As of 2004, JCAHO came out with a Do Not Use list of abbreviations.


In the world of electronic charting, many of you have never written a paper prescription, but there are many opportunities even on the computer to type out your own instructions and even some of these abbreviations may find their way into the chart.  In addition, there are many hospitals that are still paper based.
