  eHealth (Health Informatics/Medical Informatics) field is growing worldwide
due to acknowledge of reputable Organizations such as World Health
Organization, Institute of Medicine in USA and several others. This field is
facing number of challenges and there is need to classify these challenges
mentioned by different researchers of this area. The purpose of this study is
to classify different eHealth challenges in broader categories. We also
analyzed recent eHealth Applications to identify current trends of such
applications. In this paper, we identify stakeholders who are responsible to
contribute in a particular eHealth challenge. Through eHealth application
analysis, we categories these applications based on different factors. We
identify different socio-economic benefits, which these applications can
provide. We also present ecosystem of an eHealth application. We gave
recommendations for eHealth challenges relevant to Information Technology
domain. We conclude our discussion by specifying areas for future research and
recommending researchers to work on identify which type of disease can control
and manage by different eHealth applications.
