Hi all, I just began a new nursing job just short of three months ago. I recently made a med error where I pulled the med out of the Pyxis for the wrong patient. The pt's name were the same but middle initial was different. The correct med was given to the correct patient it was just pulled from Pyxis under the wrong name (duplicate pt names just different middle initial). No harm to pt, md notified and incident report filed. I was was given an escalated disciplinary action for this, since I am on probation at this new employer and that disciplinary action will follow me for 1 year giving my employer the ability to terminate my employment for any adverse action within the next year. This includes if I'm late or call out sick. I informed my director of the error immediately and mentioned how we don't have a similar name warning in the Pyxis. I have been an RN for 14 years and take responsibility for my actions, but feel this protocol is unjust. I asked to contest it with HR. I feel this policy of disciplinary action is wrong and voiced this to my director. It discourages nurses from trying to fix a flawed system and encourages non reporting of errors. Any advise on how to handle this with HR? Any feed back is welcome!
