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.
