Blockchain Technology for Health Care

The platform Blockchain permits a transparent, open environment without any centralized authority. Exchanges are secure and reliable at the same time because of the use of encryption principles. Due to the popularity of cryptocurrencies, blockchain technology has been becoming extremely trendy and penetrated in different areas in recent years. One area where blockchain technology is enormous is healthcare because of the need to approach healthcare systems more patient-centered, to connect various systems and improve the accuracy of health records (EHRs). In this systemic review, an analysis is carried out of state-of-the-art healthcare blockchain research. The objective is to unveil the technology’s possible applications and to highlight the challenges and possible directions in blockchain health research. Blockchain technology is among the most significant observations and creative developments in today’s professionals. Technology of Blockchain moves towards continuous revolution and transformation. It is a chain of blocks that encompasses relevant data and continues to maintain confidence between people regardless of how far they are. The rise in blockchain technology in the last couple of years has forced researchers and professionals to look at new ways to implement blockchain technology with a wide range of areas. The substantial rise in blockchain technology has given many software innovations, including healthcare. This chapter offers an integrated analysis of emerging healthcare blockchain-based technology and information software applications. In this, we draw attention to and explain in certain details the open issues in this rapidly growing field. In revolutionizing the medical industry, we also show the potential of blockchain technology. Blockchain is a system that creates a secure, immutable, distributed transaction database. Initially, Blockchains were established to provide a distributed financial transaction ledger that did not depend on the central bank, credit company or other bank. However, the technological advance was extended to transactions in law, the clinical record keeping, insurance billing and intelligent contracts. One important way for healthcare professionals to blockchain technology is to revolutionize clinical coordination. This increased interaction can contribute to better access to medical records, imaging archives, prescription database systems. Background information, followed by a description of exact methodology used in this chapter, is discussed first, given that patient medical history is a key cornerstone of good medicine. The blockchain technology has an opportunity to dramatically improve medical care. Next a bibliometric survey, an analysis of the data and their characteristics and the results of the literature quality evaluation is analyzed. Finally, the findings of the study are being addressed. The results show that blockchain technology in healthcare is growing and used mostly for data sharing, health records management and control of access. There are very rare other scenarios. In each of these works, modern structural designs are described in the form of frames, frameworks or templates. Findings also demonstrate that in most of the analyzed articles, technical information on the used blockchain components are not presented and that most analysis does not provide prototype application or implementation details. Often no information about blockchain components is provided except for a prototype implementation.
