SDN Members don't see this ad. (About Ads) If I want to do an IM residency and then subspecialize, what would be the consequence of doing a Primary Care IM residency as opposed to a Categorical residency. What are the major differences between the 2? Would I be a less appealing/qualified applicant? For instance, I'd like to do an elective at Maimonides Med Ctr in NYC, but they only have a Primary Care IM program. They say these residents will have advantage over others in their fellowships. This brings me to another question...they don't have the fellowship I want. Another question...they say that the residents do 4 months of inpatient each year and they don't specifically say that residents can do electives, although they list a least 1 mo. in most of the subspecialties. Is it possible that some of those "inpatient" months are electives?
