Modernized Health Record Maintenance

This study delves into the transformative potential of blockchain technology in the medical domain. With paramount concern for patient data integrity, the blockchain emerges as a vanguard in safeguarding medical and insurance records from unwarranted third‐party interventions. The system, relying on e‐hash functions, provides robust end‐to‐end encryption, with each e‐hash being a composite of tailored smart contracts for discrete phases of medical record management. Central to this is a distributed ledger, accessible across nodes, ensuring data consistency and transparency. Whenever modifications occur in blocks or nodes, the entire system undergoes concurrent updates, allowing real‐time access for both the patient and their physician. Data retrieval mandates patient consent, emphasizing patient‐centered data sovereignty. A noteworthy parallel exists between the interconnected nature of web servers and the blockchain's structure. As proposed, e‐hash offers a compelling alternative to traditional record‐keeping. Furthermore, the blockchain's peer‐to‐peer architecture holds potential in revolutionizing broader aspects like drug traceability and supply chain management. This robust data repository stands to expedite medical research, offering researchers deeper insights into diseases and paving the way for innovative treatments. An intriguing future proposition emerges with the integration of blockchain with collaborative robots, potentially revolutionizing surgical procedures through automation.
