A Survey on Applications of Distributed Ledger Technology in Healthcare

Abstract

Blockchain technology is a distributed, accessible, open, and decentralized digital ledger used in healthcare to record transactions between devices. It addresses issues like data integrity, privacy, and confidentiality. The COVID-19 pandemic has accelerated the deployment of digital technologies, such as Distributed Ledger Technology, which enables a decentralized consensus between operational data states. This technology can enhance data access, integrity, and patients’ control over their credentials. A survey was conducted with the help of the World Health Organization, Kaggle, and the Ministry of Health Government of India and Kerala with the aim to identify potential uses for blockchain technology in immunization and the collection of patient data.
