you know, I've heard that urban legend... that if I used an "unapproved" urban legend it would look horrible in court...
no one has been able to provide me with a single documented case of an unapproved abbreviation resulting in a court decision going against a provider.
I've never used -HAM, nor do I know what it means, but it's very likely that if you put the EMT who wrote that on a witness stand, they would know what that means.
I have been writing charts for the better part of 20 years, and not all of my abbreviations were on the "approved list." And while it might cause my QA person a little heartburn and headache, if you asked me what it means, I would be able to expand on it. and if you put me in court, I would defend the factual accounting of my narrative, coupled with the rest of the information on the PCR. You can try to get me to change it (and many have tried), but 20 years later, I want my charting to be consistent, so if I'm pulled into court, I can say, with 100% certainty what I meant, and my entire documenting history reflects my use of that particular abbreviation.
No, it doesn't, and you know that as well as I do. it stands for within normal limits, which likely would correlate to the numerical values for each vital sign that is noted elsewhere on the PCR. As long as it's documented somewhere, there is no need to duplicate information, since duplicating information increases the chances of conflicting information on a PCR, which even a poor lawyer would pick up on in court, and destroy the provider's credibility on a witness stand.
We really need to stop spreading these unfounded EMS urban legends when it comes to documentation.
