Here's one issue I don't see discussed often here: Task switching. In Ortho, you get to do one hip arthroplasty at a time. Yeah you might have 4 of them to do in a day and maybe be you're at the hospital from 6am to 8pm, but generally you concentrate one one patient at a time. Maybe a PA or someone comes into the OR to discuss a consult with you, whatever.
In EM, you are constantly task switching. See an ankle sprain, get interrupted for an EKG, write half a note get interrupted for a zofran order, sign another EKGs, resume the note you were on, interrupted for patient that you DC already that now "has more questions", see an abdominal pain that has a billion tangents, go back to note #1, interrupted by a "stroke alert" that's really a febrile altered 90 year old, wait where was I on note #1?, sign another EKG, answer BS phone call from radiology about patient they don't want to give contrast to, sign another EKG, pulled to see dying toddler for 2 hours. Repeat repeat repeat.
Spoiler alert: no matter how good you think you are at "multi tasking", you are not good at multi tasking. We know this from science. It's been studied. Humans are not wired for this.
But guess what? You're still expected to be perfect. And be fast. And provide a good "patient experience." If you think good, fast, nice are three factors that you cannot feasibly maximize, you'd be right, because the system is designed so that you can it possibly maximize all three. You can do 2/3 at best.
Task switching makes you more agitated, at work and at home. It decreased your attention span, at work and at home. It decreases your short term memory recall, at work and at home.
If you have good nurses they can shield you from some of this, but not all. Certain geographic setups can also help, like being in an enclosed docbox, but again, not perfect.
Add to this the constant soundtrack of patients screaming, gomers letting out their animal calls, and monitors alarming to signal nothing, and it's a cacaphony of bull crap. Yet, you are tasked with picking out the 1% signal through all that noise, every time, with perfection.
