I'm not a reactionary but after having spent a few hours in the waiting area of a day surgery unit last week (where patients did have a wrist band with a QR style code) and watching the activity I wonder if the managers have any idea about the non-obvious uses of paper files?
* Attaching a patient's locker key to her file to keep it safe during the op.
* Provision of files to different theatre teams based on where they were on the central circular desk.
* At a glance checking of a patients position in the queue by where there file was in the array.
* Ad-hoc note scribbling (and diagram drawing) in the files.
* The good old fashioned thumb flicking browsing of old notes in a very thick file by an anaesthetist (presumably visually scanning for related info rather than doing a keyword search)
* Detaching forms/pieces of paper to take away to another location (colour coded forms by what I observed)
And then there's the signing of patient consent forms; and the showing them to the patient in theatre and asking "is this your signature". They'll need something better than the things I sign for parcel delivery!
All these things *can* be supported with technology but I suspect it's not as simple as people think.
