I was a unit secretary, but I would be in the rooms with patients quite a bit, bringing them water or an extra blanket, stocking the med drawer with more supplies, etc. I also got to be a fly on the wall quite a few times as doctors spoke to patients and family.
I haven't officially shadowed any doctors. Like I said, I've been around them plenty as they interact with patients and their relatives, and I've been in the room for a handful of thoracenteses and chest tubes (moreso than anything else, as the floor where I worked got a lot of respiratory patients). I shadowed a nurse-midwife for a day, but not any doctors. I actually spoke to a cardiologist at the hospital yesterday about shadowing someone in his group (I know them from when I worked on the nursing unit) and he said sure and to call his office. I also want to shadow at least one other doctor as well, though I'm not sure who yet (I have some ideas, though).
My first choice is Jefferson, which has less of a focus on research and more on training great clinicians. I know that having more community service will strengthen my app for them more than anything else (my GPA is around their average and I'm hopeful for a score above their median MCAT).
