One of the big issues in healthcare IT is and has been interoperability. Interoperability not only of systems, but of data. We've discussed eMAR, but that information is not just critical in the present environment of the patient, say a hospital or nursing home, but its important that data stay with the patient wherever they go. What happens when they check out of a facility? There needs to be a continuum of data, from the time they first were admitted in one facility to when they check into another facility. Suppose they check into a nursing home, then goto the hospital and then to an assisted living facility? What if each facility uses a different pharmacy?
