Academic hospital: NF system. 12 hour night shift. 1 resident, half an intern (they have other responsibilities), in house fellow. Cross cover 14-30+ patients, admit anywhere from none to the worst I've heard is 16. Average is 8 consistently. Attending is at home. When it's overwhelming, which for me is 5 in a couple of hours or 12+ total for the night, the fellow helps with notes and orders on some. Other people have different thresholds and ask for help earlier. Most of the time it's the resident doing the orders/notes on all the patients with supervision for procedures if needed, and we check out the plans on most patients. If stuff starts to melt down, the attending will come but that is only a once every couple of weeks type of thing. It is busy, but I feel less stress because I know I have backup.
We of course cover all blues for an enormous hospital as well.
Our VA: Home call fellow. 1 resident for ICU who also supervises all floor admissions by an intern who also cross-covers floor. Relatively few admissions. Icu tends to have 1-14 patients, luck of the draw whether your whole week is covering 3 patients and admitting none or covering 10-14 and admitting 2-3 each night. On average I'd say 5-6 patients and 2-3 admissions in a whole week. The VA is not an enjoyable place to work. You have to babysit everyone or they won't do their jobs (properly or otherwise).
