Towards interoperable e-Health system in Tanzania: analysis and evaluation of the current security trends and big data sharing dynamics

Abstract

In this paper an insight on various e-health interoperable systems was reviewed to discover strengths and challenges faced during sustainable implementation. It covered local, national and regional coverage of integrated systems towards implementation of a single unified e-health system. Peer reviewed and grey literatures were consulted to discover global and local trend and efforts towards implementations of e-health interoperable systems. The available systems and frameworks from the European Union, Asia, America, Oceania and Africa were analyzed for their strengths and challenges. Various policies, guides as well as free and proprietary standards associated with e-health interoperability was reviewed to understand the common standards adopted by the majority of existing systems. The findings of the analysis are useful for policy makers on the best ways to implement interoperable systems in developing countries by focusing on the existing infrastructures and the environment. Similarly, the strengths and challenges encountered by interoperable systems were also examined to provide recommendations for future studies.
