MediZyra: A Cyber-Resilient, Offline-First Hospital Care Coordination Platform with Role-Based Triage Workflows

This research demonstrates the viability of a cyber-resilient, offline-first hospital care coordination platform as a practical response to the growing threat of ransomware and connectivity-disrupting cyberattacks in healthcare environments. MediZyra Healthcare Solutions achieves full three-role workflow operation -- from patient care request through admin triage to doctor-led clinical closure -- without dependency on cloud infrastructure or internet connectivity.   By maintaining all operational components (React 19 frontend, Express.js API, and MongoDB persistence) within a single local machine environment, the system dramatically reduces the attack surface available to ransomware and other cyber threats that routinely disable internet-connected hospital systems. The role- hierarchy enforcement, status-transition rules, and local MongoDB persistence together demonstrate that continuity-focused design principles can be practically realised in an academic prototype context.   MediZyra serves both as a functional hospital coordination prototype and as a concrete demonstration of offline- first resilience thinking relevant to real-world healthcare cybersecurity planning. The platform's modular architecture further positions it as a viable foundation for extension into production-grade hospital management systems
