Mary Jane Samonte · 2023
Blockchain technology had developed to a level where it could serve the purposes of the healthcare sector.With EHR as one of the deliverables of E-Health, blockchain could be utilized to address issues regarding security, privacy, and interoperability.This warrants the need of a proposed system to serve as a basis to future implementations.This paper aims to rationalize the application of blockchain to the healthcare sector and deliver a proposed system for developing a blockchain-based EHR system with an integrated browser-based web application that effectively facilitates the transmission of electronic health records between authorized healthcare organizations and manages the viewership of anonymized patient data.By reviewing multiple literatures which are 35 in number, with the earliest publication on the year 2017, this study discusses the technological evolution of healthcare, the growing distrust on electronic health records, the components of blockchain, and considerations on the application of multiple blockchain model types to the healthcare sector, to rationalize the use of blockchain to the healthcare sector.Furthermore, based on findings of this study, a proposed system for developing a blockchain-based EHR system with an integrated browser-based web application that effectively facilitates the transmission of electronic health records between authorized healthcare organizations and manages the viewership of anonymized patient data is proposed.
