We do need to make things more efficient. But it's lazy of us tech types to fall for centralisation in its most naive form — centralisation of personal data storage always comes with huge risks. We overstate the benefits, and we're not around to pay the price when the benefits fail to pass and the hidden costs creep out.
Instead, we should be pushing the health record out to individuals, and away from the centre. We should own our own data — perhaps it should even reside on our own device. Our governments should be pushing to store less data, not more.
