MR and MOI?

Published

I'm heading into my final semester in August (hooray!) and am doing a summer preceptorship in the ED. My little notebook is filled with notes of meds I've given, procedures I've seen/helped with, things to remember, diagnoses, etc etc. I have a couple of abbreviations written down and I'm not sure what they mean:

MOI -- is this mechanism of injury?

MR -- my notes say "MRs, traumas, STEMIs"...but I can't recall what MR stands for!

Thank you!

Never heard mr used like that. Bad local abbreviation. Whoever said it should've gone with "rosc" - return of spontaneous circulation.

Thanks for letting us know.

It's an accepted acronym in my ED used by everyone: doctors, RNs, and medics. We're a level 1 trauma hospital -- maybe it's a regional thing?
