“…The prototype can be altered to solve problems related to patient records and clinical decision support systems. (31,32) More work will follow to develop a Hyperledger Fabric network based on the conceptual model. Overall, conventional risk management in healthcare construction has a huge room for improvement and blockchain-based implementation seems highly applicable.…”

Hospitals provide diverse tasks essential for the delivery of patient care and are comprised of many functional units. This makes healthcare construction projects highly complex among other types of building projects due to the specific regulations, multiple functions it must provide, complicated mechanical and electrical systems, and so on. This complexity embodies potential risk events during its construction, which not only influences the completion of the project but can impact the patients’ safety and health conditions even after the project is finished. To prevent such outcomes, risk management is a crucial process that can identify, evaluate, and properly mitigate risks along the project lifecycle. A key aspect of risk management is that it requires the interaction and contribution from multiple stakeholders of the project. Various frameworks and tools that enable collaborative management of risks among multiple stakeholders have been developed in the past. However, the developed frameworks are not suitable in the sense that it does not protect the confidentiality of individual inputs from the stakeholders. Moreover, these frameworks are centralized systems, which can bring issues related to the security and transparency of the information that is being stored. Blockchain technology is an emergent distributed ledger technology (DLT) that can provide solutions to the listed problems found in centralized systems. It is a novel system that records information on a decentralized, distributed ledger, where transactions are constantly duplicated and updated. This study explores the applicability of blockchain technology for healthcare risk management. The key functional elements of blockchain that can resolve the challenges faced by prior risk management frameworks have been identified and discussed. Based on the discussions, a conceptual information management model for managing healthcare project risks on a blockchain has been conceived. The development of the initial prototype has been explained. The research illustrates the process, benefits, and limitations of adopting blockchain technology for collaborative risk management in healthcare projects.

“…3) Semantic, in which there are syntax and semantic data exchange and interpretation. Within blockchain-based healthcare applications, [24] proposes an interoperable OpenPharma blockchain solution, which uses public Ethereum blockchain as an interoperability layer between existing vendor solutions. The blockchain is used to store encrypted patient information URLs and share them with doctors who obtain the patient's encrypted authentication ID.…”

Blockchain technology has the potential to revolutionize industries by offering decentralized, transparent, data provenance, auditable, reliable, and trustworthy features. However, cross-chain interoperability is one of the crucial challenges preventing widespread adoption of blockchain applications. Cross-chain interoperability represents the ability for one blockchain network to interact and share data with another blockchain network. Contemporary cross-chain interoperability solutions are centralized and require re-engineering of the core blockchain stack to enable inter-communication and data sharing among heterogeneous blockchain networks. In this paper, we propose an application-based cross-chain interoperability solution named appXchain which allows blockchain networks of any architecture type and industrial focus to inter-communicate, share data, and make requests. Our solution utilizes the decentralized applications as a distributed translation layer that is capable of communicating and understanding multiple blockchain networks, thereby delegating requests and parameters among them. The architecture uses incentivized verifier nodes that maintain the integrity of shared data facilitating them to be readable by the entities of their network. We define and describe the roles and requirements of major entities of inter-operating blockchain networks in the context of healthcare. We present a detailed explanation of the sequence of interactions needed to share an Electronic Medical Record (EMR) document from one blockchain network to another along with the required algorithms. We implement the appXchain solution with Ethereum-based smart contracts for two hospitals and also present its cost and security analysis. We have made our smart contracts code and testing scripts publicly available.

Decentralized digital manufacturing can contribute in advancing automation to overcome the limitations posed by most of today's manufacturing systems due to the Coronavirus 2019 (COVID-19) pandemic. However, certain challenges, such as attestation and certification of the product, tracing the product throughout the entire process, and ensuring the protection of intellectual property (IP) rights, are hindering its widespread adoption. In this paper, we propose a blockchain-based solution for decentralized digital manufacturing of medical devices and supplies during the Covid-19 pandemic. We develop Ethereum smart contracts to govern and track the different participants' transactions throughout the process in a manner that is decentralized, transparent, traceable and trackable, auditable, trustworthy, and secure. We incorporate the decentralized storage of the InterPlanetary file system (IPFS) into the Ethereum blockchain to store and fetch manufacturing records, Internet of things (IoT)-based devices records, and additional product and digital manufacturing process details. We present the system architecture and algorithms along with their full implementation details. Furthermore, we present cost and security analyses to show that the proposed solution is cost-efficient and resilient against well-known vulnerabilities and security attacks. We make our smart contracts code publicly available on GitHub.
