I've worked in Med/Surg before, and I'm currently in ER with occasional coverage of our urgent care area. It is definitely faster in pace and if you're really good and you've got good docs, you can turn patients through those rooms at a staggering pace. You have to swallow your tongue sometimes when people come in for primary care for things that really have no business there. Keep in mind that you'll need to utilize all your assessment skills though, and never run someone though because they're "just urgent care." I remember one patient who came in with a c/c of toothache that started a couple hours before. No sign of abcess or inflammation. We could have given her an Rx for a couple days of pain pills and sent her to a dentist, but something didn't seem right. Her color was slightly off and her pulse was kinda high. Turns out her tooth pain was more jaw pain, and yeah, now that we mentioned it, she did seem a little SOA today. She was actually infarcting and we got her into an ER bed and got her treated.
Lots of MRSA abcesses - too many lately that are hurtling toward necrotizing fasciitis, and what is it with people slicing those things open with dirty razors for a few days before coming in, anyhow?
Personally, I love the lacerations. Had a guy cutting wood with an axe and nearly took his thumb off. Last week it was a guy arguing with his brother and he took it out on a plate glass window (we had a discussion about finding better outlets for his anger.)
Most certainly less paperwork than med surg. Emergency care in general is less paperwork, but it's always growing, thanks to JHACO. I moved to ER because I got tired of spending the vast majority of my day charting. (And I'm not bashing Med/Surg here...It's definitely it's own specialty, and charting is my biggest weakness.) You can't let your paperwork slack though. Eventually, you'll have a patient try to claim something, or there will be an adverse outcome, and you still need your documentation to speak for itself.
So, it can be very rewarding, and you can brush off your psych skills and do some little social interventions in the ten minutes you spend with a patient. Hope you enjoy.
