Meaningful use is often times been meaningless. Worst of all it is always been backwards. Imagine if drivers were rewarded or penalized for features and safety issues and automobiles. For instance, you had to have side airbags installed in your 1959 Corvette. Not the best example, but maybe you get my drift.
Since the manufacturers or vendors of EHRs acted as if all of the meaningful use money was theirs by charging large sums of money to purchase or upgrade a system (present vendor excluded ), I believe the requirements should've been directly dropped upon the vendors. Yes they had to get certified, but look at how well interoperability works at present.
I have a tiny, tiny, Hope that the regulators will force vendors to provide truly interoperable systems. And provide the infrastructure (HIEs similar to the Fed regulating airports for instance). Oops, forgetting about TSA, ok bad example. Anyway one can hope for something meaningful.
