This paper examines the concept of Hadoop and blockchain in developing intelligent medical systems. Health knowledge systems are growing in popularity across the world. As digital technology develops rapidly, many local medical organizations are expanding the introduction of information-based, comprehensive systems. Such programs also increased the quality of operation and central efficiency of the hospital [1]. IT not only increases the quality of the clinical practice, but it also encourages physicians to have even more time to treat patients, to increase patient comfort and confidence, and to develop an invisible empirical glimpse of medical institutions [1]. This is a really interesting moment for healthcare and IT (IT). Thanks to advances in genetic testing and the development of precise medication, healthcare has a groundbreaking strategy for preventive care that integrates the genetic structure, lifestyle, and environmental conditions of the particular patient. At the same time, IT progress has created vast health information databases, provided resources for tracking health data, and involved people in their health. Combining these advances in healthcare will encourage transformative changes in health IT. Blockchain is a successful game changer for advancement in medical data storage because it is a collaborative reporting technology with multi-party maintenance and data backup security [1,2]. This paper creates the medical records center on the large data network Hadoop and securely stores and analyzes the initial dispersed data via the sophisticated processing module and the autonomous data acquisition framework. The customized hospital information system for chronic conditions like stroke utilizes the benefits of the Hadoop Big Data framework to provide patients with personalized health care systems and to promote patient management by medical professionals.
