niryaam,
You are not confused..
I understand your question. It is one I too am dealing with. Primary Care IM programs usually train their docs toward a primary care career by making a good percentage of their training in the ambulatory realm. The Categorical program or "Traditional" training simply has more inpatient exposure.
What I was told is that primary care programs have less inpatient months and you are at a disadvantage to making the contacts that are important in getting a fellowship position (like it or not ...alot of getting a fellowship is "good ole boy or girl" network). Where the categorical resident is doing several cardiology, GI, and Hem/onc rotations and showing his/her stuff; the primary care resident is sacrificing some of those experiences for the benefit of more ambulatory months in their programs.
But even with that being said, I know several people from primary care IM programs doing fellowships. I plan to persue fellowship training after residency, and I have a couple of primary care programs I am applying to at some of the stronger academic programs.
Ask what the graduating class of the primary care program is doing after this year of the programs that you are interested (I think a good number of program websites also have that info on them).
peace,
