.5mg or 0.5mg. Where prescriptive rules count.

"Please don't sleep through this wake-up call.

ISMP Medication Safety Alert! Acute Care Edition. May 2, 2001.

This is an alert from the Institute for Safe Medication Practices informing readers of a fatal medication error that occurred because of a misinterpreted decimal point. The error involved administration of morphine to a 9-month-old infant who received 5 mg instead of 0.5 mg of the drug. The order did not include a zero before the decimal point, and the nurse filling the order overlooked the omission. The child suffered a cardiac arrest and died. The case illustrates the importance of clearly communicating information about medications."


A tragic story, but would you have written 0.5mg or just .5mg? If nonnative student asked you which was "correct" if written, what would you say?

The story amply illustrates how important such a practice seems to be. I certainly have no problem following that if I were in such a field and really had to "scribble" such important data.
It seems in math classes, I was always taught to put the 0 in front of decimals — definitely by the time I reached algebra.
