I don’t have the source on hand, but during my clinical informatics rotation it was mentioned that many early EMR implementations actually increased drug errors
Seeing my clinician fight the EMR to figure out what the stupid drug was called certainly didn’t help my impression of EMR systems anyway.
I wonder if that was a true rate change or a change in detection.
It was an increased rate of adverse effects due to drug mistakes, which is monitored and easily detected so unlikely due to just an increase in detection
