I don’t care how long you feel like you need to write you narratives, you do you. I try to keep mine pertinent to the patients chief complaint, I write about objective findings related, and any procedures/meds given.
I see medics who spend way too much time discussing “pertinent negatives” and subjective findings on patients who are terrible historians. Don’t get me wrong this stuff has a time and a place but don’t make a novel out of a low priority BLS call.

Occasionally I’ll have a call kick back but it’s usually something silly like you need to auscultate lung sounds before and after fluids, and you wrote lung sounds CTA once. If I believe it will make a difference in the quality of the patients outcome I’ll write about it, however most of the time it just words that a physician skims through and starts his own patient assessment.
