This comprehensive review brings together insights from four research studies that together highlight the potential of blockchain technology to be brought into healthcare systems. The first paper addresses the challenges of electronic medical records and proposes a secure storage solution based on encryption based on an attribute of a cryptographic policy, InterPlanetary File System (IPFS) storage and blockchain, which provides anti-counterfeit traceability and optional protection against keyword attacks [1]. Another paper advocates patient-based electronic health record (EHR) sharing using cloud computing and blockchain, focusing on precise access control through attribute-based and multi-keyword encryption systems. A practical Byzantine fault-tolerant consensus algorithm controlled by node state is also presented to improve the resilience of the consortium blockchain network [2]. The third paper presents insights from a systematic literature review, classifies the benefits and challenges of blockchain in data-intensive healthcare, and proposes a framework for future research [3]. Finally, the fourth article discusses blockchain and its increasing visibility in health applications, highlighting its role in changing traditional medical practices, especially in the context of the Covid-19 pandemic. The paper recommends blockchain-based tracking systems to ensure secure and accurate data sharing to meet the information security challenges of the pandemic era [4]. This synthesis provides a comprehensive understanding of blockchain and its multifaceted implications for improving safety, efficiency and patient care in healthcare systems.
