e-Health application, implementation and challenges: A literature review

Background: World Health Organization, through a partnership with European Union, encourages the implementation e-health systems. E-health is a relatively old concept that is upgraded with new technologies and is directed toward monitoring different health conditions with the help of technology. Objectives: This paper's main objective is to demonstrate e-health application possibilities in today's healthcare organisations and its impact on the quality of provided health care services using ISO/TR 14639 Health informatics Capacity-based eHealth architecture roadmap. Methods/Approach: In this paper, we used the e-health architecture model for literature review based on individual areas of the model - ICT infrastructure, e-health infastructure, health process domain components, governance and national ownership. Results: Research confirms that new technologies have a favourable and significant impact on population health; however, more developed countries show a better understanding of the concept and are moving towards implementing laws and regulations for e-health practices. Conclusions: Through this research, we concluded that new technology significantly impacts health, but this impact is limited due to different development of countries. That is why it is very important to develop health literacy, which is the ability to comprehend, access, retrieve, and use health information or health services.
