It's funny, when I did an ICU month my prelim year the EM people's signouts were the briefest, usually a few lines per patient, and they were the shortest. The longest were the med/peds people because they got into a lot of the chronic medical issues. The EM residents went into every situation where they got called to as an ABCs first and then time to think scenario while the medicine people liked to mull it over en route (assuming it wasn't something super urgent like,say, a code)
A few things to add/add to-
-you will get this the more cross cover you do but any deviations from normal night reactions should be mentioned such as
>low BP --> IV fluid --> why a patient would need less or no fluid like "patient has ESRD on dialysis"
-issues others have had overnight and how to deal with them
-things that keep coming up and have a consistent remedy like "patient has TBI and is nonverbal so will have abnormal vitals like hypertension and tachycardia but he just needs repositioned off his broken ribs"
-big social issues like "pt has a daughter that will try to make medical decisions for her demeted mother but she is not the POA"
-baseline neurologic status IF not normal/really old, can just do a brief cognitive and peripheral/motor like "patient is oriented to self and sometimes place, left hand dysfunction from war injury" to save on wasted CTs/stroke freakouts
Not needed in verbal changeover-
-stuff that has been written down on your changeover sheet
-instructions to do what anyone would do in a situation like "this patient is in with unstable angina so if he has sustained heavy chest pain get an EKG"
both are pet peeves of mine and some of my friends
