revolutionizing the medical supply chain. The studies surveyed collectively underscore the dire need for enhanced transparency within the ecosystem of healthcare. Blockchain provides real time tracking of medicine goods in secure manner in SCM. One of the themes that keeps cropping up in the research is how blockchain will be able to help block counterfeit drugs and improve traceability of pharmaceuticals from production to delivery to the very end-user. Some studies also look more closely at smart contracts in automatic processes like the making of a payment, procurement, and even compliance management. Thus, with blockchain, business operations are also being improved. Also, blockchain studies have looked more intently at data integrity and safe ways in which information among stakeholders-manufacturers, distributors, healthcare workers, and even regulators-can share or be shared to them. However, this surveyed research also recognizes the scalability issues, regulatory hurdles, and high cost of initial investment in implementing blockchain. This body of work has thus demonstrated that though blockchain holds great potential for transforming the medical supply chain, more research and stakeholder collaboration is required to achieve broad-based adoption and realization of benefits.
