Nowadays, a huge amount of patient records are being maintained, including medications, tests, treatments, immunisations and doctor details. However, having some of these records in papers is only possible. So, there is a growing interest towards digitalising healthcare records and maintaining healthcare data electronically. Healthcare data maintenance is essential to create a comprehensive view of patients and thereby improve patient engagement and health outcomes and suggests proactive measures to counter the rising health issues. The blockchain concept is implemented for this purpose, using which the authenticity is verified. It is done with the help of a high-level object-oriented programming language known as solidity. Furthermore, this process creates a smart contract for healthcare data. Thus, it provides a structure of data with inherent security qualities. In addition to the Blockchain, health records can be visualised in a graph known as a Knowledge Graph. Knowledge Graph is written in Neo4j browser using graph query language Cypher. This graph connects distinct quantities to represent corresponding data in a network.
