The problem is when the jury your standing in front of is trying to get an explanation of what AAA is and their first thought is a roadside assistance company. The opposing lawyer will absolutely tear you apart on "what ifs" and the like. It's a cover your butt tool. The more complete you are (and this includes not using abbreviations) the less likely you will be found liable of something in a court of law.
please cite one case where that actually happened. Bet you won't find one. It's fear mongering, the attorney will tear you to shreds, blah blah blah.
How about this: I get on the stand and said pt didn't have AAA, and let the attorney ask me what it means. Abdominal Aortic Aneurysm. Attorney: Are you sure you don't mean roadside assistance? DrP: pretty sure, because it was noted when I examined his abdomen. If my documentation gets called into question, it falls upon me to explain it; not my coworker, not my supervisor, not the receiving hospital, not the garbage man, not the guy who cleans the floors, it falls on the author of the document. If you don't know, than you should ask.
Now in the hospital (as an ER tech) I use abbreviations all the time because nothing I write and hand to people gets placed in a patients chart. If I hand the nurse or doc a piece of paper that says HR, BP, and RR, with other vitals on it they know what that is...that paper does not get scanned into a patients chart or anything, it is for nursing reference.
Which is an even bigger potential for liability, because 1) they don't know if you were right or not 2) they are treating based on those vitals 3) if they are wrong, there is no proof anywhere of what you told the nurse was, when compared to what's in the chart, and if you have a "senior moment" and misread a BP of 180/60 when it's actually 80/60, and the patient is treated based on wrong information, than it falls on the nurse who entered that information in, not the tech who scribbled it on a piece of scrap paper.
"34 YOM c/o CP w/ SOB x2 days. Pt states neg Hx or home Rx..."
I can translate that very clearly actually.....
As was mentioned before, JACHO recommends not using abbreviations, except for "approved" ones. We have a list somewhere. Like many on here, I started with abbreviations on paper charts, and since we went electronic, they carried over. I know many places are trying to get away from them, but I don't see it happening any time soon.
