3.4 Themes that develop quickly and need to be focused

Combined with literature review, among the research frontiers, E-health business is the core which is based on other articles concerned on commercialization of E-health which is experiencing explosive growth. As it goes, scholars proposed a lot of interesting and innovative project, attracting attention from the government and some companies. It seems that E-health is more cost-effective, efficient, and more convenient, which will substitute the face-to-face treatment in the future. However, Detection and Characterization of E-Health Research: A Bibliometrics (2001–2016) DOI: http://dx.doi.org/10.5772/intechopen.88610

although many of us think E-health is better than traditional treatment methods, governments operating E-health system decreased in number [75]. In view of that, we seek evidence that could help us find the reason. Since research about E-health has come into a new stage, technologies have already reached the demand, and governments are also positive that designing a complete E-health system is a top priority. Unfortunately, no one has satisfied the requirement [76]. A sustainable system need to be operated for a long time, so we need to take cost and profit into consideration. But we found that most of the research or surveys neglected these and they just concentrated on realizing E-health system [77–79]. On this occasion, how to reduce cost and profit will be the center of most scholars'study.
