Introduction
The Electronic health records contain all the essential organizational medical studies applicable to that patient’s treatment under a specific provider, such as demographic characteristics, patient records, issues, prescription drugs, heart rate, medical histories, vaccinations, laboratory information, and radiology findings. The clinician’s process could potentially be streamlined by the EHR, which automates information access. The EHR can also explicitly or implicitly support various care-related operations through several interfaces, such as those for quality control, results reporting, and concrete proof decision support. The subsequent development in healthcare is using electronic health records (EHRs), which can improve communication between patients and medical professionals.

For a very long time, blockchain technology has been a fascinating research topic, and many different businesses have used its advantages. The healthcare industry has much to gain from blockchain technology compared to other industries because of its security, privacy, secrecy, and independence. The Electronic Health Record (EHR) systems do, however, have issues with managing data, integrity, and security. The article explores the potential of blockchain technology to change EHR systems and perhaps provide a fix for these problems. It offers a framework that might be applied to adopting blockchain technology for electronic health records in the healthcare industry. The suggested framework’s two main goals are to use blockchain technology for EHR in the first place and to enable secure electronic record retention by outlining user access guidelines. Through the usage of off-chain data storage, this paradigm also covers the scalability issue that blockchain technology is now experiencing. Due to its advantages, particularly the increase in safety and its expenditure, EHR technologies have been applied in various hospitals and other health systems worldwide. The benefits of possessing a scaled, secure, and integrative blockchain-based alternative are provided to the EHR system by this architecture.

Blockchain could constantly revolutionize how healthcare is provided by putting the patient at the center of the healthcare system and enhancing the safety, confidentiality, and portability of health data. With the help of this system, electronic health records (EHRs) would function more effectively and securely, offering a new paradigm for health information exchange (HIE). Block-chain provides a potential future data-sharing system to facilitate group medical decisions in telehealth and personalized medicine. Block-chain supports a communication and trust mechanism. This article’s primary contribution is a comprehensive literature review of prior research on EHRs and blockchain technology. This analysis examines how a Blockchain structure might be used in healthcare for EHR storage and retrieval administration.
A distributed ledger mechanism known as a blockchain was first connected to Bit-coin. It produces a pre-process, single data chain of material using public key cryptography. The Blockchain concept can be expanded to give a universal foundation for integrating distributed computing capacity, including in the health system, even though it was initially created for preserving a financial ledger. The purpose of this paper is to review and evaluate the research on blockchain technology in healthcare. We aim to identify obstacles and to lingering questions in light of research on potential remedies for healthcare data issues, such as preservation and confidentiality. The writers suggest a classification to make the Blockchain ecosystem easier to grasp and to help future studies.

With the privatization of private medical information in the cloud, the confidentiality of Electronic Health Records (EHRs) is experiencing a significant challenge. It is happening because there is a risk of disclosing health data to unauthorized individuals. EHRs are stored on database technology, which raises the credible threat footprint and necessitates faith in a central agency that is ineffective at defending data from insider threats. In a dispersed context, this study focuses on protecting patient data privacy and security when transferring sensitive data among the same or various institutions and healthcare organizations. This study creates a framework for protecting privacy called Health-chain, built on Block-chain technology and upholds the safety, confidentiality, adaptability, and authenticity of e-health information. By utilizing the intrinsic characteristics of the blockchain, the research aims to build a platform for creating information security against cyber-attacks and increase ecosystems’ sturdiness for sharing health-related information. The results demonstrate the efficacy of the suggested model in terms of information security, improved information privacy, enhanced data adaptability, interconnectivity, and integrity of data when sharing and obtaining health records between partners throughout the health-chain system—the design stores just the encoded checksum of the files.
Conclusion
Providers will be able to make sound judgments and deliver better care thanks to the data and the timeliness and accessibility of the electronic health records. The EHR can enhance patient care by improving the precision and transparency of medical records to decrease the likelihood of medical errors and keeping medical information available, cutting down on redundant testing, and speeding up treatment, also empowering patients to make better decisions and minimizing clinical errors by making health records more precise and clear.
