Evaluation of Electronics Health Record Systems Architectures

Abstract

An Electronic health record or an EHR is a patient’s digital version of their health data which is composed of observations, reports, diagnoses, remedies, and proposed treatments. These records are used to maintain any information digitally so that they can be used by health care providers to provide people with treatment and have their records stored digitally on a system. A cloud-based system is a distributed network of systems that hosts data online and it minimizes the cost of infrastructure and upkeep of such infrastructure drastically. This is ideal for developing countries that cannot spare their economic reserves for implementing such a system. A gap was identified which would allow the availability of resources for easy implementation of such a system. Our aim with this thesis is to perform a Systematic literature review that will consolidate such resources so that implementation of systems like this can be easily found. More than 80 papers were identified to discuss the appropriate system architectures and discussions from these papers are listed for the readers to aid in their implementation.
