Peregrin's comments are accepted widely at MSU at the COM (osteopathic) school as well. Respect is seemingly mutual between the classes, of course there will be students on either side that do not share this opinion.
Our curriculum differs slightly in the first year and greatly in our second year at school. The third and fourth year rotations are mostly the same, except for the first sixth months.
In our first year at MSU our basic sciences are together. At COM, we have a clinical skills class our first semester, learning to use our stethoscopes, opthalmoscopes, bp cuffs, and physical exam skills. By our second semester the CHM students begin their clinical skills classes and COM has their last formal clinical skills class where, amazingly enough, we perform our first male and female genital exams. Additionally, COM students have OMM (manipulation classes) each semester at school.
This summer COM students begin their first systems course- NMS (neuromusculoskeletal). This course refreshes our memory of gross anatomy, physiology, biochemistry, neuroanatomy, and OMM by packaging information in clinical applications lectures and labs. Great class for remembering material from the first two semesters and expanding on that information.
By the second year, CHM and COM split ways, unfortunately. It would be nice to hang out with our classmates for both years for the basic science portions. CHM like peregrin said is problem based learning modules (self-study units with recitations). In COM we have systems based lectures given 4 days a week for 4+ hours a day. Half of the Fridays in each semester are spent in a preceptors office, practicing our history and physical exam skills (learning to be more independent, basically).
In our third year, at COM, we spend either the first or second six months in PCAC (primary care ambulatory clerkship). PCAC is a way to reinforce the Osteopathic commitment toward primary care medicine. Basically, a student will rotate through the primary care fields in these six months in an ambulatory setting (outside the hospital-most of the time, must be 60% of the time).
Sorry for the long-winded post. Hope this aids your understanding of the respect shared and differences in the curriculums here at MSU.
