The traditional healthcare systems operate with manual processes and paper-based record-keeping, involving patient registration, medical record creation, appointment scheduling, billing, and communication through traditional methods. These systems face challenges such as data silos, security vulnerabilities, and interoperability issues. Cyber threats, data breaches, and identity theft pose significant risks to these systems. Moreover, maintenance challenges, security concerns, and inefficiencies in information exchange highlight the need for improvements. The introduction of Electronic Health Records (EHR) represents a transformative shift, but it comes with its challenges. Blockchain technology emerges as a solution, offering decentralized security, smart contracts, data interoperability, and immutability. Blockchain's decentralized architecture mitigates security risks, while smart contracts automate access controls. Standardized data formats and a decentralized network enhance data exchange, and immutability ensures data integrity. The proposed approach involves Ethereum for decentralized applications, IPFS for distributed file storage, and On-chain transactions for blockchain updates. The smart contract acts as an authenticated agreement between parties. This comprehensive overview provides a nuanced understanding of traditional healthcare challenges, blockchain solutions, and the evolving landscape of EHR management.
