EMR = Electronic Medical Records
When I was an intern in the ER, one day I came back from lunch and my attending gave me this really dirty look and said, "You know, you wrote to give D5 that diabetic guy with the blood sugar of 500." (i.e. I wrote to give sugar water to a diabetic with really high blood sugar)
He shook his head at me, clearly baffled by my stupidity. "I guess you didn't do it on purpose, but I just wanted to let you know you made that mistake."
I couldn't imagine why I would have written to give him D5, even by mistake. I hadn't ordered that all year. The only thing I could think of was that maybe I had meant to order something else and I checked the wrong box, but I knew I couldn't have actually WRITTEN it.
Finally, I got the order sheet to look at what I wrote. Under NS, I had written 0.5L and they had mistaken my 0.5 to say D5. OK, I guess that's not ridiculous, but why would I have written D5L? What does that even mean???
Regardless, the patient almost got sugar water pumped into his veins.
