“Interoperability is one of those benefits that we won’t see right away. In fact, we’ll see little benefit from them until we hit a critical mass of EMR implementations that it’s almost futile to share information between EMR software. Kaiser and the VA are always held up as examples of successful EMR implementations and one of the main reasons for that is that they have such broad EMR adoption that they can share the clinical information across all of their clinics.”
