In my opinion, the definition of eHealth should refer to the use of technology to implement, facilitate, develop, and even improve all health service steps. The three domains should be considered because good data should come from a good system, so if the technology is applied in the correct way, it will help to monitor and manage any conditions (health in our hands). Then cooperation between healthcare for sharing, communicating and using patient information will be easy and manageable if technology implementation is systematically utilized (interacting for health). Moreover, the system for managing, storing, and analyzing the gathered data is also required (data enabling health).
As a consequence of this, a good healthcare system e.g. user-friendly system may induce good users and หatisfactory results.
