On general rehab, we had about 30 beds, 2 residents, 2-3 D/C's and 2-3 admits each per day on average, but that was back in the stone ages (90's...). On SCI we had around 15 beds, 1 resident, probably same averages.
At the VA, life was even cushier.
One thing that comes to mind for me - we considered SCI our hardest rotation - the most responsibility, the most time-intensive. We occasionally had a urology resident on SCI for a month - they considered it a vacation.
No one in PM&R can really complain about the schedule and admits. I did more as an inpt attending my first job out of residency than I ever did as a resident.
