Last year I got certified as an EMT. As part of the training I shadowed an ambulance for a day and assisted with each run. For each patient we treated, we had to fill out a patient care report.

The ambulance I shadowed had an ePCR. Nobody used it. I talked to the EMTs about this, and they said nobody they knew used it either. Lack of training? «No, we all got trained.» Crippling bugs? No, it worked fine. Paper was good enough? No, the ePCR was much better than paper PCRs in almost every way. It just had one problem: it was too slow.

It wasn’t even that slow. Something like a quarter-second lag when you opened a dropdown or clicked a button. But it made things so unpleasant that nobody wanted to touch it. Paper was slow and annoying and easy to screw up, but at least it wasn’t that.

I think about that a lot.
