Application of Blockchain Technology in Hospital Information System

lockchain is a distributed database of cryptographically chained blocks that aggregates value exchange transactions in a chronological order. Each block in the blockchain is immutably recorded across a peer-to-peer (P2P) network, and each one is cryptographically linked to the previous block. Meanwhile, the hospital information system (HIS) is a comprehensive, standardised information system designed to organise the hospital's financial, administrative, and clinical functions. The goal of launching HIS was to increase the quality of public healthcare services, notably in terms of patient satisfaction and record management. HIS
Blockchain technology was found to be useful in the real healthcare environment, mainly on the management of electronic medical records, biomedical research and education, remote patient monitoring, pharmaceutical supply chain, health insurance claims, health data analytics, and some other potential areas. The main reasons for the implementation of blockchain technology in the healthcare sector are data integrity, access control, data logging, data versioning, and non-repudiation.

The current HIS, which is mainly cloudbased, has several issues that influence its efficiency and effectiveness. HIS incorporates the system of computer and improves the service efficiency, which concentrates on patient, ancillary, admission, financial, and clinical applications. HIS consists of at least two of the following components: 1. Clinical Information System (CIS), 2. Financial Information System (FIS), 3. Laboratory Information System (LIS), 4. Nursing Information System (NIS), 5. Pharmacy Information System (PIS), 6. Picture Archiving Communication System (PACS), 7. Radiology Information System (RIS).
