I matched into a very busy IM residency. I did a sub-i at another similarly busy IM residency but I wasn't exactly treated as an intern, more like a 3rd year med student with minimal responsibility of covering 2 or 3 patients. Except for a few days when a couple of the interns were out and they did treat me like an intern out of necessity. Those days where I was the intern I was lost. The patient list was anywhere from 20-30 patients and I was supposed to know everything about them even if they weren't the patients I was specifically covering. Attendings or other residents would page me and ask me questions about any of the patients and I would be fumbling when they expected me to know the answers cold. The questions weren't necessarily medical questions, more like clerical questions (Did this patient get this med today? What did the consult say about that patient? Has this patient gone down for this procedure? Has PT seen that patient today? etc). In a few short months I will be an intern and the residency I'm going to is as busy. The interns where I did my sub-i were on top of it. They knew EVERYTHING about EVERY patient on the census. How do you guys remember and keep track of everything about every patient when you're covering 20-30 of them?
