Blockchain in Critical Care

Abstract

Background and aims: Intensive care units (ICUs) face growing challenges with cybersecurity, data interoperability, medication safety, and resource management in an increasingly digital healthcare environment. This review explores how blockchain technology can address these issues and improve critical care delivery. Data sources: Relevant literature was sourced from peer-reviewed journals, healthcare cybersecurity reports, and studies on blockchain applications in medical settings. Study selection: Included works focused on blockchain's role in enhancing data security, drug traceability, consent management, and integration with AI tools in ICU contexts. Data synthesis: Blockchain offers tamper-proof health records, decentralized data sharing, and automated smart contracts, potentially transforming ICU operations. Benefits include improved patient safety, resource efficiency, and decision support. However, challenges such as scalability, regulatory concerns, and implementation costs remain. Conclusion: Blockchain holds strong potential to enhance ICU workflows and patient outcomes. Realizing its impact will require collaborative efforts and further research to overcome current limitations. How to cite this article: Gondode P, Dass C, Kumar S, Malviya A, Ashwin M, Khanna P.
