8. ICU and ED night premium — often $2-4 above standard differential
Critical care units frequently stack an additional premium on top of the base night differential. ICU, CVICU, and ED nurses on nights commonly earn an extra $2 to $4 per hour beyond the general medical-surgical night differential at the same facility, reflecting both scarcity and acuity.
The rationale is straightforward. Night-shift ICUs run with tighter staffing, fewer support services, and higher decision latitude for the bedside nurse. Hospitals pay premiums to retain experienced critical-care staff on off-hours, especially in trauma centers and academic medical centers where night acuity can match or exceed day-shift levels.
For nurses with CCRN, CEN, or TCRN certifications, the combination of base RN wage, critical-care premium, night differential, and certification bonus can push effective hourly earnings 25 to 40 percent above a standard med-surg day-shift RN at the same hospital. Multiple hospital compensation surveys confirm this stacking pattern.
