Blockchain can help to address the issue of lacking a way to manage health data efficiently. The adoption of blockchain technology can simplify medical data management. For example, a patient's medical history, diagnostic information, and test results are kept at their respective doctors' offices. Sharing medical information among doctors, for instance a patient's family physician and specialists, is time-consuming and difficult.  This could lead to a delay in diagnosis or generatre redundant medical tests. The blockchain can make data sharing easier, while the confidential data is well protected. The detailed medical records can then be aggregated. The aggregated information can be made available to medical researchers, government agencies, and pharmaceutical or insurance companies. With simplification and worldwide access, health data sharing helps promote cooperation among researchers and pharmaceutical companies in the development of new treatments and drugs. Based on real health data, government agencies can make improved health policies. Medical insurance firms can utilize data to calculate the premiums for plans and reduce the cost of collecting the required data. The same goes for decentralizing the results of clinical trials. In summary, blockchain can revolutionize how health data is stored, managed, and shared. It will profoundly impact the development of the health industry as a whole.
