BLOCK CARE+: A BLOCKCHAIN ENABLED SECURE EHR SYSTEM FOR PREDICTIVE, PERSONALIZED EMERGENCY HEALTHCARE

Abstract

Abstract: This research explores how blockchain technology can revolutionize the management, integrity, and security of Electronic Health Records (EHRs). EHRs encompass essential patient data such as clinical history, diagnoses, medications, and diagnostic reports, which are shared with healthcare providers to enhance medical care. Current EHR systems are predominantly centralized, which introduces risks including single points of failure, data handling inefficiencies, and vulnerabilities in data protection and trustworthiness. Blockchain offers an innovative solution to these challenges by ensuring enhanced security, privacy, confidentiality, and decentralization. This study proposes a structured, flexible, and accessible framework for integrating blockchain into EHR systems. The framework is designed to overcome the shortcomings of existing centralized models by enabling interoperable and connected patient health records. The block chain-based EHR management system highlights the capability to improve upon traditional record-keeping by offering features like robust data protection, interoperability, traceability, decentralization, and process automation using smart contracts. The system has been implemented using Ethereum, and evaluations in terms of cost and performance indicate that the solution is efficient and adaptable to any blockchain platform, be it public or private.
