It could be different where you work, but where I work we just call all occurence reports "write ups" (i.e. falls, med errors, etc). Anyway, where I work these occurence reports are used specifically for system errors and trying to find how the error could have been avoided. We are not spoken to individually (for example, if I give the wrong med to a patient, I won't be told I did it....it will come up at the next staff meeting with no names used and we try to hash out how the error could have been avoided). I don't know what happens if there's a sentinel event, though. I'm sure I'd hear about that! But, if they wrote up the med error and it's to be used to find how the error could have been avoided...let it go. The above poster is correct, I'm not sure how you can prove you put it on the correct foot. I supposed anything could have happned, it could have fallen off and maybe another staff member replaced it, a family member, the patient, etc. There are too many variables. If you are being formerly written up, I think I'd try to argue my side, though. Good luck!
