what system are you using? We use the ESI level 5 system, there is a whole training book and video to go with it. Standardizes care and needs. Check it out! I teach the course to our new staff, and I believe there is an online course that nurses can take as well.
No new grads, no new to ER nurses; best to have at least a year's experience out there.
Level 1: death immenent, coding, MD to bedside immediately
Level 2: shouldn't wait, gets the last bed available, can wait about 10 mins for a doc, while the nurses are getting stuff done
Level 3: 2 or more resources, IV meds, labs, radiology, etc. (there are a lot of things not considered resources even though time consuming, as they are part of the regular exam such as pelvic exams)
Level 4: 1 resource ( xray, splint and sling)
Level 5: med refill (why are you even here??)
