Abstract

Blockchain technology is a decentralized system of recording data and performing transactions which is increasingly being used across many industries, including healthcare. It has several unique features like the validation of transaction processes, prevention of systems failure from any single point of transaction, and approval of data sharing with optimal security, to name a few. At the hospital level, blockchain technologies are used in electronic medical records systems, insurance claims systems, billing management processes, and so on. Moreover, this technology is helpful to manage logistic and human resources to achieve the quality of care in learning health systems. In many countries, blockchain is being used to promote patient-centered care by sharing patient data for remote monitoring and management. Furthermore, blockchain technology has the potential to strengthen disease surveillance systems in cases of disease outbreaks resulting in local and global health emergencies. In such conditions, blockchain can be used to identify health security concerns, analyze preventive measures, and facilitate decision-making processes to act rapidly and effectively. Despite its limitations, research, and practice based on blockchain technology have shown promises to strengthen health systems around the world, with a potential to reduce the global burden of diseases, mortality, morbidity, and economic costs.

Introduction

In the twenty-first century, many scientific innovations have changed the means of day-to-day communication, transactions, and decision-making. Blockchain is such a technology, which is being considered as one of the most significant inventions since the development of the internet.[1] It is also popularly termed as the next generation of “internet of things.”[2] The rise of Bitcoin and other cryptocurrencies have certainly helped blockchain to gain the spotlight across the globe. However, experts believe that blockchain is more than cryptocurrencies and that it may offer greater benefits to the users of complex systems.[1][3] Blockchain technology is commonly used for online money transfers and bank payments. It is also used in automobile manufacturing, cybersecurity, exit poll development, educational endevors, insurance systems, and time trend forecasting.[4] Recently, blockchain technology has gained popularity several other domains, including health systems. This is because it offers a safer and decentralized database that can operate independently from a centralized administrator.[3] According to Angraal et al., a unique selling point of the blockchain system is that once digital validation takes place, the network itself streamlines and validates the subsequent process of transaction. It safeguards the transaction history and allows data to be transferred directly between third parties.[5]

In this article, we discuss how blockchain technology works and how it can be used in complex situations like strengthening public health surveillance.

Blockchain and its applications

A blockchain is defined as “a distributed system (decentralized) which performs the dual function of recording and storing the records of the transaction. In this blockchain, the data is located in a network of personal computers called ‘nodes’ without any central control.” (Figure 1). The main advantage of this decentralized technology is that all the dealings or variations in the data are captured with real-time updates across the network.[6] The information that gets stored in each node is similar and permanent. It can't be distorted. Hence, this technology is transparent and autonomous, and as such it improves the quality of shared data between different stakeholders.[7] In this system, to validate the transaction, cryptographic algorithms are used.[8] This is different from a “trust-in-the-third-party” mechanism, where an online transaction takes place when two willing parties approve the transaction by use of a digital signature.[2] Moreover, blockchain overcomes the challenge of “single point failure,” which is common in centralized information management systems.[9] Currently, however, the average centralized healthcare system lacks the advantages offered by blockchain, including transparency and trust, data security and privacy, cost-effectiveness, and verifiability of data, as well as fast and real-time data transfer to all trusted parties.[10]
