Inefficiencies in blood product management systems, including segmented operations, lack of detailed data sharing, and limited real-time visibility, can often result in significant annual losses in product wastage and postponed medical procedures. Left unaddressed, the negative impact on patient health and healthcare systems can be substantial as blood donations continue to decline. This paper proposes the Cooperative Blood Inventory Ledger (CoBIL), a blockchain and smart-contract enabled system designed to mitigate some of these inefficiencies by increasing cooperation among all echelons of the blood supply chain, without sacrificing entity privacy and competition. The proposed framework facilitates collaborative decision-making among all stakeholders to distribute blood products across healthcare networks and reduce system costs. It also facilitates product redistribution among hospitals and other transfusion points to reduce losses due to expired product or canceled medical procedures due to product shortages. A role-based smart contract is included in the framework to define stakeholder access and manage data exchange. To analyze the feasibility of the proposed framework, we implement a proof of concept on a local machine using Hyperledger fabric’s test network and employ it to simulate transactions required for the inventory operations of a regional blood supply chain.

合作血液库存分类帐(CoBIL):用于改善血液产品管理的分散决策框架

血液产品管理系统效率低下,包括分段操作、缺乏详细的数据共享和有限的实时可见性,通常会导致产品浪费和医疗程序推迟的年度重大损失。如果不加以解决,随着献血量的持续下降,对患者健康和医疗保健系统的负面影响可能是巨大的。本文提出了合作血液库存分类账 (CoBIL),这是一个支持区块链和智能合约的系统,旨在通过在不牺牲实体隐私和竞争的情况下增加血液供应链所有层级之间的合作来缓解其中的一些低效率。拟议的框架促进了所有利益相关者之间的协作决策,以在医疗保健网络中分配血液产品并降低系统成本。它还有助于在医院和其他输血点之间重新分配产品,以减少因产品过期或因产品短缺而取消医疗程序造成的损失。框架中包含一个基于角色的智能合约,用于定义利益相关者访问和管理数据交换。为了分析所提出框架的可行性,我们使用 Hyperledger Fabric 的测试网络在本地机器上实现了概念验证,并使用它来模拟区域血液供应链的库存操作所需的交易。
