Drug Inventory Supply chain Management Using Blockchain

Abstract: The Drug Inventory & Supply Chain Management System using Blockchain technology is a novel solution developed to address the serious issues affecting the pharmaceutical supply chain such as counterfeit drugs, lack of transparency, inefficient tracking and data tampering. This can lead to significant adverse effects in the case of patient safety and violations of regulatory requirements. The proposed system utilizesblockchain as a solution to facilitate secure, immutable and decentralized data sharing across all involved parties–rangingfromdrug manufacturersand distributor stopharmaciesandhealthcareproviders. In the center of the solution is a blockchain-based ledger which securely stores all transactions and movements of drug inventory. Each drug batch is assigned an unique digital identity using QR codes or RFID tags and their entire journey from production to consumption is documented in real time on the blockchain. This end-to-end traceability provides both verification of accuracy in the supply chain and complete auditability of supply chain for regulators and healthcare organizations. Smart contracts are used to automatically execute some facets of the supply chain such as drug delivery, inventoryreplenishment,andpaymentsettlement.Smartcontractsenforcecertainconditions(i.e. confirmdeliveryofadrugormaintainaspecifiedtemperature)tocompleteagivenprocess.This improves the speed to market of the supply chain, reduces human intervention, and promotes more trust among supply chain partners through enforceable code. Also, with the introduction of IoT devices, the system can measure other environmental factors like temperature and humidity during storage and transportation, thereby ensuring the safe handling of highly sensitive medications and immediately putting in place preventive measures if such deviations occur. In addition, with the help of data analytics, the system will be able to predict the demand patterns, helpingusers measure their inventory levels to ensure they remain at their desired level while reducing waste. Blockchain combines with advanced supply chain management practices and technology to provide significant efficiency and security gains while improving patient safety and public health outcome. Blockchain represents an unprecedented development in pharmaceutical logistics – a new transparent, tamper-proof and efficient tool to manage drug inventory in today’s increasingly complex and global healthcare environment
