Helathcare Management System

Healthcare services are increasingly dependent on digital systems for storing and managing patient information. Traditional centralized hospital databases are vulnerable to unauthorized access, tampering, and cyberattacks, which compromise privacy and patient trust. This paper presents a blockchain-enabled hospital management system that ensures secure, transparent, and tamper-proof storage of patient records, appointments, billing, and medical histories. By integrating blockchain technology, the system enhances data security, accountability, and interoperability across hospitals, pharmacies, insurance providers, and laboratories. Smart contracts automate key operations such as appointment confirmations, billing, and insurance claims, thereby reducing paperwork and administrative delays. The proposed solution empowers patients with greater control over their medical data, while also improving coordination among healthcare stakeholders. The study demonstrates that blockchain-based hospital management systems can provide scalable, efficient, and patient-centric healthcare services.
