Sure, but the "alternative" model we have just been discussing involves
direct P2P connections - no middleman, no tollbooth. That's the whole
point. The only bits of centralised infrastructure which are required
are a PKI and an associated directory service for Web services. and even
both of these can be run in a distributed or federated fashion.
Tim,
Once the NEHTA standards are ironed out and the government feels in a
mood to fund an implementation of HealthConnect, don't you fully expect
that the central repository at Medicare Australia for the summaries will
be revived?
In my interpretation of things, the government stepping back hasn't
changed this model, and, as the recent changes to the smartcard
initiative has amply demonstrated, as soon as serious money gets
approved by government the mandarins step in to insure it enhances their
empires.
Early iterations of the HealthConnect model had summary data stored at
Division level. These ideas are a distant memory, even though we've been
made dependent on a separate data-mining exercise, the feasibility and
utility of which are still to be demonstrated.
