The latest developments and advancements in the computer science and information technology promise a massive potential that can be harnessed for the improvement of healthcare services especially in the developing countries, this being one of the most challenging issues faced by them. With the advent of cloud computing, distributed databases, robotics, data mining and knowledge discovery mechanisms, the healthcare services can benefit in a great way. Medical or Health Informatics as a sub-domain of Computer Science has a long way to go.
In this study, latest trends in different nations, various areas of application where technology can prove helpful, the potential benefits, the techniques and the related implementation issues underlying them have been figured out. Finally, a nationalized framework from India's perspective wherein the biggest healthcare institutes of the country can be connected to the statewide leading hospitals which are further connected to those in the districts along with the primary health centers has been proposed. Such an arrangement can really help the masses that cannot possibly benefit from the best quality of health services being typically concentrated near larger cities due to financial or geographical constraints. In this way, they can get their ailments studied by specialized physicians all over the world in a more logistical manner. Moreover, a national repository of information over a network will contribute in the research for providing even better healthcare services to the citizens of the country.
