Enhancing healthcare using blockchain technology: blood donation supply chain

Abstract

Blood banking is a complicated business: it’s a multibillion-dollar industry where the majority of the product is donated and then sold by nonprofit organizations. Slipping safety standards, poor employee training, deteriorating equipment and a desire for profits, according to government officials, have put the industry in jeopardy. Blood banks compete fiercely for contracts to supply domestic hospitals. Blood can also be refined into a variety of higher-priced products, similar to oil, with market values fluctuating widely based on global supply and demand.(new your times) The main goal of choosing Blockchain technology is to improve the traceability in supply chain processes as well as tracing and tracking drugs during manufacturing and shipment. They also trace and track drugs during manufacturing and shipment. In this study, we deployed a blockchain-based solution for the blood donation supply chain. Because current systems are vulnerable to contamination and falsification, it is clear that the blockchain can reduce the risk of contaminated blood donation. Moreover it can help to verify the source of blood and make sure it comes from a trusted source. The proposed solution will decrease ethical risk by creating a decentralized donor registry. By using this system, donors can control their data and donation process. In our system, we used Blockchain, which enabled us to introduce transparency and traceability along with additional layer of security in the Blood donation supply chain. By applying the smart contract feature in Ethereum Blockchain we were able to design an advanced decentralized access management for the entities in our proposed system. For evaluating our proposed solution, we assessed our system from different perspectives and by optimizing our design, we observed that gas consumption was decreased significantly in comparison to the similar supply chain smart contracts. Our system will help to create an innovative blood donation that would help to increase the number of donors in the future.
