Blockchain technology is increasingly being recognized as a secure and reliable platform for data sharing in various industries such as finance, supply chain management, food industry, energy, internet of things, and healthcare. In this paper, we review existing literature and applications of blockchain technology in the healthcare sector. Additionally, we propose several blockchain-based workflows for improved data management within the healthcare eco system. These workflows include complex medical procedures such as surgery and clinical trials, as well as managing and accessing large amounts of medical data. We have also conducted a feasibility study to estimate the cost of implementing the medical smart contract system for healthcare management .This work aims to facilitate collaboration among stakeholders within the healthcare system to improve services and optimize costs.
