There is certainly a feeling in the air that each place of care can't remain a "care island" in the ocean. We probably can talk a very long time about models, architectures, standards... in order to allow various form of communication. As someone that as been working on very practical solutions in that field for some years, I can introduce (very) shortly two major concepts : - Be usefull It certainly seems to be a dumb advice ; of course no one will ever build a useless system ;o) However, since we are talking about communication, the system must be usefull for each and every party. So, if you want to adress the continuity of care issue, the system must be usefull for the patient, the GP, the hospital practitionner and so on. I mean they must use it, and not only benefit from it ; so I mean the patient must use it and not only be the "center of it". - Subsidiarity It is a complex word, but the meaning is simple : let the wider system concentrate ONLY on functions that narrower systems can't offer. For us it means two orthogonal considerations : a genuine "functionnal axis" (put the proper functionnalities on the proper system), and a "data storage axis" (store the proper data on the proper systems).
