Medical Report Management & Distribution System On Block Chain

Generally, the Hospital operations involve a lot of medical reports which are an integral part of operations. Hospitals these days have increased their business by integrating pathology and other test labs within the hospital for efficient and fast reports along with increased business. Hospital operations include a variety of processes from patient admission, management, to hospital expense management. This coupled with added services like pathology and pharmacy management increases operational complexity and also makes it difficult to track. So, to overcome this problem, we use a block chain technology to keep track of every single transaction with a 100% authenticity through the hyper ledger concept. All transactions are secured by an encryption and stored as blocks to authenticate within a network of computers rather than a centralized server. Moreover we use hyper ledger concept to associate and store all the associated medical documents associated with each transaction with date stamp. This allows verifying the authenticity of each report which will be detected if modified by any individual.
