The capiTAL letters are only for part of the word e.g. FLUOxetine. Im looking into the research as mentioned by WebFerret.
There seems to be two aspects to errors.
Firstly, the simple act of not seeing what is actually in front of you. So you have a box of propranolol in your hand and see it as prednisilone. This is called 'inattentional blindness' check out this article from the Institute of Safe Medicine Practices (ISMP)
Inattentional blindness: What captures your attention?.
Secondly, the fact that you just dont know something e.g. you get a prescription for diclofenac 50mg E/C MR. I was never taught at university that such a preperation existed so I may just dispense the usual diclofenac tablets which I am familiar with, rather than the M/R preparation, without even realising its a mistake. This is called a blindspot i.e. information which other people know, but I dont know. Just like driving a car and pulling into the right hand lane, not seeing the car to your right, even though the driver in the right hand lane can see you.
I think it would be worthwhile to tackle this second aspect.
A list of drugs or situations which should cause you to automatically 'think'.
e.g. Methotrexate = Think...weekly dose
Diclofenac 50mg = Think...is it M/R or E/C or both
Peppermint oil 0.2ml = Think...is it M/R
Any thoughts?
