A Blockchain-Based approach in Healthcare Supply Chain using Smart Contracts and Decentralized Storage Systems

ABSTRACT

Despite substantial advancements in healthcare systems and management, little progress has been achieved in addressing supply chain constraints such as, inefficient purchasing, ordering, predicting, and administration procedures. Healthcare authorities needs to effectively manage the healthcare supply chain processes not just during pandemics like COVID-19, but also in their everyday operations to guarantee best possible services. Product recalls, product supply shortage monitoring, expiry, and counterfeiting are some of the critical healthcare supply chain operations which must be ensured. Our suggested solution combines blockchain technology and distributed storage to increase transparency, improve stakeholder communication, and shorten product procurement timelines while eliminating crucial disparities and faults. We present a generic framework for the healthcare supply chain, equipped with comprehensive algorithms showing various stakeholder interactions. Our system uses the Ethereum network to link all parties, including the healthcare authority, manufacturer, wholesaler, retailer, and healthcare provider. Remix IDE platform was used to develop and test the smart contract codes. As decentralized storage, we have used the combination of InterPlanetary File System (IPFS) and Hyperledger Fabric. We have also examined a variety of security issues, provided a cost analysis of the various transactions proposed in our solution while making comparison with similar blockchain-based solutions. © 2022 Owner/Author.
