I will get slammed, and rightly so, anyone upset with me, i would have no good argument,
but,
i always kept my assignment sheets, at my home! for eons. No one knew of it, ever, and after several years, i burned them.
why did i do this?
first off, when i first began the habit, HIPAA was not much of a big deal decades ago, not like it is today.
second off, i have horrible memory, and this did help, if my boss would tell me about remarks on a patient survey, or other 'after care' discussions that came up, when i went home and looked over my notes, it all came back to me. (my memory for names is so dreadful, that i often wrote lil identifiers next to each pt's name, like "big mustache" or "loves dogs" or whatever, to help me bring that pt to mind.) Without my notes, i always felt like idiot, that i could not recall whoever it was being discussed. At the time, i saw this as secretly working around some name-recognition deficit that i have.
I wouldn't do this NOWadays, but, i used to.
anyone appalled, i pre-agree, and pre-apologize. You are right.
