hospital IT systems are big , complex , require training, have bugs , generate changes , etc etc... that's basiclly the essence of your rant. probably like any computer system in any complex organization.

But

they have huge potential(in the long term) , when done properly to transform medicine , reduce costs , prevent errors , give better treatments, enable better research , etc, etc.

In essence , medical IT systems are a huge problem , with a huge payoff. should'nt we tackle the problem because it's huge ?
