Innovative Blockchain-Enhanced Clinical Trial Management and Stakeholders Interoperability

Using blockchain technology to oversee clinical trials has the potential to drive innovation and significantly improve traditional data management practices. This paper proposes a blockchain-oriented approach to tackle the prevailing issues within clinical trial management frameworks and promote interoperability among clinical trial stakeholders. Our proposed blockchain system is designed to be patient-centric and cost-effective while enhancing data sharing and real-time collaboration in clinical trials. This model aims to address data security, trust, and traceability issues. The smart contract was developed using Remix IDE, we included in the smart contract a mechanism that monitors patient participation during the trial. This function will automatically restrict access to any patient that defaults to the blockchain network. The smart contract we designed registers all participants in clinical trials, including patients, with their consent forms and allows patients to report any adverse effects. All transactions within our smart contract are timestamped to ensure transaction Ordering and mitigate manipulation vulnerabilities. The contract is programmed to grant certain members special authority, as outlined in the system model section. Additionally, our model can be deployed on any Ethereum-based blockchain network, private or public.
