You made no mention of VISTA, the medical records system used by the Department of Veteran's Affairs. VISTA is an `in-house' invention of the VA, begun in the late 1970s. VISTA is now used by the entire VA for all medical purposes within the VA, and also some organizations that interact with the VA. The amazing thing about VISTA is this: VISTA is `open source', accessible to anyone. There is a book describing VISTA titled "Best Care Anywhere", by Phillip Longman, PoliPoint Books, www.p3books.com. The book tells where VISTA can be `downloaded' from a VA server. The VA also maintains a `dummy' VISTA system that interested people can try out. There is no chance a `comprehensive medical records system' needs to be designed `from the ground up' --- that has already been done. I do not suggest that VISTA, the way it is, is suitable for all needs of all people. Instead, I am certain VISTA can be enhanced, and perhaps even modified slightly to become 'all things for all people' --- literally --- at least for things medical. The great beauty of open source software, such as VISTA, is that anyone can make improvements, and the results are available to everyone. Proper software administration makes it impossible for unauthorized software to be used --- whether it is open source or otherwise.
