None of my doctors used bound sets, all have converted all of their records to computer files. But every year I have to fill out the same paper forms and a clerk transcribes the data into their computer.
You'd think that the update procedure would be computerized by now.
The only doctor I see regularly, i.e. annually, is my ophthalmologist, and he's never even asked me to update, let alone redo my paperwork.
I dunno... Degree of paranoia, i.e. fear of lawsuits, or (foolish?) lack thereof?
