My class was the first to have a program where we were assigned to various offices during the first two years. The idea was that, after each exam block, we would learn the physcial exam skills for a particular system, then go practice it with our preceptor for the week. It turned out to be a huge joke. About 60% of the class was only allowed to shadow the physician. We were supposed to be with primary care dos, but there werent enough to take all of us, so some were with allergists, oncologists, cardiologist, etc. These docs have estabilshed pts that they know well, and aren't about to let some medical student practice, say the neruo exam on a allergy patient! Some students in those situations were allowed to do some things (maybe listen to murmurs for example).
Bottom line... that was a waste of time. We learned the physical exam skills on each other instead and passed the physical exam test (so the faculty thinks the program was a smashing success).
