No! Fail, fail, fail, fail, FAIL.
We tried to implement digi-pens at one of our hospitals (private). At great expense we got all the stationery produced, bought all the pens, did X, Y and Z to get it in.
Once it was in, what happened? Nurses misplaced the pens and started picking up biros to fill out the forms - as one put it "I don't care how it gets onto the computer, I've filled the form out". (this bit scared me as the paperwork would get filed assuming it'd be on the system)
When the nurses HAD the pens, there were issues getting them to synchronise with the database, though this was mainly because the nurses kept continually forgetting all the training they had been given in getting the information downloaded. This put massive pressure on our helpdesk with shouting nurses demanding that we do it for them (and then time spent telling them how).
The pens would BREAK. We found them to be no more or less durable than a normal biro. But once it broke, you had to order replacements (or locate spares), the person filling out a form would have to shred it and start again, etc.
Now, whilst I'm not a fan of the way things are done at the minute, we at least make sure transcription is done by non-medical (usually admin) staff. We try not to waste nurses' time with anything unnecessary like that, just as long as the information is filled out.
Plus, it didn't save massive amounts of time for our admin staff anyway - we found the handwriting recognition failed more often than it succeeded, so some poor bugger would still have to type up from a digital copy (and they didn't much like the alt-tabbing involved!)
In all, a very, very expensive waste of time. This will not help the NHS.
