According to the dictionary, Interoperability is ability of a system to work with or use the part of equipment of another system.
Very simple and easy to articulate. But, it is the toughest to execute in the Healthcare space. Most organizations and Healthcare apps work in silos because no one has still figured out how each one can work with each other. So, until then, there will be silence but debates and ideas will exist.
For me, Interoperability does not necessarily mean that each organization has to work with each other and each app has to communicate with other apps freely. Interoperability is a framework and these guidelines are what we should be driving towards executing.
Interoperability is definitely very important component of the Future of Healthcare and it is going to play a pivotal role in the future.
